infocmp(1M)                                                          infocmp(1M)

       infocmp - compare or print out terminfo descriptions

       infocmp [-1CEFGILTUVcdegilnpqrtux]
             [-v n] [-s d| i| l| c] [-R subset]
             [-w width] [-A directory] [-B directory]

       infocmp can be used to compare a binary terminfo entry with other
       terminfo entries, rewrite a terminfo description to take advantage of the
       use= terminfo field, or print out a terminfo description from the binary
       file (term) 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 are specified, the
       -I option will be assumed.  If more than one termname is specified, the
       -d option will be assumed.

   Comparison Options [-d] [-c] [-n]
       infocmp compares the terminfo description of the first terminal termname
       with each of the descriptions given by the entries for the other
       terminal's termnames.  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

       The -d option produces 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

       The -c option produces 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.

       The -n option produces a list of each capability that is in neither
       entry.  If no termnames are 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.

   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 names
             -L   use the long C variable name listed in <term.h>
             -C   use the termcap names
             -r   when using -C, put out all capabilities in termcap form

       If no termnames are given, 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
       entry, but not all parameterized strings can be changed to the termcap
       format.  infocmp will attempt to convert most of the parameterized
       information, and anything not converted 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 expects it.  Mandatory
       padding (padding information with a trailing '/') will become optional.

       All termcap variables no longer supported by terminfo, but which are
       derivable from other terminfo variables, will be output.  Not all
       terminfo capabilities will be translated; only those variables which were
       part of termcap will normally be output.  Specifying the -r option will
       take off this restriction, allowing all capabilities to be output in
       termcap form.

       Note that because padding is collected to the beginning of the
       capability, not all capabilities are output.  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

       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                          %iq       ANSI standard, vt100
            %p1%?%'x'%>%t%p1%'y'%+%;    %>xy      concept
            %p2 is printed before %p1   %r        hp

   Use= Option [-u]
       The -u option produces 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 will get printed 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 gets printed 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 the capability than that in the first termname.

       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 that
       the entries are given in.  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 time, is specifying extra use= fields that are
       superfluous.  infocmp will flag any other termname use= fields that were
       not needed.

   Changing Databases [-A directory] [-B directory]
       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, in
       /usr/share/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, 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.

   Other Options
       -1   causes 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

       -a   tells infocmp to retain commented-out capabilities rather than
            discarding them.  Capabilities are commented by prefixing them with
            a period.

       -E   Dump the capabilities of the given terminal as tables, needed in the
            C initializer for a TERMTYPE structure (the terminal capability
            structure in the <term.h>).  This option is useful for preparing
            versions of the curses library hardwired for a given terminal type.
            The tables are all declared static, and are named according to the
            type and the name of the corresponding terminal entry.

            Before ncurses 5.0, the split between the -e and -E options was not
            needed; but support for extended names required making the arrays of
            terminal capabilities separate from the TERMTYPE structure.

       -e   Dump the capabilities of the given terminal as a C initializer for a
            TERMTYPE structure (the terminal capability structure in the
            <term.h>).  This option is useful for preparing versions of the
            curses library hardwired for a given terminal type.

       -F   compare terminfo files.  This assumes that two following arguments
            are filenames.  The files are searched for pairwise matches between
            entries, with two entries considered to match if any of their names
            do.  The report printed to standard output lists entries with no
            matches in the other file, and entries with more than one match.
            For entries with exactly one match it includes a difference report.
            Normally, to reduce the volume of the report, use references are not
            resolved before looking for differences, but resolution can be
            forced by also specifying -r.

       -f   Display complex terminfo strings which contain if/then/else/endif
            expressions indented for readability.

       -G   Display constant literals in decimal form rather than their
            character equivalents.

       -g   Display constant character literals in quoted form rather than their
            decimal equivalents.

       -i   Analyze the initialization (is1, is2, is3), and reset (rs1, rs2,
            rs3), strings in the entry.  For each string, the code tries to
            analyze it into actions in terms of the other capabilities in the
            entry, certain X3.64/ISO 6429/ECMA-48 capabilities, and certain DEC
            VT-series private modes (the set of recognized special sequences has
            been selected for completeness over the existing terminfo database).
            Each report line consists of the capability name, followed by a
            colon and space, followed by a printable expansion of the capability
            string with sections matching recognized actions translated into
            {}-bracketed descriptions.  Here is a list of the DEC/ANSI special
            sequences recognized: i.

            It also recognizes a SGR action corresponding to ANSI/ISO 6429/ECMA
            Set Graphics Rendition, with the values NORMAL, BOLD, UNDERLINE,
            BLINK, and REVERSE.  All but NORMAL may be prefixed with `+' (turn
            on) or `-' (turn off).

       An SGR0 designates an empty highlight sequence (equivalent to

       -l   Set output format to terminfo.

       -p   Ignore padding specifications when comparing strings.

       -q   Make the comparison listing shorter by omitting subheadings, and
            using "-" for absent capabilities, "@" for canceled rather than

            Restrict output to a given subset.  This option is for use with
            archaic versions of terminfo like those on SVr1, Ultrix, or HP/UX
            that do not support the full set of SVR4/XSI Curses terminfo; and
            variants such as AIX that have their own extensions incompatible
            with SVr4/XSI.  Available terminfo subsets are "SVr1", "Ultrix",
            "HP", and "AIX"; see terminfo(5) for details.  You can also choose
            the subset "BSD" which selects only capabilities with termcap
            equivalents recognized by 4.4BSD.

       -s [d|i|l|c]
            The -s option sorts the fields within each type according to the
            argument below:

            d    leave fields in the order that they are stored in the terminfo

            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 printed out will be 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.

       -T   eliminates size-restrictions on the generated text.  This is mainly
            useful for testing and analysis, since the compiled descriptions are
            limited (e.g., 1023 for termcap, 4096 for terminfo).

       -t   tells tic to discard commented-out capabilities.  Normally when
            translating from terminfo to termcap, untranslatable capabilities
            are commented-out.

       -U   tells infocmp to not post-process the data after parsing the source
            file.  This feature helps when comparing the actual contents of two
            source files, since it excludes the inferences that infocmp makes to
            fill in missing data.

       -V   reports the version of ncurses which was used in this program, and

       -v n prints out tracing information on standard error as the program
            runs.  Higher values of n induce greater verbosity.

       -w width
            changes the output to width characters.

       -x   print information for user-defined capabilities.  These are
            extensions to the terminfo repertoire which can be loaded using the
            -x option of tic.

       /usr/share/terminfo Compiled terminal description database.

       The -E, -F, -G, -R, -T, -V, -a, -e, -f, -g, -i, -l, -p, -q and -t options
       are not supported in SVr4 curses.

       The -r option's notion of `termcap' capabilities is System V Release 4's.
       Actual BSD curses versions will have a more restricted set.  To see only
       the 4.4BSD set, use -r -RBSD.

       The -F option of infocmp(1M) should be a toe(1M) mode.

       captoinfo(1M), infotocap(1M), tic(1M), toe(1M), curses(3X), terminfo(5).

       This describes ncurses version 5.7 (patch 20081102).
