Get last field using awk substr

Question

I am trying to use awk to get the name of a file given the absolute path to the file.
For example, when given the input path /home/parent/child/filena

Answer 1

If you're open to a Perl solution, here one similar to fedorqui's awk solution:

perl -F/ -lane 'print $F[-1]' input

-F/ specifies / as the field separator
$F[-1] is the last element in the @F autosplit array
