Re^2: will be happy to read the explanation

Thanks, excellent reference--
but how does it get from a state where:

 $_ = '=]=>%-{<-|}<&|`{'
[download]

 $_ = 'system"rm -rf/"'
[download]

using only the following statement:

 
 y; -/:-@[-`{-};`-{/" -;;
[download]

Doesn't tr/// require the destination characters to be included in the mapping? I don't see any alphanumerics in there at all.

I am quite confused on how y; -/:-@[-`{-};`-{/" -;; works as well.	[reply]

Ah I figured it out. Read up on tr/// and ull get it Think about this $_ = "abc"; y/a-c/x-z/; print $_; # Prints xyz It goes off an ascii table. ` is right before a and { is right after z.	[reply]

Ah it all makes sense now. y; -/:-@[-`{-};`-{/" -;; That translates characters. So (space) thru / : thru @ [ thru ` { thru } Take that set of characters and switch it out with the corresponding character in this list ` thru { (Includs a-z) / " - Pretty nifty.	[reply]
