Hello. I stumbled over a bug in the MUA i maintain, and when checking against what shells do with lonely unary ! i then came to this:
#?0|kent:tmp$ dash -c 'if [ ! ! hey ]; then echo du; fi' du #?0|kent:tmp$ bash -c 'if [ ! ! hey ]; then echo du; fi' bash: line 1: [: too many arguments #?0|kent:tmp$ busybox.static sh -c 'if [ ! ! hey ]; then echo du; fi' du (The single ! that my MUA bails on seems to be handled identically by shells.) --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
