Linux time Command

Posted bybillb

In testing the gnuCOBOL program yesterday I used time as I usually do…

time ./gnuPrime

This produced at the end…

real 0m0.193s
user 0m0.146s
sys 0m0.000s

However I found another formatted, way (the leading backslash is required, for some reason)…

\time -f "Program: %C\nTotal time: %E\nUser Mode (s) %U\nKernel Mode (s) %S\nCPU: %P" ./gnuPrime

This produced…

Program: ./gnuPrime
Total time: 0:00.20
User Mode (s) 0.13
Kernel Mode (s) 0.00
CPU: 71%
