help please

[nue2]

I'm new to linux. I goggled but can't find the right answer to solve my problem. hopefully you guys would be willing to help.  I'm trying to use konsole to edit, I bring up whatever i need to edit fine. Then I hit the insert so i can change the text, but every command i use to save the edited text such as ctrl-o does not work. it just comes back up with the original text. what am i doing wrong?

you might not have the correct priv's to edit the file?

try adding sudo to the start of the command your using

ie:

sudo nano file.txt
