executing a variable assignment in a string
I'm using whatever the scripting is in this copy of busybox ! So not the full boxed set sometimes.


If I do

cmd="echo fred"
$cmd

the system prints "fred"

if I do

cmd="fred=9"
$cmd

it barfs.

Is there a simple way to put a varabble assignment in a string and execute it?

Try:

Code:
cmd="fred=999"
eval $cmd
echo $fred
