I need to have regular user run this command sync; echo 3 > /proc/sys/vm/drop_caches
but it requires root privileges that I cannot give.
So I figured they could run the command as "sudo". I looked in /etc/sudoers and wasn't sure what I needed to edit for the users to run the following command
sync; echo 3 > /proc/sys/vm/drop_caches
edit the sudo config file to allow my account to use some commands as a root.so can someone advise me how should i do it.

View 2 Replies View RelatedI am here with a troublesome question about my new Ubuntu set up. Well as I've found out that you have to use the Sudo command to edit anything out side the home directory. Well I am using L.A.M.P. Server on my computer so I can host a small forums. Well for example like lets say I install Word press Blog onto my lamp server and I want to install a theme well when i go to install a theme i can not because WPB can't install the theme because of the security stuff on Ubuntu!
Well I want to know if there is some kind of command or program i can use that will get rid of all the security stuff were i can edit stuff nice and easy. Like something that can give me FULL control over the OS so no more commands because I am going to be running a Vbulliten forums which needs themes and plug ins, well i want be able to install them because this OS will not let me!
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?
My OS is Linux Fedora 11.PC is IBM 1.8 GiB memory, Intel Duo E8500@3.1GHz.The modem I want to install is a USB stick from 'Cell C' the service provider.The code I got from the internet is for Ubuntu. I am new to Linux. When I type the code in at the Terminal, it tells me that Fdeb (my user login name) is not in the sudo file. How do i get my name in the sudo file?

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?

it doesn't work, if i put the command in a .desktop file.
Debugging some of my scripts after upgrading from Debian Lenny to Ubuntu 10.04. In so doing, I tripped over this "problem," the solution to which may give me a clue to others.
On a bash shell command line I created a file thusly:
sudo touch zero_file
and it lists as expected with default permissions 0644:
-rw-r--r-- 1 root root 0 2011-03-09 11:18 zero_file
But then this command fails
sudo echo abcdef >>zero_file
-bash: zero_file: Permission denied
I can place the command (minus the "sudo") in a script & run it under the auspices of sudo & it works. Am I missing something re the stdin redirection when using sudo?
If I try the sudo mv command on the file listed below I get the error listed. I am confused. It is my file & I have permissions. Somehow a slew of files on my system are now showing this way. This seems to correspond when I ran rsync from my netbook to sync it up with my desktop where I am having a problem.

I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?
EDIT: /etc/sudoers looks like:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
##Me
user1 ALL=(ALL) ALL

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.
Recently I migrated from Ubuntu to Debian, first thing i wanted to do was to give myself sudo permissions and lock the roir account. By default sudo group don't have permissions to do this on debian, so i wanted to edit sudoers file by typing visudo. But i keep getting this

I have made a simple bash script through which i can add, del, edit user from certain file using different CASE variables. like
case
1. adduser
2. del user
3. edit user
Now i want to add a exit CASE like
1. adduser
2. del user
3. edit user
4. exit
Now i want to make a script such a way that, if user input is 4 then only script quit. I used with exit function also but it didn't work. if user press ENTER or other keys then also it quit the program.
