How can I sort a list of words

apple
banana
orange
healthy

by the reverse of the words, the result should be

banana
orange
apple
healthy

CodePudding user response：

Use the rev utility to reverse lines characterwise. Then rev again.

$ cat input.txt | rev | sort | rev
banana
orange
apple
healthy

As pointed out by @dan, the better solution is to do rev input.txt | sort | rev.

Mostly just because it's always nice to have a chance to recall perl:

perl -nE 'push @a, scalar reverse $_  }  { print scalar reverse $_ foreach sort @a' input-file

or

perl -nE 'push @a, $_  }  { print foreach (sort { (scalar reverse $a) cmp (scalar reverse $b) } @a) ' input-file

or

perl -e 'my @a = <>; print foreach (sort { (scalar reverse $a) cmp (scalar reverse $b) } @a)'
