The -e flag causes read to use GNU Readline if the input comes from a terminal. This is *very* useful, since Readline allows you to perform text manipulation functions, completion, advanced cursor movement, etc. Also, the likelyhood of this being a real security issue is very small. -- Eduardo Bustamante https://dualbus.me/
