When using "read -t" in bash script predefined variable becomes empty. Example:
VAR="jonas"
read -t 3 VAR
echo ${VAR}
When user does not input anything and timeout is passed (3 secs)
variable VAR becomes empty. When doing the same in Mac OSX with:
$ bash --version
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin12)
Copyright (C) 2007 Free Software Foundation, Inc.
it works as expected as:
$ VAR="jonas"
$ read -t 3 VAR
$ echo ${VAR}
jonas
