Writing only timing statistics output of Timer to File
I'm running long integrations on a remote server, and I'm working in terminal in a tcsh shell.
I'm looking to write ONLY the timing statistics to a file.
For example:
$time ls >timer.out
writes both the files in my current directory & the timer statistics to the file timer.out.
I only want: 0.001u 0.004s 0:00.46 0.0% 0+0k 1+1io 0pf+0w in the file.
Any help would be greatly appreciated.
