NAME

       infocmp - compare or print out terminfo descriptions

SYNOPSIS

       /usr/bin/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

       infocmp	compares  a  binary terminfo entry with other terminfo entries, rewrites a terminfo description to take advantage of the use= ter-
       minfo field, or prints out a terminfo description from the binary file ( term ) in a variety of formats. It displays boolean fields  first,
       then  numeric  fields,  followed by the string fields. If no options are specified and zero, or one termname is specified, the -I option is
       assumed. If more than one termname is specified, the -d option is assumed.

OPTIONS

       The -d , -c , and -n options can be used for comparisons. infocmp compares the terminfo description of the  first  terminal  termname  with
       each  of the descriptions given by the entries for the other terminal's termname. 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-
       ables.

       -d    Produce  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.

       -c    Produce 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 using.

       -n    Produce  a  list of each capability that is in neither entry. If no termname is 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.

       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. 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. 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 hand.

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

       If no termname is given, the environment variable TERM will be used for the terminal name.

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

       All  termcap  variables no longer supported by terminfo , but are derivable from other terminfo variables, will be displayed.  Not all ter-
       minfo capabilities will be translated; only those variables which were part of termcap will normally be displayed. Specifying the -r option
       will take off this restriction, allowing all capabilities to be displayed in termcap form.

       Note  that  because  padding  is collected to the beginning of the capability, not all capabilities are displayed. 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  equiva-
       lent termcap format. A subsequent conversion of the termcap file back into terminfo format will not necessarily reproduce the original ter-
       minfo 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

       -u    Produce 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 differ-
	     ent 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 is displayed 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 is displayed 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 that capability.

       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
       in which the entries are given. 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, 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  original  source
       description.

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

       -s	  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 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.

       -v	  Print out tracing information on standard error as the program runs.

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

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

       -wwidth	  Changes the output to width characters.

       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/share/lib/terminfo, is used. The options  -A  and	-B
       may be used to override this location.

       -A directory    Set TERMINFO  for the first termname.

       -B directory    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.
