infocmp -- compare or print compiled terminfo descriptions SYNOPSIS
infocmp [-1acnqux] [-A database] [-B database] [-w cols] [term ...] DESCRIPTION
The infocmp reconstructs the first available terminfo(5) definition found for term and prints the result in a terminfo(5) format. Capability types are grouped together and new types start new lines, first flags, then numbers, then strings. Capabilities are sorted by their name. If a second term is given then the capabilities are compared against each other. The following options are available: -1 Print one capability per line. -A database Use this database to load the first terminal definition. -B database Use this database to load subsequent terminal definitions. -a Include commented out capabilities. This only works if the database was compiled with the -a flag passed to tic(1). This also sets the -x flag as infocmp retains commented out capabilities as non standard. -c Print capabilities common to each definition. -n Print capabilities that do not exist in either definition. -q Make the comparison listing shorter by omitting subheadings and using - for absent capabilities, @ for canceled capabilities rather than NULL. -u Build a new terminal description for the first terminal description, using subsequent terminal descriptions. This also sets the -a flag. -w cols Limit the width to cols. -x Include non-standard capabilities. More -x only handles non-standard capabilities. This only works if the database was compiled with the -x flag passed to tic(1). ENVIRONMENT
COLUMNS Override columns returned by the output terminal. -w cols supersedes this. TERM infocmp uses the contents of the TERM environment variable if no terminal name is given on the command line. EXIT STATUS
The infocmp utility exits 0 on success, and >0 if an error occurs. SEE ALSO

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. FILES
