Of course "cat -n" is almost as evil as "cat -v" (-v has a
sublanguage) and doesn't work on Plan 9:
cpu% cat -n
cat: can't open -n: '-n' directory entry not found
One could use "pr -tn" instead of the little awk script, but the
difference in speed really isn't that great. Reading a cached ~2.5MB
file of ~250K lines,
cpu% time awk '{print NR, $0}' test >/dev/null
2.85u 0.13s 3.53r awk {print NR, $0} test
cpu% time pr -tn test >/dev/null
1.75u 0.13s 2.18r pr -tn test
