A batch file version of the same command would be:
for f in *.m4a; do ffmpeg -i "$f" -acodec libmp3lame -ab 256k "${f%.m4a}.mp3"; done

Yes, You could do it in the GIMP or even use Inkscape to auto-align the clones, but the command line is so much easier.
NOTE: The +clone and -clone options are just to shorten the command line instead of typing the same filename eight times. It might also speed up the montage by only processing the image once, but I'm not sure. "+clone" duplicates the previous image, the following two "-clone"s duplicate the first two and then the first four images.
NOTE2: The -frame option is just so that I have some lines to cut along.
BUG: I haven't bothered to calculate the exact geometry (width and height) of each image since that was not critical for the visa photos I need. If it matters for you, it should be easy enough to set using the -geometry flag near the end of the command. For example, if you have your DPI set to 600, you could use "-geometry 800x1200!" to make each subimage 1⅓ x 2 inches. You may want to use ImageMagick's "-density 600" option to put a flag in the JPEG file cuing the printer that it is a 600 DPI image.
BUG2: ImageMagick does not autorotate images based on the EXIF information. Since the portrait photo was taken with the camera sideways, I made the JPEG rotate using jhead like so: jhead -autorot 2007-08-25-3685.jpg
You can use multiple field separators by separating them with | (=or).
This may be helpful when you want to split a string by two separators for example.
#echo "one=two three" | awk -F "=| " {'print $1, $3'}
one three

I have a remote php file that I want to run once an hour. I set up cron to run this wget. I don't really care about what's in the file though, I don't want to save the results, so I run the -O and send it to /dev/null
Sometimes you have a situation where you cannot properly see the ls output when you are using a terminal w/a dark background. Usually bash has ls aliased to use colors, and you can easily get ls to use the default foreground color via simply unaliasing the command.
