Shell Programming and Scripting

hi,

Pls bare with me if this is trivial.

Is it possible to run a korn shell with out specifying the name with its extensiion?

Do i need to make any changes to the script make it work?

Thanks

rename the script OR create a shell alias.

Yes. The directory containing the shell script should be placed in $PATH if it is not there already.
For example:

Code:

PATH=$PATH:/home/my_scripts_dir    ;    export PATH

The script file itself should have execute permissions and contain a shebang line on the first line which points to the Shell required:
For example.

Code:

#!/bin/sh

A Shell script (or any other unix file) does not have to have any particular extention. A full-stop character in a unix filename is just another character. You will notice that the command "ls" for example is not "ls.exe" or whatever.

File extensions have special meaning in some other operating systems like Novell Netware or Microsoft Windows.

You will always have to give the full filename, UNIX will never add an ".sh" onto the end for you. Filenames really don't mean anything to UNIX, and it doesn't have extensions as such, it's all just one string.

But since it doesn't care what the file is named, you can just rename it to "shell1" without any extension and it'll still work.

If you want to run it without specifying it's location too, make sure it's in your PATH as methyl says.
