I just modified the grub file in 10.10 in order to see what the text line boot is like. Well now I want to go back, but when I try to gedit /etc/default/grub it gives an error that he couldn't display. How can I edit the file to go back to gnome??? I am on macbookpro 6.2 tripleboot Mac OS 10.6, Win7 and Ubuntu 10.10.
im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.
echo $(ps aux) >>out
The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

Was wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.
a sed command to add a text before line number in text file? I have text file with 500 lines, and i want to add 3 more lines with text after line 300, OR before line 302, isn't no problem.

I have a file which a number at the end of each line. I need to change this number in the file to be correct, i.e. each time the number is 9 it needs to be 1, each time it is 233 it needs to be 2, etc... There is no pattern to the numbers currently in the list other than the same number appears only in a single line/group of lines, not throughout the file, but the replacements need to be sequential (but can be repeated an arbitrary number of times).

I am using Ubuntu and looking for a good editor to edit a file that is > 4GB. I just need to put content at the end and beginning of the file. I suppose I could use something like

To append to the file. Is that the route to go? What about prepending? In general, what is the best route if I wanted to edit somewhere in the middle?
I've tried VIM and it fails miserably. I assume emacs and nano would be even worse. What else is there? I assume to accomplish what I am looking for, the editor would have to be specifically designed for this by not keeping the entirety of the file's contents in memory.

I am thinking of appending something to each line in a text file with Java. I prefer not write a new file with content appended from the old one.That 'something' would probably be Time Stamp when the file is created (which is same for each line).I am not sure Java provide some easy way for it or not
