CAPTOINFO(1M) CAPTOINFO(1M)
NAME
captoinfo - convert a termcap description into a terminfo
description
SYNOPSIS
captoinfo [-v ...] [-V] [-1] [-w width] file ...
DESCRIPTION
captoinfo looks in file for termcap descriptions. For each
one found, an equivalent terminfo(4) description is written
to standard output, along with any comments found. A
description which is expressed as relative to another
description (as specified in the termcap tc= field) will be
reduced to the minimum superset before being output.
If no file is given, then the environment variable TERMCAP
is used for the filename or entry. If TERMCAP is a full
pathname to a file, only the terminal whose name is
specified in the environment variable TERM is extracted from
that file. If the environment variable TERMCAP is not set,
then the file /etc/termcap is read.
-v print out tracing information on standard error as
the program runs. Specifying additional -v
options will cause more detailed information to be
printed.
-V print out the version of the program in use on
standard error and exit.
-1 cause the fields to print 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 output to width characters.
FILES
/usr/lib/terminfo/?/* compiled terminal description database
CAVEATS
Certain termcap defaults are assumed to be true. For
example, the bell character (terminfo bel) is assumed to be
^G. The linefeed capability (termcap nl) is assumed to be
the same for both cursor_down and scroll_forward (terminfo
cud1 and ind, respectively.) Padding information is assumed
to belong at the end of the string.
The algorithm used to expand parameterized information for
termcap fields such as cursor_position (termcap cm, terminfo
cup) will sometimes produce a string which, though
technically correct, may not be optimal. In particular, the
rarely used termcap operation %n will produce strings that

are especially long. Most occurrences of these non-optimal
strings will be flagged with a warning message and may need
to be recoded by hand.
The short two-letter name at the beginning of the list of
names in a termcap entry, a hold-over from an earlier
version of the UNIX system, has been removed.

The termcap description had an entry for cc whose
type was not boolean, numeric or string.

TERM=term: cap cc (info ii) is NULL: REMOVED
The termcap code was specified as a null string.
The correct way to cancel an entry is with an '@',
as in ':bs@:'. Giving a null string could cause
incorrect assumptions to be made by the software
which uses termcap or terminfo.

NOTES
captoinfo should be used to convert termcap entries to
terminfo(4) entries because the termcap database (from
earlier versions of UNIX System V) may not be supplied in
future releases.
