Bash Problem Solving - Excercise No. 1

Create a command to search your home directory for jpegs, gifs, pngs, tiffs (and any other graphic file format you can think of) and list any files newer that two days old and larger than 2 megs, and also owned by the current user.

Thanks again to David Jackson. Feel free to contribute.

I used the 'find' command to accomplish this:

find . -name \*.jpg -user $USER -mmin -2880 -size +2000k -o -name \*.gif -user $USER -mmin -2880 -size +2000k -o -name \*.png -user $USER -mmin -2880 -size +2000k -o -name \*.tif -user $USER -mmin -2880 -size +2000k

I'm thinking there must be a shorter version -- what with all the repeated mmin, user, and size options. The only other way I could think of was to write it into a shell script with a 'while'. Other ideas?

Hi Megan.

Find seems to definitely be the right command here. I think you could save a good number of keystrokes with brackets, like so:

find ~/. -name "*.{jpg,gif,png,tif}" -size +2048 -user $USER -ctime -mtime 2

This is David Jackson's answer and it seems like the best way to me.

Here is ExcerciseNumberTwo.
