I have a set of bash scripts which I need to execute through a web-interface. So that they can be executed remotely, once the web-interface is hosted on a server. Since this is the first time I am trying something like this, I am not sure what language or technology to use for such work. From my knowledge PHP could be a good fit. But not really sure.

View 1 Replies View RelatedI'm trying to do a shell script which are suppose to run a program as a specific user at system boot up. The problem is that I don't know for sure how to make the script add the users password to the prompt when it's necessary.
Basically the program would be run like this:
sudo -u extrema program_name -r /srv/program_name -d
and in this example the password is, "hidden".
How would I make this script run this program as user extrema with the password "hidden" at boot-up? I know how to put the script in the rc.X directory and so on, its more the syntax of the code.
what program runs the Session lock and the screen saver for gnome and KDE on centos 5.5. But most importantly id like to know what the config file for the screensaver/session lock is called and where its most likely located.

I found a great solution in my case for MacOS users called SelfControl, but as you can guess ... there's no Linux native client for that. So, my question is - is there any easy and understandable way to block specific webpages for a predefined time period (let's say, every morning from 03:00CET - 08:00CET)?
OS: Ubuntu 9.10 Computer knowledge of the farmer: Getting on Farmville and/or playing Gnome's Mahjongg is pretty much all.

I have for example the following IP addresses:

41.239.36.19
63.215.202.234

How can I sort those IP addresses? I want to sort them using the first 3 numbers I also want to count the number of times that address is repeated This is a batch program.
I wrote this script which works but it should run automatically about once per week. I hunted and experimented with KDE Task Scheduler (no dice and no help anywhere) and cron (confusing instructions and cannot edit crontab -e with vim, and cannot enter cron folders/files). I would settle for a desktop shortcut to run the script but found no for that.
Script:
Code:
#!/bin/bash
xterm -hold -e fstrim -v /

I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh

write jcummins
this message should go to jerry
echo "the message didn't send and this string will not appear"
echo "it appears it has stopped at the write command"
I am trying to write a bash script that installs a program fully automated for me. I am stuck at the one part where i need to change a line in one config file. I have tried various syntax for sed and none have worked. Maybe someone can suggest how to go about this. Since the line appears in the middle of the file, I can't use echo or cat. Also the file will be diffrent lengths depending on the install.
The line I need changed is:

the last syntax i tried is:

I have a machine currently running Debian Lenny on which I would like to run Ubuntu for the driver support in its newer kernel. However, I did a test boot from the installation CD and it appears to be running at less than half its rated speed. This is the output from the Debian kernel:

Linux kant 2.6.26-2-amd64 #1 SMP Wed May 12 18:03:14 UTC 2010 x86_64 GNU/Linux

Maybe this is some sort of power save bug where the CPU speed is incorrectly scaled back. Has anyone else encountered this problem? Should I report it as a bug, and, if so, how do I do that?
When I start rythmnbox, Xorg goes up to 96-98% of CPU and stays there. It goes back down to below 10 when rbox is minimized or closed.
