I like to know what’s happening on my Linux servers. The output of the history command doesn’t include a datetime stamp by default. To rectify this open the global profile….
Add the following line to the bottom.
export HISTTIMEFORMAT="%h %d %H:%M:%S "
The output of the history command will now look something like…
997 Jun 12 11:01:55 exit 998 Jun 12 11:01:55 df -h 999 Jun 07 18:02:28 history 1000 Jun 07 18:02:37 exit 1001 Jun 12 11:01:58 history 1002 Jun 12 11:03:40 df -h 1003 Jun 12 11:03:46 history
All current entries will be defaulted to the current timestamp so it will take a little time for the output to be valid. Tested on OpenSuSE 11.2 but should be valid for many other distributions.
