Hi friends,
This is my very first post on forum, so kindly excuse if my doubts are found too silly.
I am trying to automate a piece of routine work and this is where I am stuck at the moment-I need to grep a particular ID through a file containing many records(which start with <LRECORD> and end with </LRECORD>), and print only those records which have the matching ID.
As an example, my input file contents are as below:
Now supposing I need to print only the record containing f42, how do I do that?

I'm having problems since few days ago, and i'm not able to make it works with a simple awk+grep script (or other way to do this).
For example, i have a input file1.txt:
cat inputfile1.txt

1172051195
1172070231
1172073514

Hi all,
Is it possible for grep to output just the pattern match and not the whole line when it comes across a match? I know you can adjust the number of trailing or leading lines that are printed, but am yet to find anything that outputs just the pattern match.
