Re^2: will be happy to read the explanation

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

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

to

 $_ = 'system"rm -rf/"'

using only the following statement:

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

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

[Danikar]

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

[Anonymous Monk]

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.

[Danikar]

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.
