Similar tools

Googling around I discovered some similar tools (alphabetical order):

• flock: …
• getlock: Getlock is a simple command-line file locking program…
• lockrun: Run cron job with overrun protection…
• solo: is a very simple script (10 lines) that prevents a program from running more than one copy at a time…

Is FLoM really necessary? You’ll decide!
