hi, i have the following shellscript and it keeps telling me that Add: command not found. Can anyone explain to me whats wrong?

```nohighlight
for userName in `awk -F":" '{print $3}' passwd`
do
        while [$userName -gt 500]
        do
                echo $userName
                $count = `expr $count + 1`
                echo -n "Add $count"
        done
done

```

You need to use:  
count=`expr $count + 1`

No spaces around the the equals sign. No dollar sign in front of count when you are assigning it a value. But this doesn't explain the error you mentioned. I suspect you posted different code than you are really running. Look carefully at the those double quotes in your real code. Are you missing one?

i did delete the spaces but it still says command Add is not found 😕

```nohighlight
#!/bin/bash
#-c

#count = 0
for userName in `awk -F":" '{print $3}' passwd`
do
        while [$userName -gt 500]
        do
# echo $userName
                $count=`expr $count + 1`
                echo "Add $count"
        done
done

```
