.SH NAME
\fB\%toe\fP \-
list table of entries of \fIterminfo\fR terminal types
.SH SYNOPSIS
.B toe
.RB [ \-ahs ]
.RB [ \-v\ \c
.RI [ n ]]
.RI [ directory
\&.\|.\|.]
.PP
.B toe
.RB [ \-u | \-U ]
.I file
.PP
.B "toe \-V"
.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 the \fB\-s\fP option is also given,
\fB\%toe\fP adds a column to the report,
showing (like \fB\%conflict\fP(1)) which entries belong 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(1).
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 FILES
.TP
.I \*d
compiled terminal description database
.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.
