unpacking a (.sh) file extention.
 

I need help unpacking a file with the (.sh) extension. Any help would be appreciated. I know how to use gunzip and tar but I never came across this.

The .sh extension usually refers to a shell script which is just a plain text ASCII file. Its not compressed or packed.

To execute
sh <filename.sh>

or

./filename.sh

Use chmod to change permissions to execute if required.

To view the file use any text editor.
