Things I've found useful

Reading a text file into bash with a for loop can produce unexpected results if a line in the text file has spaces in it.

If you had a text file with this line in it:

d/NON STUDIO/NON STUDIO105/Cavanaugh_M0228867.jpg

And you were to read it with this simple script:

for i in `cat image.list `;
do
echo $i
done

You would get the following output which is probably not what you wanted:

STUDIO105/Cavanaugh_M0228867.jpg
d/NON

If you use while instead of for and unstset the IFS like this:

while IFS= read line
do
: do whatever with $line
done < FILENAME

You will get the desired output of:

d/NON STUDIO105/Cavanaugh_M0228867.jpg
