How can I give arguments to time command (ubuntu)
I want to get a bit more information than the standard time command gives, so I want to pass the verbose flag. info time gives as example time -v sleep 4, however when I execute that (both in bash or tcsh) I get
% time -v sleep 4
-v: Command not found.
0.000u 0.000s 0:00.00 0.0% 0+0k 0+0io 0pf+0w
What am I doing wrong?
Solution 1:
If you execute time then (even though which time will claim otherwise...) you execute the time command of the shell. That version does not accept -v. Instead, execute the proper time executable: [source]
$ /usr/bin/time -v sleep 4
That will work.
