.IR path ,
.B pathchk
prints a message if any of these conditions are false:
.br
\(bu all directories in

have search (execute) permission
.br

.I path
<= the filesystem's maximum path length
.br

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

.SS OPTIONS
.TP
.I \-p, \-\-portability
Instead of performing length checks on the underlying filesystem, test
the length of the pathname and its components against the POSIX.1
minimum limits for portability.  Also check that the pathname contains
no characters not in the portable filename character set.
.PP
The long-named options can be introduced with `+' as well as `\-\-',
for compatibility with previous releases.  Eventually support for `+'
will be removed, because it is incompatible with the POSIX.2 standard.
