 infocmp(1M)                                                     infocmp(1M)

 NAME    [Toc]    [Back]
      infocmp - compare or print out terminfo descriptions

 SYNOPSIS    [Toc]    [Back]
      infocmp [-d] [-c] [-n] [-I] [-L] [-C] [-r] [-u] [-s d|i|l|c] [-v] [-V]
      [-1] [-w width] [-A directory] [-B directory] [termname... ]

 DESCRIPTION    [Toc]    [Back]
      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    [Toc]    [Back]
      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.

      -d   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

      -c   produces a list of each capability that is common between two
           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

      -n   produces a list of each capability that is in neither entry.  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 terminf names

      -L   use the long C variable name listed in <term.h>

 infocmp(1M)                                                     infocmp(1M)

      -C   use the termcap names

      -r   when using -C, put out all capabilities in termcap form

      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 of the parameterized strings may be changed to th
      termcap format.  infocmp will attempt to convert most of the
      parameterized information, but anything not converted will be plainly
      marked in the output and commented out.  These should be edited by

      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 optional.

      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.

      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                          %i        ANSI standard, vt100
          %p1%?%'x'%>%t%p1%'y'%+%;    %>xy      concept
          %p2 is printed before %p1   %r        hp

    Use= Option [-u]
      -u      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

 infocmp(1M)                                                     infocmp(1M)

              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 description.

      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.

    Other Options [-s d|i|l|c] [-v] [-V] [-1] [-w width]
      -s   sorts the fields within each type according to the argument

           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

 infocmp(1M)                                                     infocmp(1M)

           sorting to be done by the termcap name or the long C variable
           name, respectively.

      -v   prints out tracing information on standard error as the program

      -V   prints out the version of the program in use on standard error
           and exit.

      -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 characters.

      -w   changes the output to width characters.

    Changing Databases [-A directory] [-B directory]
      The location of the compiled terminfo database is taken from the
      environment variable TERMINFO.  If the variable is not defined, or the
      terminal is not found in that location, the system terminfo database,
      usually in /usr/lib/terminfo, will be used.  The options -A and -B may
      be used to override this location.  The -A option will set TERMINFO
      for the first termname and the -B option will set TERMINFO for the
      other termnames.  With this, it is possible to compare descriptions
      for a terminal with the same name located in two different databases.
      This is useful for comparing descriptions for the same terminal
      created by different people.
