Man page 1 : kpseaccess

kpseaccess - determine whether a file can be accessed

kpseaccess [-rwx]file

Exit successfully if filecan be accessed with the specified mode. The mode is one or more letters of rwx , where ris for readable, wis for writable, and xis for executable.

The difference between

kpseaccess and

test is that the latter looks at the permission bits, while the former checks using the

R access (2) system call. This makes a difference when file systems have been mounted read-only.

kpseaccess accepts the following additional options:

--help

    .rb Print help message and exit.

--version

    .rb Print version information and exit.
