pathchk(1)

     NAME
          pathchk - check whether file names are valid or portable

     SYNOPSIS
          pathchk [-p] [--portability] [--help] [--version]
          filename...

     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of pathchk.  For
          each filename, pathchk prints a message if any of these
          conditions are false:
          o all existing directories in filename have search (execute)
          permission
          o the length of filename is no larger than its filesystem's
          maximum file name length
          o the length of each component of filename corresponding to
          an existing directory name is no larger than its
          filesystem's maximum length for a file name component

          The exit status is:
          0 if all file names passed all of the tests,
          1 otherwise.

        OPTIONS
          --help
               Print a usage message on standard output and exit
               successfully.

          -p, --portability
               Instead of performing length checks on the underlying
               filesystem, test the length of each file name and its
               components against the POSIX.1 minimum limits for
               portability.  Also check that the file name contains no
               characters not in the portable filename character set.

          --version
               Print version information on standard output then exit
               successfully.
