How do I set this up? Thanks.

A script is simply a list of instructions that you may type at the keyboard, but put in a file with a very simple header ( "#!/bin/sh" ). They are then made executable using "chmod +x script-name".

These are normally stored in a well choosen directory and are run by type their pathname at the shell prompt. They can also be executed by other agents such as cron, or at startup/shutdown.

A commonly used naming convention is they have the shell type as an extension, eg *.sh, *.ksh, *.csh etc.

Hmm.. So I should copy and paste the code from the thread above into a text editor... Upload that file to /bin.. then call that file?

There is no need to put the script on the bin directory.

- copy the text into a text file adding in the first line #!/bin/sh (or whatever your shell is)
- chmod +x filename.sh ( makes the text file executable
- then you can add the directory where the file is located to the user path, if you want.
- if you saved the file on /root then you can run it with:
/root/filename.sh <--- press enter

- voilá

Nope... I made the file and upload but when I type in "/root/fileame" I get command not found. How do I know what shell I'm using?

echo $SHELL will tell which shell are you using.

It would be very helpful if you copy the text you are trying to run as a script, maybe the problem is inside the text (like running a command that doesn't exist).

Oops.. I just noticed the link I posted earlier was wrong. I'm trying to use the script found in this thread:

My shell is bash. Does that mean I need to change the first line in the script?
