That is *extremely* odd. The only way that could happen is if you've turned on the "-i" attribute for the MAILCHECK variable. This is not the default. hobbit:~$ bash hobbit:~$ declare -p MAILCHECK bash: declare: MAILCHECK: not found hobbit:~$ MAILCHECK="" hobbit:~$ declare -p MAILCHECK declare -- MAILCHECK="" hobbit:~$ declare -i MAILCHECK hobbit:~$ MAILCHECK="" hobbit:~$ declare -p MAILCHECK declare -i MAILCHECK="0" If this is something you've done, I advise you to undo it.
