Subject: eval vs &
Date: Thu, 9 Apr 1992 19:06:34 -0500 [thread overview]
Message-ID: <92Apr9.200644edt.2538@groucho.cs.psu.edu> (raw)
Consider this:
; x='sleep 3'
; eval $x &
16105
; x='sleep 3 &'
; eval $x
; # No pid?
/bin/sh would print the pid.
(Speaking of asynchronous processes, I kind of miss getting exit
notification and being able to find out what their exit status is ala
csh. It's not as if rc isn't doing the wait() already. Maybe when
file completion is done.... :-))
