       infocmp - compare or print out terminfo descriptions


       infocmp [-1CDEFGIKLTUVcdegilnpqrtux]
             [-v n] [-s d| i| l| c] [-Q n] [-R subset]
             [-w width] [-A directory] [-B directory]


       infocmp  can  be  used  to  compare  a binary terminfo entry with other
       terminfo entries, rewrite a terminfo description to take  advantage  of
       the  use=  terminfo field, or print out a terminfo description from the
       binary file (term) in a variety of formats.  In all cases, the  boolean
       fields  will be printed first, followed by the numeric fields, followed
       by the string fields.

   Default Options
       If no options are specified and zero or one  termnames  are  specified,
       the -I option will be assumed.  If more than one termname is specified,
       the -d option will be assumed.

   Comparison Options [-d] [-c] [-n]
       infocmp  compares  the  terminfo  description  of  the  first  terminal
       termname  with  each  of  the descriptions given by the entries for the
       other terminal's termnames.  If a capability is defined for only one of
       the  terminals,  the  value  returned  will  depend  on the type of the
       capability: F for boolean variables, -1 for integer variables, and NULL
       for string variables.

       The  -d  option  produces  a  list of each capability that is different
       between two entries.  This option is  useful  to  show  the  difference
       between  two  entries,  created  by  different  people, for the same or
       similar terminals.

       The -c option produces a list of each capability that is common between
       two  or more entries.  Capabilities that are not set are ignored.  This
       option can be used as a quick check to see if the -u  option  is  worth

       The -n option produces a list of each capability that is in none of the
       given entries.  If no termnames are  given,  the  environment  variable
       TERM  will  be  used  for both of the termnames.  This can be used as a
       quick check to see if anything was left out of a description.

   Source Listing Options [-I] [-L] [-C] [-r]
       The -I, -L, and -C options will  produce  a  source  listing  for  each
       terminal named.

            -I   use the terminfo names
            -L   use the long C variable name listed in <term.h>
            -C   use the termcap names
            -r   when using -C, put out all capabilities in termcap form
            -K   modifies the -C option, improving BSD-compatibility.

       If  no  termnames are given, the environment variable TERM will be used
       for the terminal name.

       The source produced by the -C option may be used directly as a  termcap
       entry,  but not all parameterized strings can be changed to the termcap
       format.  infocmp 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 termcap format, you should use both
       -C  and  -r.   Normally a termcap description is limited to 1023 bytes.
       infocmp 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  -T  option.   More
       often  however,  you  must  help  the  termcap implementation, and trim
       excess whitespace (use the -0 option for that).

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

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

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

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

           terminfo                    termcap   Representative Terminals
           %p1%c                       %.        adm
           %p1%d                       %d        hp, ANSI standard, vt100
           %p1%'x'%+%c                 %+x       concept
           %i                          %iq       ANSI standard, vt100
           %p1%?%'x'%>%t%p1%'y'%+%;    %>xy      concept
           %p2 is printed before %p1   %r        hp

   Use= Option [-u]
       The -u option produces a  terminfo  source  description  of  the  first
       terminal  termname  which  is  relative  to the sum of the descriptions
       given by the entries for the other terminals termnames.  It  does  this
       by  analyzing  the differences between the first termname and the other
       termnames and producing a description with use= 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 infocmp  will  show  what
       can be done to change one description to be relative to the other.

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

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

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

       Another error that does not cause incorrect compiled  files,  but  will
       slow  down  the  compilation time, is specifying extra use= fields that
       are superfluous.  infocmp will flag any other termname use= fields that
       were not needed.

   Changing Databases [-A directory] [-B directory]
       Like   other   ncurses   utilities,  infocmp  looks  for  the  terminal
       descriptions  in  several  places.   You  can  use  the  TERMINFO   and
       TERMINFO_DIRS environment variables to override the compiled-in default
       list of places to search (see curses(3X) for details).

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

       ·   The -A option sets the location for the first termname

       ·   The -B option sets the location for the other termnames.

       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.

   Other Options
       -0   causes the fields to be printed on one line, without wrapping.

       -1   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

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

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

       -E   Dump  the  capabilities of the given terminal as tables, needed in
            the  C  initializer  for  a  TERMTYPE  structure   (the   terminal
            capability  structure in the <term.h>).  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

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

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

       -F   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 -r.

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

       -G   Display constant  literals  in  decimal  form  rather  than  their
            character equivalents.

       -g   Display  constant  character  literals  in quoted form rather than
            their decimal equivalents.

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

            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
                         RIS           full reset

                         DECPNM        normal keypad mode
                         DECANSI       enter ANSI 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 `+' (turn on) or `-' (turn off).

            An SGR0 designates an  empty  highlight  sequence  (equivalent  to

       -l   Set output format to terminfo.

       -p   Ignore padding specifications when comparing strings.

       -Q n 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

       -q   This makes the output a little shorter:

            ·   Make  the  comparison listing shorter by omitting subheadings,
                and using "-" for absent capabilities, "@" for canceled rather
                than "NULL".

            ·   Omit the "Reconstructed from" comment for source listings.

            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.

            Available  terminfo subsets are "SVr1", "Ultrix", "HP", and "AIX";
            see terminfo(5) for details.  You can also choose the subset "BSD"
            which   selects   only   capabilities   with  termcap  equivalents
            recognized by 4.4BSD.

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

            d    leave  fields  in  the  order  that  they  are  stored in the
                 terminfo database.

            i    sort by terminfo name.

            l    sort by the long C variable name.

            c    sort by the termcap name.

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

       -T   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

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

       -U   tells  infocmp  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 infocmp makes to fill in missing data.

       -V   reports the version of ncurses which was used in this program, and

       -v n prints  out  tracing  information on standard error as the program
            runs.  Higher values of n induce greater verbosity.

       -w width
            changes the output to width characters.

       -x   print  information  for  user-defined  capabilities.   These   are
            extensions  to  the  terminfo repertoire which can be loaded using
            the -x option of tic.

       The  -r  option's  notion of `termcap' capabilities is System V Release
