kpseaccess - determine whether a file can be accessed
kpseaccess [-rwx] file
Exit successfully if file can be accessed with the specified mode. The
mode is one or more letters of rwx, where r is for readable, w is for
writable, and x is for executable.
The difference between kpseaccess and test is that the latter looks at
the permission bits, while the former checks using the access(2) system
call. This makes a difference when file systems have been mounted
kpseaccess accepts the following additional options:
--help Print help message and exit.
Print version information and exit.
