Howdy All!
I have a small script called maths.sh with the following code in it:
#/usr/bin/bash
count=0
echo $count
count=$(( $count + 1 ))
echo $count
count=$(( $count + 1 ))
echo $count
count=$(( $count + 1 ))
echo $count
count=$(( $count + 1 ))
echo $count
When I run the instructions directly on the command line it works ok but
when I run the script, it fails, as you can see from the following screen
dump:
$ count=0
$ echo $count
0
$ count=$(( $count + 1 ))
$ echo $count
1
$ count=$(( $count + 1 ))
$ echo $count
2
$ count=$(( $count + 1 ))
$ echo $count
3
$ count=$(( $count + 1 ))
$ echo $count
4
$ ./math.sh
0
? 0 + 1 ?
? ? 0 + 1 ? + 1 ?
? ? ? 0 + 1 ? + 1 ? + 1 ?
? ? ? ? 0 + 1 ? + 1 ? + 1 ? + 1 ?
$
Can anyone tell me what is going wrong?
Any advice would be most appreciated!
Rob
