Checkout Devel::DProf for full script profiling and Benchmark for invidual code piece profiling. jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply]

Benchmark is handy. Time::HiRes is accurate - you'd need to grab time at the start and the end and subtract, or else use an interval timer. After Compline, Zaxo	[reply]

If you're on linux or unix check the man pages for `time` Dave Code On!	[reply] [d/l]

If calculating the elapsed time to the nearest second is accurate enough for you, then a simple solution is to put this line at the end of your script: `print "Script executed in ", time - $^T, " seconds";` Hope this helps. Cheers!	[reply] [d/l]

No, that is a minus sign, not an option. I'm subtracting the time the script started from the current time (in seconds). If you want minutes instead, you could simply divide that by sixty. Check time for the doco. Cheers!	[reply]

Type at a unix prompt: time perl name_of_you_prog.pl This will give you real, user and sys time.	[reply]
