Limit memory usage per script/program

When I'm testing some scripts or programs, they end up using more memory than anticipated. In that case, computer nearly halts due to swap space usage, and sometimes I have to press Magic SysRq+REISUB to reboot.

So, I was looking for a way to limit memory usage per script and found out that ulimit can limit memory. If you run it this way:

$ ulimit -v 1000000


$ scriptname

Then the new memory limit will be valid for that shell. I think changing the limit within a subshell is much more flexible and it won't interfere with your current shell ulimit settings.

note: -v 1000000 corresponds to approximately 1GB of RAM


There are 3 alternatives - vote for the best!
