NAME

toe - list table of entries of terminfo terminal types

SYNOPSIS

toe [-ahs] [-v [n]] [directory ...]

toe [-u|-U] file

toe -V

DESCRIPTION

toe reports to the standard output stream the (primary) names and descriptions of the terminal types available to the terminfo library. Each directory is scanned; if none are given, toe scans the default terminfo directory.

OPTIONS

The -h option can be helpful to observe where toe is looking for terminal descriptions. Other options support maintainers of terminfo terminal descriptions.

-a: lists entries from all terminal database directories that terminfo would search, instead of only the first that it finds.
: If -s is also given, toe additionally reports, like conflict(1), which entries correspond to a given terminal database. An "*" marks entries that differ, and "+" marks equivalent entries.
: Without the -s option, toe does not attempt to merge duplicates in its report.
-h: writes a heading naming each directory as it is accessed.
-s: sorts the output by the entry names.
-u file: lists terminal type dependencies in file, a terminfo entry source or termcap database file. The report summarizes the "use" (terminfo) and tc (termcap) relations: each line comprises the primary name of a terminal type employing use/tc capabilities, a colon, a spac- and ta-separated list of primary names of terminal types thus named, and a newline.
-U file: lists terminal type reverse dependencies in file, a terminfo entry source or termcap database file. The report summarizes the "use" (terminfo) and tc (termcap) reverse relations: each line comprises the primary name of a terminal type occurring in use/tc capabilities, a colon, a spac- and ta-separated list of primary names of terminal types naming them thus, and a newline.
-v [: n] reports verbose status information to the standard error stream, showing toe's progress.
: The optional parameter n is an integer between 1 and 10 inclusive, interpreted as for tic(1M). If ncurses is built without tracing support, n is ignored.
-V: reports the version of ncurses associated with this program and exits with a successful status.

FILES

/usr/share/terminfo: compiled terminal description database

PORTABILITY

toe is not provided by other implementations. There is no applicable X/Open or POSIX standard for it.

HISTORY

toe replaces a -T option that was briefly supported by the ncurses infocmp utility in 1995.

The -a and -s options were added in 2006 and 2011, respectively.

The program's name originates with a developer's pun:
.IP * 4 tic,
.IP * 4 tac (now tack),
.IP * 4 toe.

EXAMPLES

When not sorting with the -s option, the -a option reports all of the names found in all of the terminal database directories named in the TERMINFO and TERMINFO_DIRS environment variables.
