Hello, For you save your changes in /etc/fstab and main.cf, you must have root priviledges. I advice you copy the content to gedit/kedit. Then sudo or su and then reopen the files with root priviledges to save.

Do you have GUI interface,if so as collo said use Gedit or other text editor

If you are (command line) using vi editor, open the file using first take a backup
(you need root access for below opertions)

cp /etc/fstab /etc/fstab_bkup

then open via

vi /etc/fstab

press 'i' you should now get something like "--INSERT--"

now edit the contents .

After editing ,Press "Esc" key

then press :x (it's colon and x)


for more info.

man vi

im a little embarased to say the

No need for that..no one knows everything in this world :)

actually i am using root priviledges,what i did was i took an old machine tht was lying around the office and used it as pilot installation to see how it all goes so its not the actuall server but im doing a test run so to speak.i was following steps i found on this site "how to forge,The Perfect Server Fedora 9 Page 4 ",so now i need to save those changes but dont know how to do so!

[clarencek]

im using the commandline so let me try tht!

[Lakshmipathi]

are you refering to

Edit /etc/fstab and add ,usrquota,grpquota to the / partition (/dev/VolGroup00/LogVol00)
vi /etc/fstab

above part?
if you want to close that file.
use Esc and : and x ,
that will close and exit from vi and you will get command line (#) again

[clarencek]

fantastic,the commandline method worked ,thanx!so tell me,is this how i save any edits in commandline?

[clarencek]

the commandline method worked wonderfully!!im relieved!so tell me is this how i save any edit sessions?also how do i delete the numerous swap files i now have due to my lack of knowledge?

[collo]

As Lakshmipathi pu it across so well. That is how you save you work under vi editor.
Note that different commandline editors have different saving methods.

I found this simple link
vi in 10 minutes - part 1

First find the files using

ls -la

Now remove required file using rm command in interactive mode.

rm -i file.txt

This will prompt you to delete or not?

if you use

rm -rf file.txt

It won't prompt you for deleting.
Beware undeleting files can't be easy in Linux,you would need file protection tool like giis.(blowing my own trumpet lol )
