PATHCHK(1) BSD General Commands Manual PATHCHK(1)NAMEpathchk — check pathnames
SYNOPSISpathchk [-p] pathname ...
DESCRIPTION
The pathchk utility checks whether each of the specified pathname argu‐
ments is valid or portable.
A diagnostic message is written for each argument that:
· Is longer than PATH_MAX bytes.
· Contains any component longer than NAME_MAX bytes. (The value of
NAME_MAX depends on the underlying file system.)
· Contains a directory component that is not searchable.
It is not considered an error if a pathname argument contains a nonexis‐
tent component as long as a component by that name could be created.
The options are as follows:
-p Perform portability checks on the specified pathname arguments.
Diagnostic messages will be written for each argument that:
· Is longer than _POSIX_PATH_MAX (255) bytes.
· Contains a component longer than _POSIX_NAME_MAX (14) bytes.
· Contains any character not in the portable filename character
set (that is, alphanumeric characters, ‘.’, ‘-’ and ‘_’). No
component may start with the hyphen (‘-’) character.
EXIT STATUS
The pathchk utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
Check whether the names of files in the current directory are portable to
other POSIX systems:
find . -print | xargs pathchk-p
