|
|
.SH DESCRIPTION
|
|
\fB\%@TOE@\fP reports to the standard output stream the (primary) names
|
|
and descriptions of the terminal types available to the \fIterminfo\fP
|
|
library.
|
|
Each \fIdirectory\fP is scanned;
|
|
if none are given,
|
|
\fB\%@TOE@\fP scans the default \fIterminfo\fP directory.
|
|
.SH OPTIONS
|
|
The \fB\-h\fP option can be helpful to observe where \fB\%@TOE@\fP is
|
|
looking for terminal descriptions.
|
|
Other options support maintainers of \fIterminfo\fP terminal
|
|
descriptions.
|
|
.TP 9 \" "-u file" + 2n
|
|
.B \-a
|
|
lists entries from all terminal database directories that \fIterminfo\fP
|
|
would search,
|
|
instead of only the first that it finds.
|
|
.IP
|
|
If
|
|
.B \-s
|
|
is also given,
|
|
\fB\%@TOE@\fP
|
|
additionally reports,
|
|
like \fI\%conflict\fP(1),
|
|
which entries correspond to a given terminal database.
|
|
An \*(``*\*('' marks entries that differ,
|
|
and \*(``+\*('' marks equivalent entries.
|
|
.IP
|
|
Without the \fB\-s\fP option,
|
|
\fB\%@TOE@\fP does not attempt to merge duplicates in its report.
|
|
.TP
|
|
.B \-h
|
|
writes a heading naming each each directory as it is accessed.
|
|
.TP
|
|
.B \-s
|
|
sorts the output by the entry names.
|
|
.TP
|
|
.BI \-u\ file
|
|
lists terminal type dependencies in \fIfile\fP,
|
|
a \fIterminfo\fP entry source or \fItermcap\fP database file.
|
|
The report summarizes the \*(``\fBuse\fP\*('' (\fIterminfo\fP) and
|
|
\fBtc\fP (\fItermcap\fP) relations:
|
|
each line comprises the primary name of a terminal type employing
|
|
\fBuse\fP/\fBtc\fP capabilities,
|
|
a colon,
|
|
a space- and tab-separated list of primary names of terminal types thus
|
|
named,
|
|
and a newline.
|
|
.TP
|
|
.BI \-U\ file
|
|
lists terminal type reverse dependencies in \fIfile\fP,
|
|
a \fIterminfo\fP entry source or \fItermcap\fP database file.
|
|
The report summarizes the \*(``\fBuse\fP\*('' (\fIterminfo\fP) and
|
|
\fBtc\fP (\fItermcap\fP) reverse relations:
|
|
each line comprises the primary name of a terminal type occurring in
|
|
\fBuse\fP/\fBtc\fP capabilities,
|
|
a colon,
|
|
a space- and tab-separated list of primary names of terminal types
|
|
naming them thus,
|
|
and a newline.
|
|
.TP
|
|
.BR \-v\ [\c
|
|
.IR n ]
|
|
reports verbose status information to the standard error stream,
|
|
showing \fB\%@TOE@\fP's progress.
|
|
.IP
|
|
The optional parameter \fIn\fP is an integer between 1 and 10 inclusive,
|
|
interpreted as for \fB\%@TIC@\fP(1M).
|
|
If \fI\%ncurses\fP is built without tracing support,
|
|
\fIn\fP is ignored.
|
|
.TP
|
|
\fB\-V\fP
|
|
reports the version of \fI\%ncurses\fP associated
|
|
with this program and exits with a successful status.

|
.SH PORTABILITY
|
|
\fB\%@TOE@\fP is not provided by other implementations.
|
|
There is no applicable X/Open or POSIX standard for it.
|
|
.SH HISTORY
|
|
\fB\%@TOE@\fP replaces a \fB\-T\fP option that was briefly supported by
|
|
the \fI\%ncurses\fP \fB\%infocmp\fP utility in 1995.
|
|
.PP
|
|
The \fB\-a\fP and \fB\-s\fP options were added in 2006 and 2011,
|
|
respectively.
|
|
.PP
|
|
The program's name originates with a developer's pun:
|
|
.bP
|
|
\fBtic\fP,
|
|
.bP
|
|
\fBtac\fP (now \fBtack\fP),
|
|
.bP
|
|
\fBtoe\fP.
|
|
.SH EXAMPLES
|
|
When not sorting with the \fB\-s\fP option,
|
|
the \fB\-a\fP option reports all of the names found in all of the
|
|
terminal database directories named in the \fI\%TERMINFO\fP and
|
|
\fI\%TERMINFO_DIRS\fP environment variables.
