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

Comment lines can and often do begin with whitespace. Here's a bash native regex solution that handles any preceeding whitespace;

while read line; do
  [[ "$line" =~ ^[[:space:]]*# ]] && continue
  ...work with valid line...
done
