Not clear why there's a colon at the start; is this vim? Here's how to do it in vim:
Thanks!
I am using Vi.
I tried using the command but it did not execute. (Even tried in vim)
I tried searching for
/Mg\([24]\).\(q[np][as]\)
and it could find all the lines.
But when I search for
/Mg\([24]\).\(q[np][as][b]?\) It cannot find anything. How can I make the presence of that last charachter b optional in the substitution command?
One more question: How do I substitute in case I have some charachters in between Mg...... and W=175u like below. These in between charachters should not be disturbed.
Mg2.qns A B C L=123u W=0.175u
Mg2.qpsb DE 12 c1 L=123u W=0.175u
Mg4.qns M N O W=0.175u
Mg4.qpsb W=0.175u
