I'd have to agree with Jonathan. You could make shell functions to wrap source and exec, and use them for files that might have changed.

Or you could put the "check-for-change and then execute" logic into a file, and have the possibly-updated file in another location. So you'd get the protection you want for just the files you do this for, without having to change every possible caller.

Hi, this is my first post here, I really want to help with some code. In this case I can't figure out why this should be built-in in bash, if you can easily calculate the md5 or sha-1 of any file on the command line?

With the rise of services like dropbox, it makes it possible for a user to store 'shared' bashrc scripts in these services.

This is a feature request to add SHA or other cryptographic hash ability as a builtin so that for example a hash can be passed to an exec or source and a message can be printed to inform the user that the script has been modified.
