4.1 Shell Output Commands

Shell commands are run inside of a server process. This means that, unlike ‘make’, context is kept from one command to the next. Consequently, you can define a shell function in one place inside of your template and invoke it in another. You may also store values in shell variables for later reference. If you load functions from a file containing shell functions, they will remain until AutoGen exits.

If your shell script should determine that AutoGen should stop processing, the recommended method for stopping AutoGen is:

 
die "some error text"

That is a shell function added by AutoGen. It will send a SIGTERM to autogen and exit from the "persistent" shell.
