Different things!

here you are backslashing to avoid string-interpolation within "doublequotes"

> if( $ENV{PATH} !~ /c:\\qa\\kontor\\bin/i)

here you are backslashing to avoid special escape \commands like \k

So in your code you need 2 levels of escapes!


Do better combine 'singlequotes' and quotemeta \Q and you avoid any explicit backslashing.
