Extract filename and extension in Bash 35 answers

#!/usr/bin/perl
use File::Spec;
use File::Basename;
$n="hai/hello/home/something/file.txt";
my $m = basename $n;
print "$m";

You don't strictly need grep for this, but if you insist, this should work:

grep -o -e "w*.w*$"

Optionally, consider the command basename:

basename hai/hello/home/something/file.txt

You can do it using sed :

$ echo hai/hello/home/something/file.txt | sed "s|.*/||g"
file.txt

or, easier, basename :

$ basename hai/hello/home/something/file.txt
file.txt
