time and memory limits

psmech · 02-15-2006, 05:20 PM

Hi,
Is there any easy way to run particular program and count the time it is working and watch the use of memory?
For example I want to end this program if it lasted more than 5 seconds or used more than 1MB of memory.
I wonder if it could be done only in bash...

Thanks,
Arthur

Not sure about memory usage, maybe strace has something you could use, or taking a "snapshot" of free before and after running the program. For program runtime, just use the "time" command, such as

Code:

time xterm -e firefox

Once the program has exited, it will print the time (both user and system) the application used.

Hope that helps.

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
