INFOCMP(8V)                                                        INFOCMP(8V)

       infocmp - compare or print out terminfo descriptions

       infocmp [ -cdnILCruvV1 ] [ -sd ] [ -si ] [ -sl ] [ -sc ] [ -w width ]
     [-A directory ] [-B directory ] [ termname ...]

       /usr/5bin/infocmp arguments

       Note: arguments to /usr/5bin/infocmp are the same as those for infocmp,

       The System V version of this command is available  with  the  System  V
       software  installation  option.   Refer  to  for  information on how to
       install optional software.

       infocmp compares  a  binary  terminfo(5V)  entry  with  other  terminfo
       entries,  rewrites a terminfo description to take advantage of the use=
       field, or prints out a  terminfo  description  from  the  corresponding
       binary file in a variety of formats.  It displays boolean fields first,
       then numeric fields, then string fields.

       It can also convert a terminfo entry to a termcap(5) entry; the -C flag
       causes  infocmp to perform this conversion.  Some termcap variables are
       not supported by terminfo, but those that can be derived from  terminfo
       variables  are displayed.  Not all terminfo capabilities are translated
       either; only those that are allowed in a  termcap  entry  are  normally
       displayed.   Specifying  the  -r  option  eliminates  this restriction,
       allowing all capabilities to be displayed in termcap form.

       Because padding is collected at the beginning of a capability, not  all
       capabilities  are  displayed.  Since mandatory padding is not supported
       by terminfo and termcap strings are not as flexible, it is  not  always
       possible  to  convert  a  terminfo string capability into an equivalent
       working termcap capability.  Also, a subsequent conversion of the term-
       cap  file  back into terminfo format will not necessarily reproduce the
       original source; infocmp attempts to convert parameterized strings, and
       comments out those that it can not.

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

       center ;  lB  lB  lB  .   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

       If no termname arguments are given, the environment  variable  TERM  is
       used for all expected termname arguments.

   Default Options
       If  no  options are specified and either zero or one termname is speci-
       fied, the -I option is assumed to be  in  effect.   If  more  than  one
       termname is specified, the -d option is assumed.

   Comparison Options
       infocmp  compares  the  description of the first terminal termname with
       each of the descriptions for terminals listed  in  subsequent  termname
       arguments.   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 vari-

       -c     Produce a list of capabilities common to both entries.  Capabil-
              ities  that are not set are ignored.  This option can be used as
              a quick check to see if the -u option is worth using.

       -d     Produce a list of capabilities that differ between descriptions.

       -n     Produce a list of capabilities in neither entry.

   Source Listing Options
       The -I, -L, and -C options produce a source listing for  each  terminal

       -I     Use the terminfo names.

       -L     Use the long C variable name listed in <&lt;term.h>&gt;.

       -C     Display  only  those capabilities that have termcap equivalents,
              using the termcap names and  displaying  them  in  termcap  form
              whenever possible.

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

       -r     When using -C, display all capabilities, not just those capabil-
              ities that have termcap equivalents.

       -u     Produce a terminfo source description for the first named termi-
              nal which is relative to the descriptions given by  the  entries
              for  all  terminals  named  subsequently on the command line, by
              analyzing the differences between them, and producing a descrip-
              tion  with use= fields for the other terminals.  In this manner,
              it is possible to retrofit generic terminfo entries into a  ter-
              minal'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

              A  capability  is  displayed with an at-sign (@) if it no longer
              exists in the first terminal, but  one  of  the  other  terminal
              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 has a different value for that capability.

              The order of the other termname entries is  significant.   Since
              the  terminfo  compiler tic(8V) 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  in  which  they  are  given.
              infocmp   flags  any  such  inconsistencies  between  the  other
              termname entries as they are found.

              Alternatively, specifying a capability after a use=  entry  that
              contains  it, 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 origi-

              Specifying superfluous use= slows down the  comparison,  but  is
              not fatal; infocmp flags superfluous use= fields.

   Sorting Options
       -sd    Sort  fields  in  the order that they are stored in the terminfo

       -si    Sort fields by terminfo name.

       -sl    Sort fields by the long C variable name.

       -sc    Sort fields by the termcap name.

              If no sorting option is given, fields are 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.

   Changing Databases
       The  location of the compiled terminfo database is taken from the envi-
       ronment variable TERMINFO.  If the variable is not defined, or  if  the
       terminal  is  not found in that location, the system terminfo database,
       usually in /usr/share/lib/terminfo, is used.  The options -A and -B may
       be  used to override this location.  With these options, 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.

       -A     Set TERMINFO for the first termname argument.

       -B     Set TERMINFO for the remaining termname arguments.

   Other Options
       -v     Print out tracing information on the standard error.

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

       -1     Print  fields  out one to a line.  Otherwise, fields are printed
              several to a line to a maximum width of 60 characters.

       -w width
              Change the output to width characters.

       malloc is out of space!
              There was not enough memory available to process all the  termi-
              nal  descriptions  requested.   Run  infocmp  in several smaller
              stages (with fewer termname arguments).

       use= order dependency found:
              A value specified in one  relative  terminal  specification  was
              different from that in another relative terminal specification.

       `use=term' did not add anything to the description.
              A  relative  terminal  name  did  not contribute anything to the
              final description.

       must have at least two terminal names for a comparision to be done.
              The -u, -d and -c options require at least two terminal names.
