       pmlock - simple file-based mutex

SYNOPSIS         top

       $PCP_BINADM_DIR/pmlock [-v] file

DESCRIPTION         top

       pmlock attempts to acquire an exclusive lock by creating file
       with a mode of 0.

       The exit status is 0 for success, 1 for failure.

       To release the lock, unlink file.

       In the event of a failure, the -v option produces an explanatory
