Deleting a line with gawk/awk

caps_phisto · 11-05-2004, 06:27 PM

I was wondering how I would delete a line using gawk/awk.

have this command to find the line I want to delete:

Code:

 gawk '/\/dev\/sda1/ { print }' test1

I know I shouldn't be printing the line, but is ther something I can put in the braces to remove the line from the text file. I am trying to use this in a script that a non-linux user can use to finalize installaions for me while I move on to the next machine.

Thanks in advance.

Why do you need to use gawk? I just do a grep -v on the regular expression and redirect the ouput wherever you want it to go.

Oh, wow that is much easier. Thanks.
(Oh if anyone saw the post that was here for about 1 minute, taht was because I didn't read the right "-v"

)

sed would work too

sed '/searchpattern/d' filename >newfile

And just so awk doesn't fall aside ...

awk '!/hda1/ {print}' /etc/fstab

awk is absolutely awksome! :)
