Re: [SHELL] Detect backslash in command line argsby LanX (Saint) |

Backslash is an escape character which needs to be escaped ... you might already guess ... with a backslash. The shell doesn't act very different to double-quoted strings in Perl.
UPDATEYou have a misconception here > With MS Windows's cmd.exe shell we can force an exception if any args passed via the command line contain a backslash: the same with Unix, just > So ... if someone does perl script.pl arg\one in one of these shells, is there any way that script.pl can detect the backslash contained in that command line argument ? In your example you are not passing a backslash, just an escaped "o", which is most probably just a simple "o"¹. To be able to pass a backslash you need to double it!!!
