Bash – [: =: unary operator expected

[: =: unary operator expected |
Use:
|
1 2 |
if [ "$aug1" = "and" ]; if [ "$aug1" = "and" ]; |
because otherwise, if $aug1 is undefined or empty, it vanishes from the scene of the crime, leaving only
if [ = "and" ];
which is not valid.
With the modern [[, you don’t need to worry about that. It has lots of other nice features, too.
