I want to use “awk” or sed to print all the lines that start with “comm=” in a file

Question

I want to use \"awk\" or \"sed\" to print all the lines that start with comm= from the file filex, Note that each line contains \"comm=somthing\"

Answer 1

For lines that start with comm=

sed -n '/^comm=/p' filex

awk '/^comm=/' filex

If comm= is anywhere in the line then

sed -n '/comm=/p' filex

awk '/comm=/' filex
