toybox is a utility that combines tiny versions of many common UNIX utilities into a single, small executable.


USE flags

USE flags for sys-apps/toybox Common linux commands in a multicall binary

savedconfig Use this to restore your config from /etc/portage/savedconfig ${CATEGORY}/${PN}. Make sure your USE flags allow for appropriate dependencies


root #emerge --ask sys-apps/toybox



To view usage information use

user $toybox --help
Toybox 0.8.6 multicall binary: (see toybox --help)

usage: toybox [--long | --help | --version | [COMMAND] [ARGUMENTS...]]

With no arguments, "toybox" shows available COMMAND names. Add --long
to include suggested install path for each command, see for details.

First argument is name of a COMMAND to run, followed by any ARGUMENTS
to that command. Most toybox commands also understand:

--help          Show command help (only)
--version       Show toybox version (only)

The filename "-" means stdin/stdout, and "--" stops argument parsing.

Numerical arguments accept a single letter suffix for
kilo, mega, giga, tera, peta, and exabytes, plus an additional
"d" to indicate decimal 1000's instead of 1024.

Durations can be decimal fractions and accept minute ("m"), hour ("h"),
or day ("d") suffixes (so 0.1m = 6s).

Available functions:
