On: Exploring Linux command-line space time

[skywal_l]

Great write up from Fabien as usual.

FYI, you can also get a lot from the `time` command right now in your shell:

   /usr/bin/time -v ls
        Command being timed: "ls"
        User time (seconds): 0.00
        System time (seconds): 0.00
        Percent of CPU this job got: 100%
        Elapsed (wall clock) time (h:mm:ss or m:ss): 0:00.00
        Average shared text size (kbytes): 0
        Average unshared data size (kbytes): 0
        Average stack size (kbytes): 0
        Average total size (kbytes): 0
        Maximum resident set size (kbytes): 2304
        Average resident set size (kbytes): 0

[andreyv → skywal_l]

Instead of "/usr/bin/time" you can also write "command time".

[darkwater → andreyv]

or its shorter form, \time
