What should be the extension

[NewGuy]

Hi,
I am brand new to Unix. I want to learn about shell programming. I just started reading a book. saving the files with .sh extension and trying execute them from the shell. But it is saying "xx.sh" is not a valid command.
shell variable is assigned to '/bin/csh'.
Please help me in running the shell programs,
Thanks.

The extension isn't important. Make sure the file is executable:

chmod +x xx.sh

AND, make sure the file's in your path. If it's in the same directory you're in, try:

shell prompt -> ./xx.sh

HTH,

You also need to check that you are using the correct shell, i.e if you are running in csh and you are using korn shell scripts then you may get errors. You can tell the system what shell to use by declaring it on the first line of the script, simply put the pathe of the shell you want to use after the charecters #!
Like this: -
#!/usr/bin/ksh

this assumes ksh is in the directory /usr/bin.
