sed or awk ???

MikeL_4 — Thu, 06 Feb 2003 20:39:23 GMT

Is there a way within sed and/or awk, (or any other command for that matter) to print certain lines within a file ??
Say in myfile I want to list lines 20 through 23 of the file only ??

Thanks

Hi,

Here is one way to do it in Perl:

perl -ne 'print unless (($.<20) or ($.>23));' filename

Hi (again):

...and if you like 'awk':

# awk 'NR >=20 && NR <= 23' filename

Regards!

awk '
NR > 19 {print;}
NR > 23 {exit;)
'

In unix there is always more than one way to do any particular job. Others have contributed sed and awk scripts. Here's another: head -23 myfile|tail -3. Try it.

In the header of each post, you see a dropdown box. Click it, and choose the appropriate amount for each post. 10 = best answer, it solved my problem, 0 = thanks, but it didn't help at all.

When youve done all, hit the (-> SUBMIT) button at the left bottom

Enjoy, have FUN! H.Merijn
