Bash Question

OSTYPE not available in sh(ell) script

Currently I'm setting up a new system using the new Xubuntu trusty tahr.
I'm not very familiar with shell scripting, but I have one which needs the OSTYPE environment variable to determine what to do.

If I call

echo $OSTYPE
in the xfce-terminal I get succesfully

If I call following script I only get an empty line.

echo $OSTYPE

Am I missing something or is it maybe a problem of the new ubuntu?

On another machine of mine it works with that script. But I don't know if something was changed for that, because the system was originally not mine.

The OSTYPE environment variable is not recognized by the original Bourne shell, which is what is being invoked by the first line of your script.

Replace it with:




as appropriate to your setup.
