After hearing the talk of AmigaShell and other related things.
I am wondering if any of these shells can execute my favorite
unix KSH command, namely the backtick. Let me give you an
example.

Backtick (or grave accent) will "execute a command in place"
and let the results of that command be the arguements for
your command line. For example, the unix where command finds
where a command is located in the PATH variable, while the
file command tells what type of command it is (shell script
or executable). To find out what type of command ls is I could
type:
		> where ls
		> /bin/ls
		> file /bin/ls
or I could type:
		> file `where ls`

This may not seem like much to you, but let me assure you that
it is great. With it and pipes I can do database ANDs on text files.
For example suppose I was interested in the names of all files that
have one line that says:
	Field 1: C Source
and another line that says:
	Field 2: Game

I can find these files by the command (Warning, terse unix commands
follow):

grep "Field 1: C Source" `grep "Field 2: Game" * | cut -f1 -d":"`

Is there an Amiga Shell that can do this stuff?
