       infocmp - compare or print out terminfo descriptions

       /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]...

       infocmp	compares  a binary terminfo entry with other terminfo entries,
       rewrites a terminfo description to take advantage of the use=  terminfo
       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 speci‐
       fied and zero, or one termname is specified, the -I option is  assumed.
       If more than one termname is specified, the -d option is assumed.

       The  -d , -c , and -n options can be used for comparisons. infocmp com‐
       pares 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 variables.

	     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

	     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

	     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.

	     Use the terminfo names.

	     Use the long C variable name listed in < term.h >.

	     Use the termcap names. The source produced by the -C  option  may
	     be	 used  directly as a termcap entry, but not all of the parame‐
	     terized 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.

	     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

       All  termcap variables no longer supported by terminfo , but are deriv‐
       able 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 dis‐
       played in termcap form.

       Note that because padding is collected to the beginning of the capabil‐
       ity,  not all capabilities are displayed. Mandatory padding is not sup‐
       ported. 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

       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

	     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  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 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  ter‐
       minfo compiler tic does a left-to-right scan of the capabilities, spec‐
       ifying 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 con‐
       tains, 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 descrip‐

       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.

		  Sorts	 the fields within each type according to the argument

		       Leave fields in the order that they are stored  in  the
		       terminfo database.

		       Sort by terminfo name.

		       Sort by the long C variable name.

		       Sort by the termcap name.

		  If  the -s option is not given, the fields are sorted alpha‐
		  betically by the terminfo name within each type,  except  in
		  the  case of the -C or the -L options, which cause the sort‐
		  ing to be done by the termcap name or the  long  C  variable
		  name, respectively.

		  Print	 out tracing information on standard error as the pro‐
		  gram runs.

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

		  Print	 the  fields  one to a line. Otherwise, the fields are
		  printed several to a line to a maximum width of  60  charac‐

		  Changes the output to width characters.

       The  location of the compiled terminfo database is taken from the envi‐
       ronment variable TERMINFO . If the variable is not defined, or the ter‐
       minal is not found in that location, the system terminfo database, usu‐
       ally 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  ter‐
		       minal created by different people.
