Maintenance Session Tuesday 18th August

The next maintenance session will be on Tuesday 18th August from 12:00 until 17:00. There will be no access to the system during this period. This will affect Shaheen I, Neser and Shaheen II. Important security updates, custom patches and several bug fixes will be applied to the XC40, which will require the whole system to be rebooted.

Tip of the Week: What command did I type before ?

History command

The “history” command will output the recently-executed commands recorded in a history list. More details about available in the man pages

Searching through the Command History ( CTRL+R )

Use the CTRL+R keys to perform a “reverse-i-search”. For example, if you wanted to use the command you used the last time you used grep, you would type:

CTRL-R then type “grep”.

What you will see in the console window is:

(reverse-i-search)`':

After you have typed what you are looking for, use the CTRL-R key combination to scroll backward through the history.

Use CTRL+R repeatedly to find every reference to the string you've entered. Once you've found the command you're looking for, use [Enter] to execute it. Alternatively, using the right or left arrow keys will place the command on an actual command-line so you can edit it.
