If I try copy it (cp /proc/locks /tmp/l or cat /proc/locks>/tmp/l) two times in succession, the result is always very different and the abnormal line (more than 8 field) are like attachment of previous message. So, if I process this file with awk the result many time is undefined ... My goal is extract the lock line of a specific process an see if this process lock a specific file and extract the offset lock. This procedure work if none of user login or logout on the server, but this condition is rare... today have check the lslk utilities, but even it, if user login/logout and work do not show the correct list: some time the result is wrong...
