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

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.
You have a misconception here

the same with Unix, just

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!!!
