PATHCHK(1) FreeBSD General Commands Manual PATHCHK(1) NAME pathchk - check pathnames SYNOPSIS pathchk [-pP] pathname ... DESCRIPTION The pathchk utility checks whether each of the specified pathname arguments is valid or portable. A diagnostic message is written for each argument that: o Is longer than PATH_MAX bytes. o Contains any component longer than NAME_MAX bytes. (The value of NAME_MAX depends on the underlying file system.) o Contains a directory component that is not searchable. It is not considered an error if a pathname argument contains a nonexistent 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: o Is longer than _POSIX_PATH_MAX (255) bytes. o Contains a component longer than _POSIX_NAME_MAX (14) bytes. o Contains any character not in the portable filename character set (that is, alphanumeric characters, `.', `-' and `_'). No component may start with the hyphen (`-') character. -P In addition to the default or -p checks, write a diagnostic for each argument that: o Is empty. o Contains a component that starts with a hyphen. 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 . -exec pathchk -p -- {} + SEE ALSO getconf(1), pathconf(2), stat(2) STANDARDS The pathchk utility conforms to IEEE Std 1003.1-2001 ("POSIX.1"). HISTORY A pathchk utility appeared in FreeBSD 5.0. FreeBSD 14.1-RELEASE-p8 May 1, 2010 FreeBSD 14.1-RELEASE-p8
