Ah, don't know how I produced that result, I did try it, but I can't reproduce
it now. I probably goofed. It doesn't work with "s in the variables, though:
$ lpargs1='x"y"z'
$ lpargs2='x"y"z'
$ lpargs3='x"y"z'
$ eval wc `set | egrep \^lpargs | cut -d= -f2- | while read l; do echo \"$l\"; done`
wc: xyz: No such file or directory
wc: xyz: No such file or directory
wc: xyz: No such file or directory
0 0 0 total
$
Where'd me "s go ?
Cheers,
Rob
