bash loop

• This example will loop through all files and folders, and determine their disk usage (note that this particular example can actually be done without a bash loop, using only the du command)

• This code WILL work on filenames with spaces
• taken from http://www.macgeekery.com/tips/cli/handling_filenames_with_spaces_in_bash
• quote “For splits items on a space, regardless of if they’re quoted (if they’re stored in a variable). However, the read command does not.”

ls -1L *.tiff | while read file;do
du -h -d 0 "${file}"
done

• This code will NOT work on filenames with spaces
• note that the symbols used are backticks, not single quotes (backtick is the key left of 1)

for file in `ls -1L`;do
du -h -d 0 $file
done
