              [<EM>terminal-type</EM> ... ]


</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       <STRONG>infocmp</STRONG>  reports  a  human-readable  terminal  type  description from a
       compiled entry in the <EM>terminfo</EM> database  in  a  variety  of  selectable
       formats,  compares such entries to each other, and rewrites an entry to
       replace  "<STRONG>use</STRONG>"  expressions  with  the  content  of  other  entries  by
       reference.   A  <EM>terminfo</EM> <EM>entry</EM> comprises a list of one or more terminal
       type identifiers, a human-readable description of  the  terminal  type,
       and  a  list of terminal <EM>capabilities</EM> that characterize its programming
       interface.   In  all  cases,   the   program   reports   Boolean-valued
       capabilities  first,  followed  by numeric ones, and then string-valued
       capabilities.


</PRE><H3><a name="h3-Default-Options">Default Options</a></H3><PRE>
       If  no  options  are  specified  and  zero  or  one  <EM>terminal-types</EM>  is
       specified,  <STRONG>infocmp</STRONG>  assumes  the  <STRONG>-I</STRONG>  option.   If  more  than  one is
       specified, the program assumes the <STRONG>-d</STRONG> option.


</PRE><H3><a name="h3-Source-Listing-Options_I_L_C_r_">Source Listing Options [-I] [-L] [-C] [-r]</a></H3><PRE>
       The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will  produce  a  source  listing  for  each
       terminal named.

                   <STRONG>-I</STRONG>   use <EM>terminfo</EM> capability codes
                   <STRONG>-L</STRONG>   use "long" capability names
                   <STRONG>-C</STRONG>   use <EM>termcap</EM> capability codes
                   <STRONG>-r</STRONG>   with <STRONG>-C</STRONG>, include nonstandard capabilities
                   <STRONG>-K</STRONG>   with <STRONG>-C</STRONG>, improve BSD compatibility

       If  no  <EM>terminal-types</EM> are given, the environment variable <EM>TERM</EM> will be
       used for the terminal name.

       The source produced by the <STRONG>-C</STRONG> option may be used directly as a  <STRONG>termcap</STRONG>
       entry,  but not all parameterized strings can be changed to the <STRONG>termcap</STRONG>
       format.  <STRONG>infocmp</STRONG> will attempt to  convert  most  of  the  parameterized
       information,  and  anything not converted will be plainly marked in the
       output and commented out.  These should be edited by hand.

       For best results when converting to <STRONG>termcap</STRONG> format, you should use both
       <STRONG>-C</STRONG> and <STRONG>-r</STRONG>.  Normally a termcap description is limited  to  1023  bytes.
       <STRONG>infocmp</STRONG>  trims  away  less  essential parts to make it fit.  If you are
       converting to one of the (rare) termcap implementations which accept an
       unlimited size of termcap, you may want to add  the  <STRONG>-T</STRONG>  option.   More
       often  however,  you  must  help  the  termcap implementation, and trim
       excess whitespace (use the <STRONG>-0</STRONG> option for that).

       All padding information for strings  will  be  collected  together  and
       placed  at  the  beginning  of  the  string  where  <STRONG>termcap</STRONG> expects it.
       Mandatory padding (padding information with a trailing "/") will become
       optional.

       All <STRONG>termcap</STRONG> variables no longer supported by <STRONG>terminfo</STRONG>,  but  which  are
       derivable  from  other  <STRONG>terminfo</STRONG>  variables,  will  be output.  Not all
       <STRONG>terminfo</STRONG> capabilities will be translated; only  those  variables  which
       were part of <STRONG>termcap</STRONG> will normally be output.  Specifying the <STRONG>-r</STRONG> option
       will  take off this restriction, allowing all capabilities to be output
       in <EM>termcap</EM> form.  Normally you would use both the <STRONG>-C</STRONG>  and  <STRONG>-r</STRONG>  options.
       The  actual  format  used  incorporates  some  improvements for escaped
       characters  from  terminfo  format.   For  a  stricter   BSD-compatible
       translation, use the <STRONG>-K</STRONG> option rather than <STRONG>-C</STRONG>.

       Note  that  because  padding  is  collected  to  the  beginning  of the
       capability, not all capabilities are output.  Mandatory padding is  not
       supported.   Because  <STRONG>termcap</STRONG>  strings  are  not as flexible, it is not
       always possible  to  convert  a  <STRONG>terminfo</STRONG>  string  capability  into  an
       equivalent <STRONG>termcap</STRONG> format.  A subsequent conversion of the <STRONG>termcap</STRONG> file
       back  into  <STRONG>terminfo</STRONG> format will not necessarily reproduce the original
       <STRONG>terminfo</STRONG> source.

       Some common <STRONG>terminfo</STRONG> parameter sequences,  their  <STRONG>termcap</STRONG>  equivalents,
       and some terminal types which commonly have such sequences, are:

                 <STRONG><EM>terminfo</EM></STRONG>                   <STRONG><EM>termcap</EM></STRONG>   Terminal Types

</PRE><H3><a name="h3-Entry-Comparison-Options_d_c_n_">Entry Comparison Options [-d] [-c] [-n]</a></H3><PRE>
       Given  <STRONG>-c</STRONG>,  <STRONG>-d</STRONG>, or <STRONG>-n</STRONG>, <STRONG>infocmp</STRONG> compares the <EM>terminfo</EM> description of the
       first specified <EM>terminal-type</EM> with those  of  each  of  the  subsequent
       operands.  If fewer <EM>terminal-types</EM> than required are specified, <STRONG>infocmp</STRONG>
       uses the environment variable <EM>TERM</EM> in their place.

       If  a  capability  is  defined  for  only  one terminal type, the value
       reported depends on the capability's type:

       <STRONG>o</STRONG>   <STRONG>F</STRONG> for missing Boolean variables

       <STRONG>o</STRONG>   <STRONG>NULL</STRONG> for missing integer or string variables

       The <STRONG>-c</STRONG> and <STRONG>-d</STRONG> options  report  string  capability  values  between  "'"
       characters.   Use  the  <STRONG>-q</STRONG>  option  to  distinguish <EM>absent</EM> and <EM>canceled</EM>
       capabilities; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.

       The comparison option selects the form of report.

       <STRONG>-d</STRONG>   lists each capability that  <EM>differs</EM>  between  two  entries.   Each
            capability  name is followed by ":" and comma-separated capability
            values, then a period.

       <STRONG>-c</STRONG>   lists each capability that two entries have  in  <EM>common</EM>.   <STRONG>infocmp</STRONG>
            ignores  capabilities  missing from either entry.  Each capability
            name is followed by "=", a space, and the capability value, then a
            period.

            If the <STRONG>-u</STRONG>  option  is  further  specified,  <STRONG>infocmp</STRONG>  rewrites  the
            description  of  the first type employing "use=" syntax to use the
            second as a building block.

       <STRONG>-n</STRONG>   lists capabilities that are in <EM>none</EM> of the  given  entries.   Each
            capability name is preceded by "!"  and followed by a period.

            Normally  only  conventional  capabilities  are shown.  Use the <STRONG>-x</STRONG>
            option to add BSD-compatibility capabilities (names prefixed  with
            "OT").


</PRE><H3><a name="h3-Use_Option_u_">Use= Option [-u]</a></H3><PRE>
       The  <STRONG>-u</STRONG>  option  produces  a  <STRONG>terminfo</STRONG>  source description of the first
       terminal <EM>terminal-type</EM> which is relative to the sum of the descriptions
       given by the entries for the other <EM>terminal-types</EM>.   It  does  this  by
       analyzing  the  differences  between  the  first <EM>terminal-types</EM> and the
       other <EM>terminal-types</EM> and producing a description with <STRONG>use=</STRONG>  fields  for
       the  other  terminals.   In  this  manner,  it  is possible to retrofit
       generic terminfo entries into a terminal's  description.   Or,  if  two
       similar  terminals  exist,  but  were  coded  at  different times or by
       different people so that each description is a full description,  using
       <STRONG>infocmp</STRONG>  will  show  what  can  be done to change one description to be
       relative to the other.

       A capability will be printed with an at-sign (@) if it no longer exists
       in the first <EM>terminal-type</EM>, but one of the other <EM>terminal-type</EM>  entries
       contains  a  value for it.  A capability's value will be printed if the
       value in the first <EM>terminal-type</EM> is not  found  in  any  of  the  other
       <EM>terminal-type</EM>  entries,  or  if  the  first  of the other <EM>terminal-type</EM>
       entries that has this  capability  gives  a  different  value  for  the
       capability than that in the first <EM>terminal-type</EM>.

       The order of the other <EM>terminal-type</EM> entries is significant.  Since the
       terminfo  compiler  <STRONG>tic</STRONG>  does a left-to-right scan of the capabilities,
       specifying two <STRONG>use=</STRONG> entries that contain differing entries for the same
       capabilities will produce different results depending on the order that
       the entries are given in.  <STRONG>infocmp</STRONG> will flag any  such  inconsistencies
       between the other <EM>terminal-type</EM> entries as they are found.

       Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry that contains
       that  capability  will  cause  the  second specification to be ignored.
       Using <STRONG>infocmp</STRONG> to recreate a description can be a useful check  to  make
       sure  that  everything  was  specified correctly in the original source
       description.

       Another error that does not cause incorrect compiled  files,  but  will
       slow  down  the  compilation time, is specifying extra <STRONG>use=</STRONG> fields that
       are superfluous.  <STRONG>infocmp</STRONG> will flag any other <EM>terminal-type</EM> <EM>use=</EM> fields
       that were not needed.

       Like  other  <EM>ncurses</EM>  utilities,  <STRONG>infocmp</STRONG>  looks   for   the   terminal
       descriptions   in  several  places.   You  can  use  the  <EM>TERMINFO</EM>  and
       <EM>TERMINFO</EM><STRONG>_</STRONG><EM>DIRS</EM> environment variables to override the compiled-in default
       list of places to search.  See <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>,  as  well  as  the  <EM>Fetching</EM>
       <EM>Compiled</EM> <EM>Descriptions</EM> section in <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.

       You  can  also use the options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> to override the list of places
       to search when comparing terminal descriptions:

       <STRONG>o</STRONG>   The <STRONG>-A</STRONG> option sets the location for the first <EM>terminal-type</EM>

       <STRONG>o</STRONG>   The <STRONG>-B</STRONG> option sets the location for the other <EM>terminal-types</EM>.

       Using these options, it is  possible  to  compare  descriptions  for  a
       terminal  with  the  same name located in two different databases.  For
       instance, you can use this feature for comparing descriptions  for  the
       same terminal created by different people.


</PRE><H3><a name="h3-Other-Options">Other Options</a></H3><PRE>
       <STRONG>-0</STRONG>   causes the fields to be printed on one line, without wrapping.

       <STRONG>-1</STRONG>   causes the fields to be printed out one to a line.  Otherwise, the
            fields  will be printed several to a line to a maximum width of 60
            characters.

       <STRONG>-a</STRONG>   tells <STRONG>infocmp</STRONG> to retain  commented-out  capabilities  rather  than
            discarding  them.   Capabilities  are  commented by prefixing them
            with a period.

       <STRONG>-D</STRONG>   tells <STRONG>infocmp</STRONG> to print the database locations that it knows about,
            and exit.

       <STRONG>-E</STRONG>   Dump the capabilities of the given terminal as tables,  needed  in
            the   C   initializer  for  a  TERMTYPE  structure  (the  terminal
            capability structure in the <STRONG>&lt;term.h&gt;</STRONG>).  This option is useful  for
            preparing  versions  of  the  curses library hardwired for a given
            terminal type.  The tables are all declared static, and are  named
            according  to  the type and the name of the corresponding terminal
            entry.

            Before <EM>ncurses</EM> 5.0, the split between the <STRONG>-e</STRONG> and  <STRONG>-E</STRONG>  options  was
            not  needed;  but  support  for extended names required making the
            arrays  of  terminal  capabilities  separate  from  the   TERMTYPE
            structure.

       <STRONG>-e</STRONG>   Dump the capabilities of the given terminal as a C initializer for
            a  TERMTYPE  structure  (the  terminal capability structure in the
            <STRONG>&lt;term.h&gt;</STRONG>).  This option is useful for preparing  versions  of  the
            curses library hardwired for a given terminal type.

       <STRONG>-F</STRONG>   compare terminfo files.  This assumes that two following arguments
            are  filenames.   The  files  are  searched  for  pairwise matches
            between entries, with two entries considered to match  if  any  of
            their  names  do.   The  report  printed  to standard output lists
            entries with no matches in the other file, and entries  with  more
            than  one match.  For entries with exactly one match it includes a
            difference report.  Normally, to reduce the volume of the  report,
            use  references  are  not resolved before looking for differences,
            but resolution can be forced by also specifying <STRONG>-r</STRONG>.

       <STRONG>-f</STRONG>   Display complex terminfo strings which contain  if/then/else/endif
            expressions indented for readability.

       <STRONG>-G</STRONG>   Display  constant  literals  in  decimal  form  rather  than their
            character equivalents.

       <STRONG>-g</STRONG>   Display constant character literals in  quoted  form  rather  than
            their decimal equivalents.

       <STRONG>-i</STRONG>   Analyze  the  initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>,
            <STRONG>rs3</STRONG>),  strings  in  the  entry,  as  well  as   those   used   for
            starting/stopping  cursor-positioning  mode (<STRONG>smcup</STRONG>, <STRONG>rmcup</STRONG>) as well
            as starting/stopping keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).

            For each string, the code tries to  analyze  it  into  actions  in
            terms  of  the  other capabilities in the entry, certain X3.64/ISO
            6429/ECMA-48 capabilities, and certain DEC VT-series private modes
            (the set of recognized special sequences  has  been  selected  for
            completeness  over  the  existing terminfo database).  Each report
            line consists of the capability name,  followed  by  a  colon  and
            space,  followed by a printable expansion of the capability string
            with  sections  matching  recognized   actions   translated   into
            {}-bracketed descriptions.

            Here is a list of the DEC/ANSI special sequences recognized:

                      Action        Meaning
                      -----------------------------------------

                      DECSTR        soft reset (VT320)
                      S7C1T         7-bit controls (VT220)

                      -----------------------------------------
                      DECPAM        application keypad mode
                      DECPNM        normal keypad mode
                      DECANSI       enter ANSI mode
                      -----------------------------------------

                      ECMA[+-]IRM   insert replace mode
                      ECMA[+-]SRM   send receive mode
                      ECMA[+-]LNM   linefeed mode
                      -----------------------------------------
                      DEC[+-]CKM    application cursor keys
                      DEC[+-]ANM    set VT52 mode
                      DEC[+-]COLM   132-column mode
                      DEC[+-]SCLM   smooth scroll
                      DEC[+-]SCNM   reverse video mode
                      DEC[+-]OM     origin mode
                      DEC[+-]AWM    wraparound mode
                      DEC[+-]ARM    auto-repeat mode

       It also recognizes a SGR action corresponding to ANSI/ISO 6429/ECMA Set
       Graphics Rendition, with the values NORMAL, BOLD, UNDERLINE, BLINK, and
       REVERSE.  All but NORMAL may be prefixed with

              <STRONG>o</STRONG>   "+" (turn on) or

              <STRONG>o</STRONG>   "-" (turn off).

              An  SGR0  designates  an empty highlight sequence (equivalent to
              {SGR:NORMAL}).

       <STRONG>-l</STRONG>   Set output format to terminfo.

       <STRONG>-p</STRONG>   Ignore padding specifications when comparing strings.

       <STRONG>-Q</STRONG> <EM>n</EM> Rather than show source  in  terminfo  (text)  format,  print  the
            compiled  (binary) format in hexadecimal or base64 form, depending
            on the option's value:

               1  hexadecimal

               2  base64

               3  hexadecimal and base64

            For example, this prints the compiled terminfo value as  a  string
            which could be assigned to the <EM>TERMINFO</EM> environment variable:

                infocmp -0 -q -Q2

       <STRONG>-q</STRONG>   This makes the output a little shorter:

            <STRONG>o</STRONG>   Make  the  comparison listing shorter by omitting subheadings,
                and using "-" for absent capabilities, "@" for canceled rather
                than "NULL".

            <STRONG>o</STRONG>   However,  show  differences  between   absent   and   canceled
                capabilities.

            <STRONG>o</STRONG>   Omit the "Reconstructed from" comment for source listings.

       <STRONG>-R</STRONG><EM>subset</EM>
            Restrict  output  to  a given subset.  This option is for use with
            archaic versions of terminfo like those on SVr1, Ultrix, or  HP-UX
            that  do not support the full set of SVR4/XSI Curses terminfo; and
            variants such as AIX that have their own  extensions  incompatible
            with SVr4/XSI.

            <STRONG>o</STRONG>   Available  terminfo  subsets  are  "SVr1", "Ultrix", "HP", and
                "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for details.

            <STRONG>o</STRONG>   You can also  choose  the  subset  "BSD"  which  selects  only
                capabilities with termcap equivalents recognized by 4.4BSD.

            <STRONG>o</STRONG>   If  you  select  any  other value for <STRONG>-R</STRONG>, it is the same as no
                subset, i.e., all capabilities are used.

            A few options override the subset selected with <STRONG>-R</STRONG>,  if  they  are
            processed later in the command parameters:

            <STRONG>-C</STRONG>   sets the "BSD" subset as a side effect.

            <STRONG>-I</STRONG>   sets the subset to all capabilities.

            <STRONG>-r</STRONG>   sets the subset to all capabilities.

       <STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
            The  <STRONG>-s</STRONG>  option sorts the fields within each type according to the
            argument below:

            <STRONG>d</STRONG>    leave fields in  the  order  that  they  are  stored  in  the
                 <EM>terminfo</EM> database.

            <STRONG>i</STRONG>    sort by <EM>terminfo</EM> name.

            <STRONG>l</STRONG>    sort by the long C variable name.

            <STRONG>c</STRONG>    sort by the <EM>termcap</EM> name.

            If  the  <STRONG>-s</STRONG>  option  is  not given, the fields printed out will be
            sorted alphabetically by  the  <STRONG>terminfo</STRONG>  name  within  each  type,
            except  in  the  case of the <STRONG>-C</STRONG> or the <STRONG>-L</STRONG> options, which cause the
            sorting to be done by the <STRONG>termcap</STRONG> name  or  the  long  C  variable
            name, respectively.

       <STRONG>-T</STRONG>   eliminates  size-restrictions  on  the  generated  text.   This is
            mainly  useful  for  testing  and  analysis,  since  the  compiled
            descriptions  are  limited  (e.g.,  1023  for  termcap,  4096  for
            terminfo).

       <STRONG>-t</STRONG>   tells <STRONG>tic</STRONG> to discard commented-out  capabilities.   Normally  when
            translating  from terminfo to termcap, untranslatable capabilities
            are commented-out.

       <STRONG>-U</STRONG>   tells <STRONG>infocmp</STRONG> to not  post-process  the  data  after  parsing  the
            source  file.   This  feature  helps  when  comparing  the  actual
            contents of two source files, since  it  excludes  the  inferences
            that <STRONG>infocmp</STRONG> makes to fill in missing data.

       <STRONG>-V</STRONG>   reports the version of <EM>ncurses</EM> which was used in this program, and
            exits.

       <STRONG>-v</STRONG> <EM>n</EM> prints  out  tracing  information on standard error as the program
            runs.

            The optional parameter <EM>n</EM> is a number  from  1  to  10,  inclusive,
            indicating the desired level of detail of information.  If <EM>ncurses</EM>
            is  built  without  tracing  support,  the  optional  parameter is
            ignored.

       <STRONG>-W</STRONG>   By itself, the <STRONG>-w</STRONG>  option  will  not  force  long  strings  to  be
            wrapped.  Use the <STRONG>-W</STRONG> option to do this.

       <STRONG>-w</STRONG> <EM>width</EM>
            changes the output to <EM>width</EM> characters.

       <STRONG>-x</STRONG>   print information for user-defined capabilities (see <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>.
            These  are  extensions  to  the  terminfo  repertoire which can be
            loaded using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>.

       X/Open Curses Issue 7 (2009) specifies <EM>infocmp</EM>.  It  does  not  mention
       options for producing descriptions in <EM>termcap</EM> format.

       SVr4   <EM>infocmp</EM>   does  not  distinguish  between  absent  and  canceled
       capabilities.  It furthermore reports missing integer  capabilities  as
       <STRONG>-1</STRONG>  (its  internal  representation).  <EM>ncurses</EM> shows these as "NULL" for
       consistency with missing string capabilities.

       The <STRONG>-r</STRONG> option of  <EM>ncurses</EM>  <EM>infocmp</EM>  uses  SVr4's  notion  of  "termcap"
       capabilities.  BSD <EM>curses</EM> had a more restricted set.  To see only those
       present in 4.4BSD, use "<STRONG>-r</STRONG> <STRONG>-RBSD</STRONG>".


</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
       Although  System  V  Release  2  provided a terminfo library, it had no
       documented tool for decompiling the terminal descriptions.  Tony Hansen
       (AT&amp;T) wrote the first <STRONG>infocmp</STRONG> in early 1984, for System V Release 3.

       Eric Raymond  used  the  AT&amp;T  documentation  in  1995  to  provide  an
       equivalent  <STRONG>infocmp</STRONG>  for  <EM>ncurses</EM>.   In  addition,  he  added a few new
       features such as:

       <STRONG>o</STRONG>   the  <STRONG>-e</STRONG>  option,  to  support   <EM>fallback</EM>   (compiled-in)   terminal
           descriptions

       <STRONG>o</STRONG>   the <STRONG>-i</STRONG> option, to help with analysis

       Later,  Thomas  Dickey added the <STRONG>-x</STRONG> (user-defined capabilities) option,
       and the  <STRONG>-E</STRONG>  option  to  support  fallback  entries  with  user-defined
       capabilities.

       For a complete list, see the <EM>EXTENSIONS</EM> section.

       In  2010,  Roy  Marples  provided an <STRONG>infocmp</STRONG> program for NetBSD.  It is
       less capable than the SVr4 or <EM>ncurses</EM>  versions  (e.g.,  it  lacks  the
       sorting  options  documented in X/Open), but does include the <STRONG>-x</STRONG> option
       adapted from <EM>ncurses</EM>.
