Re: ascii problem

The basic regex would be

s/.\^H//
[download]

This would get the inner match. Then...

while ($var =~ /.\^H/) {
  $var =~ s/.\^H//;
}
[download]

forgot the 's', sorry.

That only works if he really has two characters for backspace - "^" and "H". More likely he's got real backspaces, aka \x08 in Perl (among many ways to write that, of which ^H is not one). -sam	[reply]

If it is in a string then it isn't a backspace character. It is the characters '^' and 'H'.	[reply]

I don't know what makes you so sure. His post is ambiguous, but I take it as significant that he claims to be working on a keylogger's output. That would almost certainly have real backspaces not "^" and "H". Of course it's impossible to be sure - he could have a screen-cap of a keylogger... -sam	[reply]

Certainly the Unix utility `script` records the backspace as the single character with decimal value 8, this is what I would expect from any "keylogger" as that is the "value" of the key that was pressed. /J\	[reply] [d/l]
