Retrieving the execution time of a completed command

marina · #1 (**permalink**) 09-06-2005

Hello,

I am new to this forum and relatively new to unix, but hope to become an expert soon!

My question is: How can I find out the execution time of a command that has already completed execution? More specifically, I launched a Python script to populate a PostgreSQL database on Suse Linux, using "python myscript.py" (without saying "time" before launching the command). Now the script finished execution, and I want to find out how long it took. Is there a way to do that?

Thanks in advance,
Marina.

Generally, you need to know that you want this BEFORE you run the script:

Code:

time myscript.py

is how to do it.

As a second much more complex thought - if you have accounting turned on and the script ran as a special user you can use the last command to get how long that user was logged in to run the job. Not just the script, however.
