sed

• A number of years ago back a sysadmin asked me:

Should I learn sed? Would it be useful?

• I said no, sed is obsolete. "Learn Perl or Python instead."

• But it was not always so.

• When I was first offered a sysadmin job, they told me it was partly because I had sed on my resume

• 20-year-olds who knew sed were never common

• And when Perl was fresh, it had to compete with sed

• It was distributed with a s2p translator

• And in place of sed -e 's/:.*//' you could perl -lpe 's/:.*//'
