Hi guys. I will be frequently needing to convert .jpg files to 183x183 .png thumbnails. I can't quite seem to wrap my head around how to make a for loop to do this.

With the help of my friend (who may have mislead me, I'm quite confused) I've got this.

This is bash

the command is: pngify <source directory> <destination directoy>
Code:
for picture in $(?) ====> I'm quite sure this part is wrong...
do
        echo ${picture%.*}>picturewithoutext     =====|This part is to remove the
        picnoext=`cat picturewithoutext`        ======|extension so I can name
        rm picturewithoutext                   =======|the new file the same thing with a .png

        convert -size 183x183 $1/$picture $2/$picnoext.png  
done
Yes, I am very new to shell scripting ^_^;;
