I've seen a few tutorials that have commands and parameters on multiple line, like the one below:
Code:
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
I can copy and paste this in Putty, but what if I want to manually type it? If I press return, the first line gets processed, so how do I insert a new line?

I have an older computer with Arch installed that I want to use to accomplish most of my daily tasks using the command-line (Mailgrab, IRSSI, mpg123, Elinks, Vi, etc). I realize that there are many lightweight WMs out there that support multiple monitors, but it'd be nice if I could just use Screen or something to that effect to distribute my windows across two or three displays.

I liked the idea of the "cosmos" screensaver/desktop, but wanted to add my own pictures to the application. I navigated to /usr/share/backgrounds/cosmos and tried to drag and drop. I quickly found that I did not have permission to do this.
I googled my problem and found some command line tutorials telling me to sudo cp. My problem is that I have about 30 pics that I want to move in there, and I don't think I can just move the directory, they have to be in that folder as the pictures themselves.
I don't really feel like typing the cp line multiple times with multiple randomly named image files.
Is there a way to have the command line cp all of my files from one directory to another?
I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier.
If I was searching for a single word, I can see ways to do this.
If I paste the code I'm searching for into a text file, is there a way to:

Is there any way to quickly remove multiple related packages from the command line instead of having to enter the name of every single one? I am trying to remove OpenOffice from my server running 10.04. It would work nicely if I could get a list of packages without line breaks, such as the list displayed by aptitude when upgrading. That way I could just paste the package list into the terminal. However, "aptitude search 'openoffice'" dumps a long list on many lines that cannot be used that way.

Number of title = !num!

I wrote a script with "sed" to replace !num! in this file, which is very straightforward. However, based on the !num!, I want to remove the number of "#" based on the !num! value. Is there an easy way to do that with "sed"; otherwise, i will have to write a script to loop through the file.

I have a text file and i want to grep the word "interface" and 10 lines following it. I think there was some switch like grep -A or something ?

check
try this

I want to grep each line one by one. like I want it to

and maybe write the output to a file.
eed to make a script to append a line to the bottom of multiple files (only certain files, but 100's spread over directories).Doing a find replace inside multiple files is easy, I use the followingfind /base/dir -name "*.txt" -exec perl -pi -w -e 's/FIND/REPLACE/g;' {} ;So I tried doing the followingfind /base/dir -name "*.txt" -exec echo "Append this" >> {} ;However this just appends all the text into a file called "{}". Whereas {} should be replaced with each file that's found.

I want to be able to remove the first character of a line when I highlight multiple lines in gedit. Example:

I would then highlight/select these lines, and remove the first character to make it look like this:

I'm pretty sure there is an actual shortcut for this. If there is another text editor on Linux that it would work in, it would be nice to know how to do it in that editor as well.
