General :: Why Seq 10 Sed Just Delete Three Lines
Jun 30, 2011Code:
[root@station3 ~]# seq 10 | sed -e '1,2d' -e '1,2d'
4
5
6
7
8
9
10
We can see that sed just deletes the first three lines. How "seq 10 | sed -e '1,2d' -e '1,2d'"works?

General :: Delete All Lines Containing A String, Plus 4 Lines Below It?
Jan 26, 2010I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)

So, I can't figure out what to do.
