[net.wanted.sources] Need "calls" program for shell scripts

jerryp@tektools.UUCP (Jerry Peek) (03/06/86)

I'm looking for a program that reads through a shell script and extracts the
names of all commands that the shell might run (call).

For instance, if you fed the following shell script to it:

	for foo in *
	do
		test -r $foo && pr $foo | lpr
		(echo printed $foo at `date`; ls -l $foo; echo ======) > logfile
	done

the program I'm looking for would print something like this:

	test
	pr
	lpr
	echo
	date
	ls
	echo

Anyone have such a beast?  Thanks...
