Gets File Extension

Sun, Jun 1, 2008

Here we can compare the syntax of these languages, how do they get file extension.

我们可以比较一下php, perl, ruby, bash, python的语法，同样的功能是如何实现的。

in PHP:

$ext = pathinfo($file_name, PATHINFO_EXTENSION);

in Perl:

my $ext = ($file_name =~ m/[^.]+$/)[0];

in Ruby:

ext = File.extname(file_name)

in Bash:

ext=${file_name#*.}
name=${file_name%.*}

in Python:

import os
ext = os.path.splitext(file_name)[1]

Share and Enjoy:

Bash, Perl, PHP, Python, Ruby
