Grep in Bash Without the grep

We don’t need no stinking grep. Here’s an example of “grepping” for everything in the current direction that begins with RE:

while IFS= read -r line; do
  [[ $line =~ ^RE ]] && echo "$line"
done < <(ls -1)

You can easily throw this into a function and never need a sub-process ever again for this kind of stuff.

#bash #scripting #tips #grep
