loop over a set of items that contain spaces
If you want to operate on a set of items in Bash, and at least one of them contains spaces, the `for` loop isn't going to work the way you might expect. For example, if the current dir has two files, named "file" and "file 2", this would loop 3 times (once each for "file", "file", and "2"): $ for ITEM in `ls`; do echo "$ITEM"; done Instead, use a while loop with `read`: $ ls | while read ITEM; do echo "$ITEM"; done
