Replace a string on specific lines which match a pattren
Hi Experts,

I have a file which contains a pattern multiple times i.e. matchthispattren. If a line is matched with this pattern. I want a number in 1234567890 to 123456789 in that line. (Basically remove the last digit from that number.

Please help.

Thanks,
Varun

What have you tried to solve this problem?

Is there just one string of digits on lines with your pattern?

Does the pattern ever contain a digit?

Can you provide sample input corresponding to what you are trying to do and show us the exact corresponding output that you are trying to produce (both in CODE tags)?

What operating system are you using?

What shell are you using?
