NAME
infocmp - compare or print out TERMINFO descriptions
SYNOPSIS
infocmp [-d] [-c] [-n] [-I] [-L] [-C] [-r] [-u]
[ -s d|i|l|c ] [-v] [-V] [-1] [ -w width ]
[ -A directory ] [ -B directory ] [ termname ] ...
where:
width is the output width limit in columns
directory is the path to a TERMINFO directory hierarchy
DESCRIPTION
The infocmp command can be used to compare a binary terminfo(4) entry
with other terminfo(4) entries, rewrite a terminfo(4) description to
take advantage of the use= terminfo(4) field, or print out a
terminfo(4) description from the binary file 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
If no options are specified and zero or one termnames (see term(5))
are specified, the -I option will be assumed, listing the terminfo(4)
description. If more than one termname is specified, the -d option
will be assumed, comparing the terminfo(4) descriptions.
Comparison Options [-d] [-c] [-n]
Infocmp compares the terminfo(4) description of the first terminal
termname with each of the descriptions given by the entries for the
other terminals' termnames. If a capability is defined for only one
of the terminals, the value used for the other terminal being
compared will depend on the type of the capability: F (false) for
boolean variables, -1 for integer variables, and NULL for string
variables.
-d produce a list of capabilities that are different between two
entries. With this option, you can find out what two people
did differently when creating separate entries for the same
terminal, and analyze how two similar terminals differ from
each other.
-c produce a list of capabilities that are common between the
two entries. Capabilities that are not set are ignored.
This option can be used as a quick check before using the -u
option.
-n produce a list of capabilities that are in neither entry. If
no termnames are given, the value of 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 the
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 terminfo(4) names in the listing
-L use the long C variable name listed in <term.h>
-C use the termcap(5) names
-r when using -C, put out all capabilities, not just standard
termcap(5) variables.
If no termnames are given, the value of 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(5) entry, but not all of the parameterized strings may be
changed to the termcap(5) format. Infocmp will attempt to convert
most of the parameterized information, but that which it doesn't will
be plainly marked in the output and commented out. These should be
edited by hand.
All padding information for strings will be collected together and
placed at the beginning of the string where termcap(5) expects it.
Mandatory padding (padding information with a trailing '/') will
become optional.
All termcap(5) variables no longer supported by terminfo(4), but
which are derivable from other terminfo(4) variables, will be output.
Not all terminfo(4) capabilities will be translated; only those
variables which were part of termcap(5) will normally be output.
Specifying the -r option will take off this restriction, allowing all
capabilities to be output in termcap(5) form.
Note that it is not always possible to convert a terminfo(4) string
capability into an equivalent termcap(5) format. This restriction
exists because padding is collected to the beginning of the
capability, not all capabilities are output, mandatory padding is not
supported, and termcap(5) parameter sequences were not as flexible.
Also, a subsequent conversion of the termcap(5) file back into
terminfo(4) format will not necessarily reproduce the original
terminfo(4) source.
Some common terminfo(4) parameter sequences, their termcap(5)
equivalents, and some terminal types which commonly have such
sequences, are:
terminfo(4) termcap(5) Representative Terminals
%p1%c %. adm, dg
%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 produce a terminfo(4) source description of the first
terminals' termname which is relative to the sum of the
descriptions given by the entries for the other terminals'
termnames. Infocmp 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(4) entries into a terminal's description.
Or, if two similar terminal descriptions exist, but were
coded at different times or by different people so that each
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 be printed, preceded by an at-sign (@) to delete
it, if it does not exist for the first termname, but one of the other
termname entries contains a value for it. A capability's value is
printed if the value for 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(4) compiler tic(1M) does a left-to-right scan of the
capabilities, specifying two use= entries that contain differing
values 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 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, is specifying extra use= fields that are
unnecessary. Infocmp will flag any termname use= fields that were
not needed.
Other Options [-s d|i|l|c] [-v] [-V] [-1] [-w width]
-s sort the fields within each type according to the argument
below:
d leave fields in the order that they are stored in the
terminfo(4) database.
i sort by terminfo(4) name.
l sort by the long C variable name.
c sort by the termcap(5) name.
If no -s option is given, the fields printed out will be
sorted alphabetically by the terminfo(4) 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(5) 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 and exit.
-1 cause 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 change the maximum line width to width characters.
Changing Databases [-A directory] [-B directory]
The location of the compiled terminfo(4) 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(4)
database, in /usr/share/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 feature, 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. Otherwise the
terminals would have to be named differently in a single terminfo(4)
database for a comparison to be made.
EXAMPLES
infocmp -L
Print out the terminfo(4) description of the default terminal, using
the long name for each capability. The default terminal is the one
specified by the environment variable TERM.
infocmp vt100 xterm
Compare the terminfo(4) descriptions of the VT100 terminal and the
standard X Window System terminal emulator.
infocmp -C -A /usr/opt/terminfo kterm
Convert the terminfo(4) binary file /usr/opt/terminfo/k/kterm into a
closely equivalent termcap(5) source description.

DIAGNOSTICS
malloc is out of space!
There was not enough memory available to process all the terminal
descriptions requested. Run infocmp several times, each time
including a subset of the desired termnames.
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 specification term did not contribute anything to
the final description.
Must have at least two terminal names for a comparison to be done.
The -u, -d, and -c options require at least two terminal names.
