### Exceptions ### Exceptions
If you want to read word by word, you should still use a while read loop (e.g. with `read -a` to read words into an array). If you do want to read word by word, you can set `$IFS` appropriately and disable globbing with `set -f`, and then [[ignore]] this warning. Alternatively, you can pipe through `tr ' ' '\n'` to turn words into lines, and then use `while read`. In Bash/Ksh, you can also use a `while read -a` loop to get an array of words per line.
Rare reasons for ignoring this message is if you don't care because your file only contains numbers and you're not interested in good practices, or if you've set `$IFS` appropriately and also disabled globbing.
