Using grep to extract line number
I'm trying to use grep to get the line number only. This is the command I'm using:
grep -n "Content-Disposition: attachment" mbox
The output I get is:
45:Content-Disposition: attachment; filename="test.txt"
So now I just want to get the line number (45) from this output.
Can someone help me with this? Thanks
