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:
#!/bin/bash
or
#!/bin/ksh
as appropriate to your setup.
Question
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 linux-gnu
.
If I call following script I only get an empty line.
#!/bin/sh
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.
