Do any of you gents know if there is a converter that turns
Bo[u]rne (:-)) shell into perl? Years ago there was
commericalware (i Think) that took /bin/sh to C. Maybe Ii'm
mis-remembering. I've googled aroud and find zip, so maybe I
was in some kind of coma-zone.
At any rate, for simple unix scripts, /bin/sh (aka "a-shell", ash)
or ksh or zsh is the way to go. Simple == a few lines.
For anything grittier, perl wins any time.
(And to save thebillions of flames that perl sux because it is
hard to read (blah, blah, blah), **comment your code**. )
Other flame to /dev/null, guys.
(G)ary [[ funny, jeez ]], LOL.
