PROGRAM:
NAME
runlock - prevent concurrent execution of a process
SYNOPSYS
runlock [ -h ]
runlock [ -d ] [ -f pathname ] [ -t timeout ] command [ args ]
DESCRIPTION
runlock tries to hold an exclusive lock while it executes a command. Subsequent execution
of runlock with the same lock, while that lock is held, will cause the new instance of
runlock to terminate with a faliure exit code. Otherwise, the exit code of the subprocess
is returned.
USAGE
-d
Debug mode; send log messages to standard error as well as to the system log.
-f pathname
Specifies the pathname of the file to use as a lock file. The default is to create
a lock file in /tmp/cronutils-$USER with the name of the command, and suffix
".pid".
-t timeout
Specifies the duration, in seconds, for runlock to wait before giving up on trying
to acquire the lock. The default is 5 seconds.
-h
Prints some basic help.
