The questions seem to have dried up so.....

If you have these files in your home directory...

file.c
main.c
defines.h
program.tar.gz
index.html

How can you delete the C source files and the header file only, using just one command?

..............dried up

*waits for competition*

Why make it difficult just use "rm" and delete all that shit

Because the idea isnt to "delete all that shit", just the C files and the header file without having to use the rm command 3 times in a row

im guesssing something along the lines of

rm *.c | *.h

[shn]

how do you change the # in the terminal window to $, or whatever string you want?

[leftism]

@4play Your on the right track, but thats not the right answer


@shn

I would guess that you have to change something in .bashrc?

The correct asnwer is typing PS1="$" from a terminal.

But wouldn't that mean you'd have to do that every time you logged in? If you put it in the .bashrc file it will always be $.

The correct asnwer is typing PS1="&#036;" from a terminal.

If you wanted to set the shell variable to that permanently then yes you could edit .bashrc

PS1=""
export PS1

It searches for non-alphabetic characters?

Assuming I got it right, (fingers crossed ) What command would you issue to block all incoming packets to port 80 (TCP) ?

[LSA]

iptables -A INPUT -i ppp0 -p tcp 80

Probably not right...I just read a little bit from the man page of iptables
