pathchk

Check the validity and portability of pathnames. More information: https://www.gnu.org/software/coreutils/manual/html_node/pathchk-invocation.html.

• Check pathnames for validity in the current system:

pathchk {{path1 path2 ...}}

• Check pathnames for validity on a wider range of POSIX compliant systems:

pathchk -p {{path1 path2 ...}}

• Check pathnames for validity on all POSIX compliant systems:

pathchk {{[-p -P|--portability]}} {{path1 path2 ...}}

• Only check for empty pathnames or leading dashes (-):

pathchk -P {{path1 path2 ...}}
