|INFOCMP(8)||Maintenance Commands and Procedures||INFOCMP(8)|
/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 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.
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 variables.
The -I , -L , and -C options will produce a source listing for each terminal named.
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. 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 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:
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
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.
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.
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.
