Reading lines in a file and avoiding lines with # with Bash

Question

I tried this:

file=\"myfile\"
while read -r line
do
    [[ $line = \\#* ]] && continue
    \"address=\\$line\\127.0.0.1\"
done < \"$file\"
         


        

Answer 1

This could also be accomplished with 1 sed command:

file="myfile"

sed -i".backup" 's/^#.*$//' $file

This will modify the file in-place (creating a backup copy first), removing all lines starting with a #.
