I need to edit a line in a file in gedit, but its read only. I need to change
; default-sample-rate = 44100
to
default-sample-rate=44800.
Would anyone know if there is an option to make a read only file editable? Judging by the responses to the thread I followed to enable my soundcard, it is possible, and perhaps there is some setting etc that needs changing
My sample rates are out of whack and I need to edit the daemon.conf file.
However if I use
Code:
It will open the file but will not let me edit at all. If I just navigate to it I can edit it, but I can not save it!
I tried going in as root from the terminal and using the code above and I get a weird error.
Something like:
Then it says core dump.
Am I missing something to be able to edit the daemon.conf ?
I don't want ubuntu to clean /var/cache/apt/archives directory automatically... is it possible to make it permanent by editing any conf file?

I have two txt files containing x and y coordinates: xcoord.txt & ycoord.txt. I need to open them; read them line by line to get each coordinate; then each time I need to update Xs and Ys parameters inside another file called "dc.in" with the grabbed values.
Finally each time I need to run two exe files ( dc_2002 and st_vac) and produce corresponding output for each Xs and Ys ( dc.in is an input file for this exe files)
I have written the following code but it does not work:
bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file. So, all the code must be inside a loop, and inside the loop, the first thing should be to read the next line from the file. I have the bash read command. But it reads from stdin. Any way to make read from a file?

so I have a script that creates couple of txt files. First file output is something like below..
cn=test,ou=something,ou=some,o=org
cn=testa,ou=something,ou=some,o=org
cn=testb,ou=something,ou=some,o=org
second file output is something like below..
usera
userb
userc

for i $(cat user.txt);do
echo "$userdn"
done
done
when I ran both ldapsearch commands invidually, they work fine. But when I ran script, I got first file correctly but not the second one. It looks like its not reading the first file correctly and not setting the variable ($userdn) value correctly in the second ldapseach command. I want read first file first line and run the second ldapsearch and continues, then read the second line..and so on.
im trying change my etc/sysctl.conf file but it won't let me as its read only. how to i change this?
View 2 Replies View RelatedI am trying to edit my grub.conf file. I am logged in as root. It says it is a read only file. I have tried to set permission with chmod 777 and also tried through GUI. Using VI it says it's a read only file. Using nano it will not write either. I have two choices on boot up. I want to automatically go to second automatically. First at the moment is CentOS-4 i386 (2.6.9-55.ELsmp) and second is CentOS-4 i386 (2.6.9-55.EL).

View 6 Replies View Relatedhave been playing around with a script for a few hours and now I need to be able to output the lines in a text file one by one to be used later in the script.What it gonna do is to read a log file and grep the usernames, then write them to a file, and then run one script for each user, to search for more information about them in the log.But I don't know how to output a single line from a file, and google does not return any solution.

read a files's specific line but return as argument only part of it ie

value # this is mass
value2 # this is force
so, how can I get / use the $value and $value2 as arguments for some other file and skip the rest of the line(s) ? of course, the values are different everytime, but the comment always the same, as well as the position of the lines in the file
i am trying to read in a file 1 line at a time and for some reason it stops printing out at about line 62,000.
i am doing this:
Code:
while(fgets(c0, 1085, fstream0) != NULL)
but after about 62,0000 lines it stops printing. no seg-fault, no core dump. it just stops printing to the terminal then returns me to the command line after a couple of minutes. as a hack i am doing split -l 50000 on the input and calling my program 5 times.is there some limitation on fgets that i am not understanding ?
I'm writing a program which now accepts user input:
Code:
echo "Enter a date in the format YYYY MM DD hh mm ss."
read gregyr gregmo gregdy greghr gregmn gregsc This lets the user input a date and time, such as 2011 06 21 15 12 45, and have each number assigned to their corresponding variable. Later in the program, these variables are put into an equation, and then the terminal spits out the answer. Now I have to have the program read all of the lines from a text file, which is in this format, assign the variables.
I have installed RHEL5, solved the problems around it and started to set up the GRUB. I have set the menu.lst with simple
rootnoverify (hd1,0)
mkeactive
chainloader +1
and tried to boot the Win7 on that partition. NO LOADER came up and since that moment
Grub is only in "Minimal BASH-like line editing" mode. I have tried all of I have googled, nothing have worked. There is a problem with even finding /boot/grub/stage2, or anything else, grub won't let me mount any partition. When I try to find any file, it says file not found. It is important to say that all I did to cause this was change in menu.lst
rootnoverify (hd1,1) to rootnoverify (hd1,0)m nothing else! There is no logic in this....
I'm running the ubuntu based Green OS and cant get my video card properly configured. i've already gone through the forums to figure out what i need to do to get my ATI card working but my system wont let me access the xorg.conf file. i can see it using the the GOS file editor but it wont let me save the modifications. when i attempt to edit from a terminal window with su privelages it tells me that /etc/x11/xorg.conf does not exist. i've even tried booting into recovery mode and using the root instead of the sudo command. nothing i've tried will let me open the file.
View 3 Replies View RelatedI ran into it while google Segmentation Fault. I'm writing a simple C program that reads a file that counts each line and numbers it then writes to a file called sdout. I copyed my program mostly from the text book but im still having problems. Heres my code:

instead of importing a file I would like to use the variable $x I tried using pipes, but with no luck. My goal is to read one line at a time, but not have to export my data to another file, I would like to keep it all within one script.
My laptop screen isn't working but I don't want to abandon my laptop so I am trying to hook up a new monitor. I'm using my 1 HDMI port, and my BIOS doesn't recognize the monitor on boot up. Also, my xorg.conf file is not configured for this monitor. My question is what should my xorg.conf look like? I have a bit of a start on it(see attached) but it is not quite right. How do I set up the Toshiba as the default screen, in order to use this monitor when Linux starts? Other info: I use Debian 5.0 with Gnome.
View 4 Replies View Relatedcups does not start with the server. When I try to start from the terminal I get the error message

The log files show nothing. cupsd.conf exists. It is user - root and group - root with permissions set at 0644.
My interpretation of this is that the program is not launching from either boot or terminal for a fundamental reason. I do not quite see what that reason is .
