What I want to do is to find keyword in config file and change its value - that must be done using script.
I could write script usig awk and etc - but maybe there are already prepared ways/commands to change standard configure file setting?
I have recently installed Ubuntu Karmic on my laptop, which also has Windows 7. It now has GRUB, and I have been able to modify some settings via the GRUB command line. However, these changes are not permanent; they are reset the next time I load GRUB. I have seen many people trying to configure GRUB who have been pointed towards /boot/grub/menu.lst. I expect it would) I went to edit that file... and discovered that it did not exist. I am certain that I am using GRUB, not some other bootloader. Is there another possible way to configure GRUB, or somewhere else I might look for this file?

View 7 Replies View RelatedIs there some sort of standards file path convention for installing softwares that I could follow through? For example, I just learnt how to build Nginx from source. But the default binary path set by nginx is "/usr/local/nginx/sbin". I have seen a couple of tutorials which they specify the location of the installed binary and it is very different from those usual default paths. Thus, got me thinking whether is there some form of file path convention that I should follow?Is there some kind of list which states where do those packages on Debian.org Repository usually installed to?
View 6 Replies View RelatedI have on my windows machine several hundred files that are a format of .nc .ncs for a CNC machine. I need to convert them to txt which is something as easy as opening in notepad and then saving as .txt but there are so many that this kind of action would take way too long.
The reason I am writing the linuxquestions is because I would feel more comfortable in loading a live CD and using some sort of terminal command to do this than I would to download one of the many "freeware" type programs I have found for windows (even more so since I have had a root kit before and had to start all the way over to get rid of it).
I need to know:
1. Is this possible to do with the terminal without super advanced knowledge.
2. Can one please point me in the right direction; something to read or an example
Is there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".

I need to change one word in over a thousand pages of HTML. I think sed is the only way to do this, but I've never used sed before.
After reading the documentation, I see that it is pretty easy to alter files to standard output, in other words, the screen.
But I don't want to do just alter text to the screen, I want to alter the original file, else I am not doing any Stream EDiting as near as I can tell.
None of the documentation explains how to take a file, apply sed to alter that file. How do you do this?
Code:
[myuser@myhost dir]#sed s/changethis/tothis/ /mydir/myfile
How do I apply sed to actually make the changes to myfile?
I need to have regular user run this command sync; echo 3 > /proc/sys/vm/drop_caches

View 1 Replies View RelatedI 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 trying to have the files from /user/directory copy every hour to /backup/user/directory. It would seem that cron or crontab is what I need to use. Looking at previous posts and other documentation only shows how much I don't know. When I type crontab -e I get a blank file I can type into, seemingly using vi as the editor. I have no problem with that but when I type cron -l, I get my text after a message about "Do Not Edit this File". What I am reading just makes no sense, I am not understanding even the most fundamental aspects of cron or crontab. Where I can get the most basic of basic instructions to try to understand this function?

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
cat "text to add" >> huge_file
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 have created virtual cd (using damoen tools) for opensuse 11.2 installation from standard iso file and that installed installer for opensuse in my C drive and asked me to restart. After I restarted it gave me two options during boot, vista and opensuse 11.2 installer. I tried installing opensuse 11.2 from boot option and it asked me for language>country>installation. From the installation window which gave three options, I selected installation option and after preparing system for installation it asked me about sda location....I had separate partition which I selected and after that it is asking me for source which I don�t know what it is. I tried few things but no success and then tried to get in to vista but unfortunately it is not booting in vista as well and takes me though the same process explained above.
So both my boot options are trying to install opensuse 11.2 and stops at provide source window. So in a nutshell I am stuck and not able to use my system. For your information I don�t have vista installation cd so I can�t repair vista.
Is it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
I have a weird problem with one of my servers. When system is booted and right before I should se "INIT 2.86 starting..." message, all the messages disappear. Only kernel messages get logged to console and later login prompt, but nothing in betweek (there are 20+ services starting successfully, just without emitting a single character).I checked /proc/PID/fd of the boot script (in my case called /etc/rc.d/rc.boot but that does not matter).
The only significant difference in hardware to other servers is that this one runs RV350 AP [Radeon 9600] graphic card.Now, my question is: where could those FDs go or why are they not opened?Does anyone have a clue about this, or a hint?
