I am running a shell script from a rc file in Linux. The shell script is going into a loop which runs for 8 hours. Now I want to prevent the shell script from running when Linux boots or I need to find a way to kill the shell script when it is running. I tried using killall, kill $! and Ctrl+C etc. Nothing seems to work. Can you suggest a way out. I am new to Linux.

Is there an easy way to prevent the logging of commands run into syslog as post-shell expansion?
I.e log a command of "ls *.log" as just that, rather than "ls a.log b.log c.log d.log" It makes rather a mess of the log files.
I apologize if this is the wrong place to ask, or if this has been asked before, but it has been bugging me for some time and I have not had any luck with it. I imagine that my problem is not unique to my circumstances, but here goes.I am running Arch Linux, and quite frequently watch videos, particularly flash, in fullscreen. However, eventually, the screensaver appears, and starts dimming the screen. I have the screensaver set to run whenever the computer is 'idle'. Does anyone know a way to either.Stop the screensaver from appearing when in a flash video or watching other video?Stop the screensaver from appearing when a flash video or normal video is full-screened? Heck, even..Let the screensaver know that my machine is not idle when watching flash.

On my crontab there is an entry to run a script I wrote that backs up my local files to my remote server. It was working great, running once a day. However, I now want to make the script run every hour.The problem is that if there are too manyfiles to transfer (Example:I ripped a DVD in the last hour) the actual backup may take longer than 60 minutes.So I want to modify the script to check if my backup script, based on rsync, is running. If rsync is still running then do nothing and exit the script. If it is not running, execute the script as normal.

For example, when I click on pause in vlc, the terminal should show me what command it used to pause vlc. What's the closest ting I can get to this?
View 1 Replies View RelatedI added the following line in /etc/sudoers file
<username> ALL=(ALL) NOPASSWD:ALL
after adding this if I run any command it is not asking for the password. Now I need to shutdown the remote machine with sudoers user.
I've found myself using the -v flag for lots of applications less and less (especially for trivial stuff like tar and cp). However, when I did and I was, say, unzipping a large file, it would take longer than when I didn't use the -v flag.I assume this is because the terminal has to process the text and I'm filling up whatever buffer it might have. But my question is, does this make the application actually run slower or does it complete in the same amount of time and what I'm seeing is the terminal trying to catch up?

View 1 Replies View RelatedIn a script I am writing I am trying to add logic so that the script can figure out if a remote server uses rpm or dpkg and then run the appropriate command to print a list of installed packages. This works locally, but I need to get it to work through SSH and I have no idea how to do that. The relevant portion of the script is below. It would also be nice to find a way to not need the full path to the executables but I'm not real concerned about that.So anyone know how to make this code work via SSH?
Code:
if [ -x /usr/bin/dpkg ]; then
dpkg --get-selections
[code]...
My current script is as followed:
Code:
#!/bin/sh
su et
cd "media/ET"
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
[code]....
I want ET to be run as the user "et" and for some reason, I can't directly su/sudo to run the file without being in the user "et" and the "/media/ET" directory.

I want to prevent users changing the wallpaper, as i couldn't found any direct method I thought of preventing the /usr/bin/gnome-appearance-properties being running,
I know that the user also can set the wallpaper without running that . But didn't found any other way .
I tried to use SELinux to it and I'm stuck at writing a own policy.
According to SELinux, it prevents everything ., but as i have mapped the user to a SElinux user ,even though he can use administrative tasks , he can run the appearance window. that means he has got the permission from a different policy , Currently I'm stuck at this place.
Suitable way to prevent the wallpaper being changed by the normal users.

I have been trying to figure out how to automatically run terminal commands on login. For example, I want to run Firefox on login. When I run 'firefox' in terminal, it opens. This is what I tried:I went to System > Preference > Startup Applications and clicked on 'Add'. I gave it a name, typed 'firefox' into the command field and left the comment blank and added it to the list, making sure that the box was checked.
View 1 Replies View RelatedI am trying to run some simulations through SSH from my mac on our university SOLARIS system. My problem is that whenever I want to execute a command I get an error which says "Invalid argument". Maybe I should explain more what I want to do and what I did.Firstly I installed a software which I need to run, I did it through ThinLink, and it seems that it is running fine without a problems. I can execute all commands and scripts. Installed software contains tens of small programs. I have compiled it and assign the PATH to be able to use the software. This was still via ThinLink. Then I wanted to start to use SSH since it should be more secure and also faster for me. When I wanted to do same think as in ThinLink I got the message Invalid argument. For example I run a command which use program gensky. I wrote:
Code: gray1(dava) $ gensky 4 4 4
I got:
Code: -bash: ............/Radiance_install/bin/gensky: Invalid argument (i replaced the path to my home directory by dots) The PATH to the program seams correct but it does not run correctly. With SSH I can log into the remote machine and see all the files which I have on the disk as well as to run standard commands like mkdir etc. But I cannot run the programs which I installed.
what i want to do is run two commands (nautilus and gedit) from the command line/shell script at the same time. i can obviously do && between them, but this requires the first app to close before moving on to the second one. i want to run both apps at the same time so i can run gedit with some project files open on it, and nautilus to browse those files/other files.
View 10 Replies View RelatedI have set up ssh to connect with a RSA key to a router. Now, I want to be able to run a chain of commands on that router the problem is that I can't send them separated with ; cause the router doesn't understand the separation, so I have to send the "<enter>" keys somehow. I tried to do it like this:
( echo ping localhost; echo ping localhost; ) | ssh -i blah user@router
The connection is established, but it gets broken after login and no command is executed. Is there a way I could tell ssh to read a text file where the chain of commands is?
I use two separate systems both running Debian 8. On one (my main) I can't do some commands including ping, shutdown and reboot without running them as root user, however on my other system I can ping and reboot as a non-privileged user. The permissions on both systems are the same for /bin/ping and /sbin/systemctl (reboot). I thought at first it was something to do with what groups my main was in, but that doesn't seem to be the gase.
I know I can fix it by setting setuid for both, but my question is why is it different on both machines? Is there a global setting controlling this in /etc or perhaps an icmp setting?
Having recovered from busting my installation, feel urgent need to know what I did to set it up.So...would like to see all commands I ran in terminal window and store them (execute as script in future?)I can see prior commands using up arrow, is there a way of storing all of those commands in history?Also, any pointers to setting up sort of backup of the package installation setup?
View 7 Replies View RelatedI recently hired a new tech guy to start managing our servers. In doing this I went ahead and upgraded all the servers. It has been awhile now since I sent him the details of the new server and the last time I talked to him he was joking around with one of the other clients not realizing how long it took.
I know on other server moves, my old guy could have everything setup and running in a couple days as a good amount of time is waiting for the data to copy over. I am starting to wonder if this guy is going to try and throw a huge bill at me, so I would like to know what hes doing on the server with time stamps just so I can get a idea of how much time he has been logged into the server. Does this server OS have anything like this built in?
