Lock your script (against parallel execution)
Saved by uncleflo on February 8th, 2017.
Sometimes there's a need to ensure only one copy of a script runs, i.e prevent two or more copies running simultaneously. Imagine an important cronjob doing something very important, which will fail or corrupt data if two copies of the called program were to run at the same time. To prevent this, a form of MUTEX (mutual exclusion) lock is needed. The basic procedure is simple: The script checks if a specific condition (locking) is present at startup, if yes, it's locked - the scipt doesn't start. This article describes locking with common UNIX® tools. There are other special locking tools available, But they're not standardized, or worse yet, you can't be sure they're present when you want to run your scripts. A tool designed for specifically for this purpose does the job much better than general purpose code.
