toe(1M)

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(1M). 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
qansi-t       QNX ansi without console writes
. . .

Use the -a and -s options together to show where each terminal description was found: --> /usr/local/ncurses/share/terminfo ----> /usr/share/terminfo
*-+-:    9term         Plan9 terminal emulator for X
*---:    Eterm         Eterm with xterm-style color support (X Window System)
*-*-:    Eterm-256color    Eterm with xterm 256-colors
*-*-:    Eterm-88color    Eterm with 88 colors
*-+-:    MtxOrb        Generic Matrix Orbital LCD display
*-+-:    MtxOrb162     16x2 Matrix Orbital LCD display
*-+-:    MtxOrb204     20x4 Matrix Orbital LCD display
*-*-:    NCR260VT300WPP    NCR 2900_260 vt300 wide mode pc+  kybd
*-+-:    aaa           ann arbor ambassador/30 lines
*-+-:    aaa+dec       ann arbor ambassador in dec vt100 mode
*-+-:    aaa+rv        ann arbor ambassador in reverse video

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).

SEE ALSO

This describes ncurses version 6.2 (patch 20200212).
