Let the Linux history command show the execution time of the command, which machine executes the command

1. Add the following section at the end of the/etc/profile:

user_ip= ' who-u am I 2>/dev/null| awk ' {print $NF} ' |sed-e ' s/[()]//g "

Export histtimeformat= "[%F%t][' WhoAmI '][${user_ip}]"

2. Source/etc/profile

3. Execute whatever command you want,

4. Perform the history and see the results:

311 [2013-08-28 14:39:20][root][192.168.80.1] History

312 [2013-08-28 14:39:43][root][192.168.80.1] Df-h

313 [2013-08-28 14:39:45][root][192.168.80.1] Df-g

314 [2013-08-28 14:39:47][root][192.168.80.1] History

315 [2013-08-28 14:40:01][root][192.168.80.1] Ifconfig

[2013-08-28 14:44:53][root][192.168.80.1] Init 6

317 [2013-08-28 14:46:56][root][192.168.80.1] Sdfsdfsd

318 [2013-08-28 14:46:58][root][192.168.80.1] ls

319 [2013-08-28 14:47:02][root][192.168.80.1] Hostory

[2013-08-28 14:47:04][root][192.168.80.1] History

321 [2013-08-28 14:48:35][root][192.168.80.1] Cat/etc/profile

322 [2013-08-28 14:54:32][root][192.168.80.1] History

Note: 1 and 2 must be done before you can see the effect of the history. If you want to see the history of 1 months ago, and then did not do 1 and 2, this situation is not to see the desired effect.
