A collection of core tools for a POSIX-compatible operating system.
Each "one-shot" tool is a single C file under src/ and can be compiled with the following:
c99 -o $tool -D_POSIX_C_SOURCE=200809L src/$tool.c
More complex tools may have several files under one directory:
c99 -o $tool -D_POSIX_C_SOURCE=200809L -Isrc/$tool/ src/$tool/*.c
To enable optional XSI support, use
-D_XOPEN_SOURCE=700 instead of
Alternatively, you can compile all of the tools with meson:
meson . build ninja -C build
This is recommended for distro packagers. Various options are available when building with meson via meson_options.txt.
Build with meson and run
ninja -C build test to run POSIX conformance tests
Some conformance tests require Linux to be run, and will be skipped on other
systems. These tests generally require some non-portable behavior to verify the
behavior of some commands; for example the
nice tests will inspect
verify its behavior. Unsupported systems will skip these tests.
Additional tests may be skipped if certain external environment variables are not provided. To run all supported tests for your system, set the following variables in your environment:
ARCHto the value expected to be printed by
ESCALATEto the name of a command which will run an arbitrary program as the system administrator, such as
ctools includes POSIX.1-2017 base utilities, but does not support any POSIX.1-2017 option groups, with the exception of XSI support where relevant to POSIX base utilities (optional). See the STATUS file for a summary of utilities defined by POSIX and their status for inclusion in ctools.
A shell is not provided. mrsh is recommended for this purpose.
