Hello,
I have a file that looks like this:
num11 num12 num13 word1
num21 num22 num23 word2
num31 num32 num33 word3
.
.
.
I would like to search for the lines that contain a given number, but I need to narrow the search only to the first field, that means that the number has to be here:
num11
num21
num31
.
.
.
can I do it with grep? Or is there another possibility?
Thank you,
Shira.
