Re: Re: Security?

I think the intent there was to do a tr/// and remove "unsafe" characters; e.g., |, >, <, etc. But the guy apparently had no clue what he was doing. ;)
The sub was obviously not tested; otherwise, it would be obvious that it doesn't work...

I also initially wondered whether it was meant to be a tr/// rather than a s/// but the presence of `[` in the pattern seemed to contradict that assumption. The fact that square brackets were being treated as potentially evil led me to wonder if the code had originated in a Tcl script :-)	[reply] [d/l]

Well, you may as well tell him that this sub wasted a lot of CPU cycles. ;) It compiles and it runs but it doesn't do anything useful. --perlplexer	[reply]
