I have been editing a piece of code and came across the following line which stores the name of the curent perl script. 
my $this_proc = $0 =~ /^.+\/(.+)$/ ? $1 : $0;

[download]
I do not understand how and what does the ~ do as it just seems to remove the ./ off the front off the script name.

Thanks in advance
