kpseaccess - Man Page
determine whether a file can be accessed
kpseaccess mode file
Exit successfully if file can be accessed with the specified mode. The mode is an optional dash (`-') followed by zero 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 read-only.
kpseaccess accepts the following options:
Print help message and exit.
Print version information and exit.
