Deleting a line from a file matching criteria

to line regular expression linux delete package sed gentoo keywords use mask portage emerge sync masking accept_keywords by chrelad on Aug 13, 2008 2 Comments
I was messing around trying to figure out an easier way to remove entries from my /etc/portage/package.keywords file without having to drop into VI all the time and came up with this. You can put this into a bash script to make things alot easier on yourself if you are constantly altering your mask/use/keywords files in Gentoo.

sed -i '/x11-wm\/compiz/d' /etc/portage/package.keywords


The above example will remove any line that matches the regular expression x11-wm/compiz and edit the file in place "-i".

Compressing a directory with rar on Linux

to shell cmd command line unix linux commandline terminal recursive base directory rar rarring archive archiving compress compression compressing based recursion by chrelad on Dec 12, 2007
I've been struggling to get this to work for so long that when I finally got it going I had to throw it up here so I wouldn't lose it.
rar a -m5 -R output.rar /etc/

This will create a max compression (not taking into account dictionary sizes and the like) archive of the entire etc directory.

Disconnect Windows 2000 RDP session from command line

to remote windows command line console terminal desktop session query dos win 2000 2k rdp protocol disconnect connect active tsdiscon by chrelad on Nov 16, 2007
I use SSH to gain access to my Windows 2000 command line, so that will be reflected in the below steps.


Step #1: Connect to the server if you are not sitting at it
ssh username@win2000server -i privatekey

Step #2: Find out which sessions are currently active
query session

 SESSIONNAME       USERNAME                 ID  STATE   TYPE        DEVICE
>console                                     0  Conn    wdcon
 rdp-tcp                                 65536  Listen  rdpwd
 rdp-tcp#7         fakeuser                  1  Active  rdpwd

Step #3: We want to kill the connection with an ID of 1 (we can tell by the username and that it is active)
tsdiscon 1 /v

Disconnecting sessionID 1 from sessionname RDP-Tcp#7

That's it :) Easy eh?
