toe

NAME

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:

MtxOrb162 16x2 Matrix Orbital LCD display

	MtxOrb204			20x4 Matrix Orbital LCD display
	MtxOrb			Generic Matrix Orbital LCD display
	qvt101+			qume qvt 101 PLUS product
	qvt119+-25			QVT 119 PLUS with 25 data lines
	qansi-g			QNX ANSI
	qvt103			qume qvt 103
	qnxw			QNX4 windows
	qansi-w			QNX ansi for windows
	qnxm			QNX4 with mouse events
	qvt203-25-w			QVT 203 PLUS with 25 by 132 columns

. . .

Use the -a and -s options together to show where each terminal description was found:

--> /usr/local/ncurses/share/terminfo
----> /usr/share/terminfo

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:

	•		tic,
	•		tac (now tack),
	•		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).
