how to perform simple editing of a file


When my machine boots, a list of operating systems is provided and I choose which one I want to use. If I don't select anything then linux loads by default.

I want to change this so that windows loads by default. Through the help of these forums I know I need to change:

/etc/lilo.conf as root

then run

/sbin/lilo to effect the changes.

I was given a link to http://www.linuxcommand.org/ for further info. I have now read this site and it has been an excellect source for getting to know the shell. But it has not provided any info on how to edit a file and save. Could somoene please explain how to do the above steps?

Also what was meant in the above by then run /sbin/lilo to effect the changes.

For editing a file - see vi:
http://www.collaborium.org/onsite/ve...nux_guides/vi/

For running /sbin/lilo - just type it as a prompt as root and press enter.

Or, even easier, try XEmacs if you have it. It's a nice X-windows shell for Emacs, and easier to use for new users. You didn't mention your release, so I can't suggest how you'd get XEmacs. You'd probably do something like "yum install xemacs" or "apt-get xemacs."

Are you aware of the fact that the "normal" emacs has a GUI
frontend, too? No need to install xemacs which exclusively
runs in X ...

Use vi. Nice, quick and easy. No GUI (X) needed.

To open a file:

$ vi your_file_name

To edit the file: Press I.

Then navigate through the file normally and make any changes.

When complete, press ESC once.

Then, type ":wq" to save and quit.

Done.

That may be oversimplifying it a bit. On any vi I've used, you had to hit ESC everytime you wanted to move to another line ... then i again to edit that line. ... vim works as you describe.

That being said, kos147, ... Do extend the effort to gain at least rudimentary skills with vi ... once you begin to get comfortable with it switch to vim, and don't use the GUI's until you're comfortable using them in the shell. vi is different, but it's not really hard ... and it's ubiquitous on Unix type systems.

If I want to use a GUI editor, I prefer nedit ... but for things like a quick edit of your lilo.conf files, vi is the right tool. A big part of becoming proficient any any endeavor is learning the use of the right tool for the task at hand.

Also, when you're through editing {SHIFT} ZZ works just like :wq ... If you mess it up and want to start over ... :q!

Thanks for the advice everyone.

I think I will start to learn how to use VI.

In the meantime in order to make the required change is it ok to editi this file using KWrite.

Also could someone give me the command to run lilo and also which dir I should be in.

Thanks

The command to run lilo is lilo, and can be issued from anywhere
as long as you're root and it's in your path ;)

ok using: ls - l lilo.conf

I can see that the root user can read and write.
irm
and the root group can only read.

I assume because I cannot save ny chnages that I am not root user. Is there a way of confirming this?

Also how do I now modify the file?

Type "whoami" on the command line. If it says anything other than "root" (and it probably will), you need to issue the command "su" followed by your root password. Then you may edit lilo.conf in your favorite editor.

I always preferred Nano - extremely straightforward, beginner-friendly - but I have started using Vim exclusively, and I think I'll stick with that.
