bash query

[dave selby]

Hi,

I am writting a bash script but am pretty rusty. This demo script
shows my problem

#!/bin/bash
read KEY
if [ $KEY = "q" ];
then
echo "a QQQQQQQQQQQQQQQ"
fi



dave at dev-machine:~$ ./test.sh
d
dave at dev-machine:~$ ./test.sh
q
a QQQQQQQQQQQQQQQ
dave at dev-machine:~$ ./test.sh

./test.sh: line 5: [: =: unary operator expected
dave at dev-machine:~$

ie how do I error catch a straight enter key being pressed without a
character first ?

Cheers

Dave
