Sure you can. You just don't get an immediate response from the computer.
Type your command, hit return, and go have a cup of coffee. When you get
back your command will be executing (or at least be being echoed).

find . -name '*.txt' -exec grep "Hello World" /dev/null {} \;
is the nicest solution... it gives both on each line, to be

Unlikely. I despise emacs, but I'm betting you're running it under
X, which changes the "dead key" that would be Ctrl in a VT.
Ctrl-z is "suspend". If you do a "ps" you might see an emacs session
sitting in the background.

It's 'Ctrl-x Ctrl-c'. That means press the control key, press the 'x' key,
release it, press the 'c' key, release it, and then release the control
key.
> "Ctr-z", which is NOT listed does,...
No it doesn't. That just suspends it. Typing 'fg' will bring it back.

Subject: weird ftp problem

Netmeisters,
I have just encountered a very strange ftp problem, and I really need
to get this fixed right away. I am ftp'ing from a laptop with SuSE
Linux 6.3 installed. After I have established the connection when I
try to ls or get or anything else I get the following:
ftp> ls
500 'EPSV': command not understood
227 Entering Passive Mode (141,106,32,10,196,66)
I have not noticed this previously, although I haven't use this laptop
much before. I just changed ISP's, to Earthlink.
I've never seen anything like this before, and I really need to get
this working. Your assistance much appreciated. Please send a copy of
your response to my email address.
Thanks,
Matthew Fleming

yep, don't allow insecure connections, even ssh1 is unsafe (expoitable)...
use (open)ssh2 (there are free winclients) and be merry. thats what i'd do

I'm not familiar with F-Secure SSH, but I know that putty (on windows)
works pretty well connecting to openssh running on linux, and they're
both free. See:

Two combination keys just to exit? You're right, I am in trouble. I'm OK
with vi, I just heard so much about Emacs, including comments to the effect
that the keystrokes were easier to learn, I thought I'd give it a
try...

Oops. First time EVER I've seen a double combination key to execute a
command. I expect Emacs will not become an editor I'm fond of. :-(

It is C-x C-c, which is to be interpreted as "C-x followed by C-c", not
"or" C-c. It is listed correcly in the manual once you understand the
convention.
>"Ctr-z", which is NOT listed does, however (found via trial and error).
That doesn't exit Emacs, it just puts it in the background (iconizes it
if you're running the X version). Many programs respond to C-z that
way.

if the laptop uses a NeoMagic chipset, you *must* use the "extern_disp"
option in order to enable the video output...
Maxstation i686? is that a Maxbook? what series? they all use different
chipsets! ATI, SiS, Trident Cyber...
also, look under /usr/X11R6/lib/X11/doc for a README that corresponds to
your laptop's chipset... you may find a tip on using an external
display...
as an alternative, and final resort, download XiG's commercial server (it
has a demo function) to see if that works..

It appears that directive excludes just a file. All alternative, backing
up an entire system, goes something like this:
tar --preserve -cvf file /bin /usr /var ... (everything but /proc /mnt

I havn't used this option, so don't know what's going wrong.

No, I'm running it in console (was, anyway). Another respondent informed
me that it's a double combination keystroke to exit, Ctrl-c then -x...don't
think I'm going to like Emacs either. But I'm not really happy with vi.
I'm not a programmer. I just want an easy to use editor for creating and
modifying configuration files and simple scripts.
