    I made some scripts for everyone's convenience!

    I made a couple of simple installation scripts to install some programs, one is to install either Oracle Java or Open JDK, and the other is to install Skype 4.0, which a lot of people like!

    The Java Installer Script is here
    And the Skype Installation Script is here
    Keep in mind that you will need to give the scripts executive permission by doing
    Code:
    chmod +x whateveryounameit
    Enjoy! Let me know if it doesn't work on an OS based off of Ubuntu (Linux Mint, Xubuntu, etc.)

    Please post what 'based off' distros they work with, just to help certain people here know, and list any issues implying there are any.

    Re: I made some scripts for everyone's convenience!

    Here's a script I just put together to automatically change the wallpaper in Gnome Shell. I think it will also work in Ubuntu if Unity uses gsettings for the wallpaper (which I think it does?). Someone's probably done this before, but here it is. You run it as:

    Code:
    ./wallpaper_switcher.sh $time
    where $time is the amount of time to wait in minutes before switching the wallpaper. In the script, you will also need to change $dir to the directory with the pictures you want to use as a wallpaper. You can set up this script to run on startup, of course. The script will select a picture at random every $time minutes from the available files in the directory you specified.

    I figured this thread was as good as any to post this, but let me know if there's a better place.

    Code:
    #!/bin/bash
    
    # Wait time specified in minutes
    time=$1
    
    
    dir=/home/dprosser/Pictures
    
    
    # Get list of pictures and number of pictures
    npic=1
    while read line; do
      pic[$npic]="$line"
      npic=`expr $npic + 1`
    done < <(ls $dir)
    npic=`expr $npic - 1`
    
    
    # Change picture every however often is requested
    I=1
    while [ $I -lt 2 ]; do
    
    
    # Select a random picture from the list
    number=$[ ( $RANDOM % $npic ) + 1 ]
    
    
    # Change the wallpaper
    gsettings set org.gnome.desktop.background picture-uri file://${dir}/${pic[$number]}
    
    
    # Wait awhile
    sleep ${1}m
    
    
    done

    There's probably a more automated way of doing this, but this works for me!

    time=$1 
    
    # Directory containing pictures
    dir=/home/dan/Wallpaper_slideshow 
    
    # Number of pictures
    npic=16 
    
    # Picture names
    pic[1]=DSCN0844.JPG

    # Change picture every however often is requested

    while [ $I -lt 2 ]; do 
    
    # Select a random picture from the list 
    number=$[ ( $RANDOM % $npic ) + 1 ] 
    
    # Change the wallpaper 
    gsettings set org.gnome.desktop.background picture-uri  file://${dir}/${pic[$number]} 
    
    # Wait awhile 
    sleep ${1}m 
    
    done
    It's fine, people can post their scripts here, I don't mind.

    Re: I made some scripts for everyone's convenience!

    Just a heads-up, I improved my script above so that it automatically reads in the list of pictures in the directory you specify. So now all you have to do is specify the correct directory in the script and it will automatically populate the list and figure out the number of pictures for you.

    As a word of caution, if you do have other files in the directory that are not pictures, it will include those in the list as well.

    Re: I made some scripts for everyone's convenience!

    Here's another one. Every time I want to watch a video, I find myself going into the power settings and changing it so the screen stays on and it doesn't suspend automatically. Then I change it back when I'm done watching.

    I decided this is inconvenient, so I made a script to do it. Run it as:

    Code:
    power_toggle.sh $CLO
    where $CLO may be -off, -on, or none specified. -off will turn these power saving settings off so you can watch movies, etc, and -on will turn them back on when you are done. If no CLO is specified, it will toggle the power settings; e.g. it will go from off to on or vice-versa.

    Here is the script. The settings for -on mode are specified in seconds and may, of course, be modified.

    Note that this only works for DEs that use gsettings, which means not KDE.

    Code:
    #!/bin/bash
    
    # This script automatically changes power settings, so that the screen will
    # not turn off and the computer will not suspend e.g. when user wants to watch
    # video.  
    
    
    # Input argument: 'off' or 'on'.  If no input argument is specified, then
    # will toggle power saving mode - the opposite of the current setting.

    Thanks! I think I will be using this a lot, so I put it in /usr/bin so I can run it with ALT+F2.

    Re: I made some scripts for everyone's convenience!

    If anyone is using that script, just FYI it's been updated. I couldn't get it to work reliably at first. It turns out there is a setting in org.gnome.desktop.session which needs to be changed in addition to the ones in org.gnome.settings-daemon.plugins.power in order to keep the screen from dimming (at least on Gnome 3.8 - it's possible this might be desktop dependent). Now it works well for me. I just run it once to disable the screen turning off, suspending, etc., and again to turn those things back on.

    If anyone else is using the script, could you let me know if it's working correctly for you?
