linuxcnc_check_ini [-e] [-h] INIfile

The linuxcnc_check_ini program is used to verify the LinuxCNC primary configuration. It takes the specified INIfile and performs a set of sanity checks on the variables in various sections.

This program is called automatically from linuxcnc(1) as to warn the user of problems that may exist in the configuration. The tests are not exhaustive and linuxcnc_check_ini does not protect your machine or hardware. It merely ensures some basic consistency in the configuration setup. You must not rely on passing the linuxcnc_check_ini tests to have a functional machine.

The exit value is 0 (zero) when no errors are detected and the program runs successfully.

The exit value is 1 (one) if any errors are detected. Additionally, if the --error option was specified, then any detected warnings also cause the exit value be 1 (one).

The exit value is 2 (two) in case of any other problem.
