toe (1) Linux Manual Page

toe – table of (terminfo) entries

Synopsis

toe [-v[n]] [-ahsuUV] file…

Description

With no options, toe lists all available terminal types by primary name with descriptions. File arguments specify the directories to be scanned; if no such arguments are given, your default terminfo directory is scanned. If you also specify the -h option, a directory header will be issued as each directory is entered.

There are other options intended for use by terminfo file maintainers:

-a

report on all of the terminal databases which ncurses would search, rather than only the first one that it finds.

If the -s is also given, toe adds a column to the report, showing (like conflict(1)) which entries which belong to a given terminal database. An "*" marks entries which differ, and "+" marks equivalent entries.

Without the -s option, toe does not attempt to merge duplicates in its report

-s

sort the output by the entry names.

-u file

says to write a report to the standard output, listing dependencies in the given terminfo/termcap source file. The report condenses the “use” relation: each line consists of the primary name of a terminal that has use capabilities, followed by a colon, followed by the whitespace-separated primary names of all terminals which occur in those use capabilities, followed by a newline

-U file

says to write a report to the standard output, listing reverse dependencies in the given terminfo/termcap source file. The report reverses the “use” relation: each line consists of the primary name of a terminal that occurs in use capabilities, followed by a colon, followed by the whitespace-separated primary names of all terminals which depend on it, followed by a newline.

-vn

specifies that (verbose) output be written to standard error, showing toe‘s progress.

The optional parameter n is a number from 1 to 10, interpreted as for tic(1). If ncurses is built without tracing support, the optional parameter is ignored.

-V

reports the version of ncurses which was used in this program, and exits.

Examples

Without sorting, the -a option reports all of the names found in all of the terminal databases found by the TERMINFO and TERMINFO_DIRS environment variables:

History

This utility is not provided by other implementations. There is no relevant X/Open or POSIX standard for toe.

The program name refers to a developer’s pun:
 .IP • 4 tic,
 .IP • 4 tac (now tack),
 .IP • 4 toe.

It replaced a -T option which was briefly supported by the ncurses infocmp utility in 1995.

The -a and -s options were added to toe several years later (2006 and 2011, respectively).
