Question

I wrote a perl script whihc will output a list containing similar entries like below:

$var = ' whatever'

$var contains: a single quote, a space, the word whatever, single quote

actually, this is key of a hash and i want to pull the value for the same. but due to the single quotes and a space in betweene, i am not able to pull the hash key value.

So, i want to strip $var as below:

$var = whatever

meaning remove the single quote, the space and the trailing single quote.

so that I can use $var as hash key to pull the respective value.

could you guide me on a perl oneliner for the same.

thnaks.

#!/usr/bin/perl
$string = "' my string'";
print $string . "\n";
$string =~ s/'//g;
$string =~ s/^ //g;
print $string;

Output

' my string'
my string
