# How to determine if a bash variable is empty?


# A variable in bash (and any POSIX-compatible shell) can be in one of three states:
#
# unset
# set to the empty string
# set to a non-empty string
# Most of the time you only need to know if a variable is set to a non-empty string, but occasionally it's important to distinguish between unset and set # to the empty string.
