Felix Fietkau 3670f4128d busybox: lock: implement -n "Fail rather than wait" ... lock -n is similiar to flock -n. If the lock was already taken, fail with exit code = 1 and write error message to stderr. example: if ! lock -n /tmp/foo ; then echo lock exits. else echo lock was free. But is locked now. fi > lock was free. But is locked now. > lock exists. Signed-off-by: Alexander Couzens <lynxis@fe80.eu> SVN-Revision: 46836		2015-09-09 20:36:10 +00:00
