Script runs when I type it into a terminal, but not when I run it from a .sh file

I wanted to run this at start-up because I like to play around with multiple DEs. When I run this script from a file it won't run Docky.

I have already changed the file permissions so that it is allowed to run as a program.

When I type exactly this into gnome-terminal it will run Docky if I am logged into gnome-classic. I wanted to run this script at startup so that Docky wouldn't start in Unity:

if [ $DESKTOP_SESSION == "gnome-classic" ] ; then docky ; fi

Any suggestions?
I tried writing something like Firefox in the same file and it will start Firefox.
So when I run the following script from a file...

cd /home/user/Desktop

mkdir ITRAN

if [ $DESKTOP_SESSION == "gnome-classic" ] ; then docky ; fi

It makes a new file on my desktop but won't run Docky even though if I simply copy the same code into a terminal window it runs...

With geirha's help, I changed the script. However, now docky launches no matter what DE I run, Unity or gnome-classic.

#!/bin/sh

if [ $DESKTOP_SESSION = "gnome-classic" ]; then

   docky

fi

I've also tried

$DESKTOP_SESSION = "gnome-classic"

$DESKTOP_SESSION = gnome-classic

"$DESKTOP_SESSION" = gnome-classic

"$DESKTOP_SESSION" = "gnome-classic"

to rule out the possibility that I had that part wrong.

The [ command does not have a == operator. Bash allows it, but dash will cringe. The correct operator to use is =. The script you posted in your question does not have a shebang, so it likely gets run by sh. So:

#!/bin/sh

mkdir -p "$HOME/Desktop/ITRAN"

if [ "$DESKTOP_SESSION" = gnome-classic ]; then

    docky

fi

Anyway, if it fails, you'll likely find the error messages in ~/.xsession-errors, so look in there for clues.
