$(command) is bashism. `command` is the "pure" bourne shell form. $ posh $ echo `echo hi` hi $ echo $(echo hi) hi And likewise on dash and busybox ash, which are the other shells I have here. IIRC latest posix includes $(command) as well. -- Tzafrir Cohen | [email protected] | VIM is http://tzafrir.org.il | | a Mutt's [email protected] | | best ICQ# 16849754 | | friend -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
