sed replace a setence

Question

I want to replace a the entire line in haha.txt that matches a pattern setence.

Orignal: HAHA_IP_TYPE = 1'b1 After : HAHA_IP_TYPE = 1'b0

My command is:

sed -i '/HAHA_IP_TYPE = 1'b1/HAHA_IP_TYPE = 1'b0' haha.txt

The error message it showed up are:

sed: -e expression #1, char 34: extra characters after command

Is there anyone can help me understand it? It will be a great help.

Thanks Jeffrey

You are missing an / at the end of statement. The syntax should be e.g. 's/original text/new text/' — Raman Sailopal

Use double quote since your content has single quote:

sed -i "s/HAHA_IP_TYPE = 1'b1/HAHA_IP_TYPE = 1'b0/" haha.txt
