Sed: Delete Matching Lines

EasySed & Awk3-5 min
The brief

You want a clean, comment-free view of a config: every line that starts with '#' should go.

Produce /root/work/out.txt with all comment lines removed from /root/work/config.

Everything else stays exactly as it is — including blank lines, and lines that merely mention a # partway through.

What you'll do
  • Remove every line beginning with #
  • Save the remaining lines unchanged to /root/work/out.txt

Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
