After lines of lines i -wrongly- closed the file without saving.Is there any way to rescue that lines(because of close without saving, it is not a file yet.)

Edit : I used Text Editor and it was a text file.I opened the new file to write.

Was this a text file? Ubuntu's 'Text Editor' saves a hidden file by default, and you would need to open Nautilus, go to the directory where the text file was, and press CTRL + H to see the hidden file. – Tom Brossman Jul 3 '12 at 10:36
You should at least specify what application you had it open in. And if you edited an existing file, or tried to create a new one. In the first case (editing an existing file), some editors do auto-save to a (temporary/backup) file, but chances are small you get your "abandoned lines" back. – Izzy Jul 3 '12 at 10:36

If you are real lucky, it might still be in memory:

sudo strings /dev/mem

I used this command but there aren't my text file.There are a lot of strings but i don't understand any of them. – myildirim Jul 3 '12 at 10:42
Try adding ` | grep "some text"` to the end. Do it fast, and close all unneeded applications to preserve memory. In fact, you might want to dump all the memory to a text file by adding ` > savedMemory.txt` to the end of the command. – dotancohen Jul 3 '12 at 10:48
i changed the output to the file but there are a lot of irrelevant strings that i didn't write. – myildirim Jul 3 '12 at 10:52
Of course, that is a dump of all your memory. Try searching that file to see if any of your lost text is in it. – dotancohen Jul 3 '12 at 10:57
I can not reach any string of my file now i accept that it totally lost.But here is my new question : Can i understand that command's output's meaning ? – myildirim Jul 3 '12 at 11:02
