Convert and resize images using imagemagick

This past memorial day weekend I took a bunch of pictures which I wanted to post to the web. Web photos are best viewed in 800x600px and I had a lot of them. So I used a simple command to do it.
Code:
for x in `ls -1`;do convert -resize 800x600 $x `echo $x | sed 's/.JPG/.png/'`;done
mkdir web_album
for x in `ls -1 *.png`;do convert $x web_album/`echo $x | sed 's/.png/.jpg/'`;done
rm *.png
Now I don't have to spend all my time in Gimp with that simple batch command.

DVD Ripping

Posted 04-25-2011 at 10:54 AM by sag47

I work for a Scientific Institution and a company which recorded talks decided to give us all the talks in DVD format instead of a hard drive full of video files. This is kind of counter intuitive however luckily I use Linux at work. Long story short mencoder with lame installed solved my problems.

Code:
mencoder 
-vf harddup 
-vf-add smartblur=.6:-.5:0,unsharp=l5x5:.8:c5x5:.4 
-xvidencopts fixed_quant=4:profile=dxnhtntsc 
-lameopts cbr:br=128:aq=0:vol=1

Recently (within the past year) I have helped a user with a problem converting hundreds of images into individual PDF files. I was pleasantly surprised to find imagemagick to effortlessly do this.

Command line tool imagemagick does what you need if they're images.
Installation:
Code:
sudo apt-get install imagemagick
Usage: (coverts all images into one pdf)
Code:
convert *.jpg foo.pdf
Usage: (converts each image into an individual pdf)
