pathchk: Check file name validity and portability
pathchk checks validity and portability of file names. Synopsis:
pathchk [option]… name…
For each name,
pathchk prints an error message if any of
these conditions is true:
A nonexistent name is not an error, so long as a file with that name could be created under the above conditions.
The program accepts the following options. Also see Common options. Options must precede operands.
Instead of performing checks based on the underlying file system, print an error message if any of these conditions is true:
Print an error message if a file name is empty, or if it contains a component that begins with ‘-’.
Print an error message if a file name is not portable to all POSIX hosts. This option is equivalent to ‘-p -P’.
0 if all specified file names passed all checks, 1 otherwise.
