How do I replace “\” with “//” in Perl?

Question

I want to substitute, the "\" that appears in the Windows directory link to a "/". I tried using s//\////g, but it doesn't seem to do the trick.

Answer 1

I think this should do it:`

$str =~ s{\\}{//}g; 

Answer 2

s[\\][//]g

• \ needs to be escaped in a regex
• / does not
• Avoid using / to delimit regex sections when using / in the expression itself (it makes things much more readable!)

... but you should probably use something like Path::Class.

Answer 3

First of all, using a different separator than \ will make your regex more readable.

Then you have to replace the \ with \\, or it will be used to escape the following character (a / in the regex you are using).

$link =~ s|\\|//|g;
