Find and delete everything else...
Ok, new user, relatively new to scripting and need to move to the next stage with awk or sed or both. I have been using them both at a basic level in my script.

I want to find a line, no problem, but then I want to delete everything on that line except for the word I am looking for AND the word/field next o it on the right.

Thanks in advance

As you have not given any examples, i assume the following.

Code:
sed '/is/{s/.*\(is [^ ]*\).*/\1/}' t

cat t
this is for testing.
these are other lines.

Thanks, that worked, but I had to ditch the /is/{ and }

Not sure why. Are there differences between sed on one platform to another? I'm on Solaris 10.

I understand what the majority of the statement does, but I can't work out the \1 ?

Could you tell me what that does?

Thanks.

hello,

I would suggest you can read some perl muching formulas .Anyways it goes around like this .

Code:
 perl -wlp -e 's/^.*\b?(your_word)\s(.+)\s.*$/$1 $2/' infile

Regards,
Gaurav.

Noted; once I have my head removed from this excessively long script I will take a look at the guide.

Perl is also on my list to-do!

Thanks all.
