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= 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
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 ter-
minal 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 NUL for string
variables.
-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 vari-
able 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. Mandatory 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 terminfo 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. Manda-
tory padding is not supported. Because termcap strings are
not as flexible, it is not always possible to convert a ter-
minfo 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:

-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 termi-
nals' termnames. It does this by analyzing the differ-
ences between the first termname and the other term-
names 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 terminfo compiler tic does a left-to-right scan
of the capabilities, specifying two use= entries that con-
tain differing entries for the same capabilities will pro-
duce different results, depending on the order in which the
entries are given. infocmp will flag any such inconsisten-
cies 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.
