Tip Of The Day (2) : Batch resizing pictures in linux

How to batch resize pictures in Linux (Mint and Ubuntu based distros)


Don't forget to read the other tips:
  • Tip Of The Day (5) : Batch Script to resize pictures in linux (Nemo)

  • Tip Of The Day (4) : Bulk renaming files in linux
  • Tip Of The Day (3) : Linux Mint 13 and Petra Backports
  • Tip Of The Day (1) : Screenshot 



  • first install imagemagick
    sudo apt-get install imagemagick

    then open in terminal the folder containing your pictures you want to resize, and then type the following : 
    for file in *.[picture extension]; do convert $file -resize [size you want] [new-name]-$file; done

    example, for .JPG files that you want to resize in 800*600 (the file will be sized to fit in a 800*600 frame without destroying ratio)
    for file in *.JPG; do convert $file -resize 800x600 resized-$file; done

    Your resized pictures are now called resized-*.JPG (original pics are not overwritten) ie : 
    DSCF2248.JPG is now called resized-DSCF2248.JPG

    Now you have forum-ready pics, for fast upload and quick sharing ;)


    That's all folks !

    CCFL : some experiments

    A while ago i took apart some screens with CCFL backlight, and then did nothing with it.

    It's time to change that ! 



    What is used : 

    • Old PSU
    • CCFL inverter bought in a electronic shop
    • Some CCFL took from screens
    • some electric wire
    • soldering iron
    • soldering tin

    the CCFL tube is longer than the Inverter can handle, that's why i played with it,with a smaller one i got a geeky desk light.

    here is the lighting circuit : 



    here is the result : 


    And in the dark now : 



    Ok, This was pointless ... but that was fun to play with
