Question

I need to remove backslash from an array.

use strict;
use warnings;
use Time::HiRes qw(sleep);
use Test::WWW::Selenium;
use Test::More "no_plan";
use Test::Exception; 

@array = "qwerty-uioplkjadsfcxhbdhjjkgkmnvkgmkgmkgkglmzbcd\-\dfgtg\qwerty";

i need to remove \ in the above array. i tried with @array =~ s/\\//;but i’m unable to do it.

After removing backslash from an array, an array should contain like below:

    print @array;

    output:

qwerty-uioplkjadsfcxhbdhjjkgkmnvkgmkgmkgkglmzbcd - dfgtg qwerty

how can i just remove the backslash ?

Answer 1

First of all: double quotes will interpolate, so you should write '...d\-\dfgtg\qwerty";' instead of ".."; or use q{ }.

Then there is @array =~ s/\\//; which isn’t valid syntax. I guess you wanted to write s#\\##g for @array;.

This code works:

my @array = q{qwerty-uioplkjadsfcxhbdhjjkgkmnvkgmkgmkgkglmzbcd\-\dfgtg\qwerty};
say "--> '$_'" for @array;

s#\\##g for @array;
say "--> '$_'" for @array;

The output:

--> 'qwerty-uioplkjadsfcxhbdhjjkgkmnvkgmkgmkgkglmzbcd\-\dfgtg\qwerty'
--> 'qwerty-uioplkjadsfcxhbdhjjkgkmnvkgmkgmkgkglmzbcd-dfgtgqwerty'

BTW: If you have only one element in your array, you should probably use a scalar.
