Thanks for that.

do you know whats wrong with this...

Code:
#!/bin/sh

hour=$(date | cut -c12-13)
echo $hour

I use ksh and i get syntax error on line 3: 'hour=$' unexpected

Oh also i've tried putting hour=$(date | cut -c12-13) on the command line and it echo's 11 so it is working?
I don't think /bin/sh knows how to use $(foo). Since you are defining your shell as #!/bin/sh, perhaps it's choking on that. Try either defining your shell as #!/bin/ksh (or whatever the path is), or use back ticks (e.g., `foo`) instead.

#!/bin/ksh
hour=$(date | cut -c12-13)
echo $hour


Odd it works fine on my Slackware box under sh and ksh and on OSX under
sh/bash and zsh.

Try
hour=`date | cut -c12-13`
echo ${hour}

Actually that's not odd at all. On all GNU/Linux systems that I have seen, /bin/sh is always a link to /bin/bash. You can check it yourself on your Slackware system. And of course bash understands the $() syntax, so there you have it.

P.S. Take a look at the /bin/sh and /bin/bash files your OSX system too.
