captoinfo(1M) User commands captoinfo(1M)
captoinfo - convert a termcap description into a terminfo
description
captoinfo [tic-option] [file ...]
captoinfo -V
captoinfo translates terminal descriptions. It looks in each
given text file for termcap entries and, for each one found,
writes an equivalent terminfo description to the standard output
stream. termcap tc capabilities translate to terminfo “use”
capabilities.
If no files are specified, captoinfo interprets the content of the
environment variable TERMCAP as a file name, and extracts only the
entry for the terminal type named in the environment variable TERM
from it. If the environment variable TERMCAP is not set,
captoinfo reads /etc/termcap.
This utility is implemented as a link to tic(1M), with the
latter's -I option implied. You can use other tic options such as
-1, -f, -v, -w, and -x. The -V option reports the version of
ncurses associated with this program and exits with a successful
status.
Translations from Nonstandard Capabilities
captoinfo translates some obsolete, nonstandard capabilities into
standard terminfo capabilities. It issues a diagnostic to the
standard error stream for each, inviting the user to check that it
has not mistakenly translated an unknown or mistyped capability
name.

XENIX termcap had a set of extension capabilities, corresponding
to box drawing characters of CCSID (“code page”) 437, as follows.

captoinfo composes single-line box-drawing capabilities into a
terminfo acs_chars (acsc) string capability, and discards GG and
double-line capabilities with a warning diagnostic.
AIX has a terminfo facility descended from SVr2 terminfo, but
which is incompatible with the SVr4 format. captoinfo translates
the following AIX extensions.

It furthermore translates the AIX box1 capability to an acs_chars
(acsc) string capability.
The HP-UX terminfo library supports two nonstandard terminfo
capabilities: memory_lock (meml) and memory_unlock (memu).
captoinfo discards these with a warning message.
/etc/termcap

This command is an SVr4 curses and ncurses extension.
X/Open Curses Issue 7 (2009) does not specify this command.
SVr4 systems provide captoinfo as a separate application from tic.
Its -v option does not accept a trace level argument n; repeat -v
n times instead.
NetBSD does not provide this application.
