EShell questions

EShell questions

[Molitor, Stephen]

1.  What's the closest thing to the Unix 'find' utility in EShell?  I'm
looking for something that will find a bunch of files, and then run a
command on them, like 'find . -name '*~' -exec rm -f {} \;'. 

2.  Is there an equivalent to xargs?

3.  How to I get help on eshell commands?  'cp --help', 'cp -h', etc. didn't
seem to work.

4.  Eshell is great, and I found the home page.  How do I get more
information on it?  Is there a mailing list?

Thanks

I believe that "find" is a separate program that should exist in your
PATH for the shell to execute. What OS are you using?  You might
probably get a port of "find" for your particular OS.

Same here.  They are separate programs.  And you have to make them
available.

If you have the 'cp' program, then these would work.

From Eshell documentation,

As mentioned above, Eshell comes preinstalled as of Emacs 21.  If
you're using Emacs 20.4 or later, or XEmacs 21, you can download the
most recent version of Eshell from

http://www.gci-net.com/users/j/johnw/Emacs/eshell.tar.gz

But nothing is mentioned about any mailing lists.

Sorry, I guess I didn't make myself clear; I dashed my post off in a hurry.

My understanding was the one of the advantages of Eshell was that was
cross-platform, and would work the same on any OS, if you restricted
yourself just to stuff implemented in Eshell.  So I was hoping to do things
like 'find', and 'xargs', without relying on OS specific stuff (or Cygwin.)
If the eshell built-in commands had help (--help), that would be nice.  If
they don't that's fine too.

However, I've already answered some of my questions.  For example, I can
replace this:

find . -name '*~' -exec rm -f {} \;

With this:

rm -f **/*~

Very cool!  I guess that's a zsh style thing, but very powerful.

Is this the best mailing list to talk about Eshell?
