I think that I shall never see
A tool as terse as s-e-d.
With slashes slung like swords in fight,
It bends the stream to sysadmin might.
A line comes in, all raw and bare–
sed tweaks it clean with zero care.
One liner's all it ever needs:
It matches, swaps, deletes, and feeds.
A s/foo/bar/ here and there,
Transforms the logs with devilish flair.
Want line three? Or just the head?
No loops required – just whisper sed.
It parses dates and tweaks bad code,
It's duct tape for your bash abode.
Yet syntax sins can make you sweat–
Escape those slashes, don't forget!
For streams that flow and must obey,
All hail the seditor's ballet.
