That won't work at all. You need to use test/[.

Hi Alister,
I have to collect command output and see the exit status at the same time.
Can this work with rad's suggestion?

with out eval if i use output=$(cmd) , it breaks if there exists pipe in the command like ps -ef | grep "defunct" ..

only single word commans work like vmstat etc...

One more think Alister, how to use my if condition with test ?
