captoinfo - convert a termcap description into a terminfo description
captoinfo [tic-option] [file ...]
captoinfo -V
captoinfo looks in each given text file for termcap descriptions. For
each one found, it writes an equivalent terminfo description to the
standard output stream. termcap tc capabilities are translated
directly 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 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.
captoinfo translates some obsolete, nonstandard capabilities into
standard (SVr4/XSI Curses) 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.

If the single-line capabilities occur in an entry, they are composed
into an acsc string. The double-line capabilities and GG are discarded
with a warning message.
IBM's AIX has a terminfo facility descended from SVr1 terminfo, but
which is incompatible with the SVr4 format. captoinfo translates the
following AIX extensions.
IBM XSI

ksel kslt
kbtab kcbt
font0 s0ds
font1 s1ds
font2 s2ds
font3 s3ds
Additionally, this program translates the AIX box1 capability to an
acsc string.
The HP-UX terminfo library supports two nonstandard terminfo
capabilities, meml (memory lock) and memu (memory unlock). captoinfo
discards these with a warning message.
/etc/termcap
default termcap terminal capability database
The verbose option is not identical to SVr4's. Under SVr4, instead of
following the -v with a trace level n, you repeat it n times.
X/Open Curses, Issue 7 (2009) describes tic briefly, but omits this
program. SVr4 systems provide captoinfo as a separate application from
tic.
NetBSD does not provide this application.
