谢谢回复!确如你所说,是跟这些变量有关.
________________________________________________________________________________
MAIL If this parameter is set to a file name and the
MAILPATH variable is not set, bash informs the user of
the arrival of mail in the specified file.
MAILCHECK
Specifies how often (in seconds) bash checks for mail.
The default is 60 seconds. When it is time to check
for mail, the shell does so before displaying the
primary prompt. If this variable is unset, or set to a
value that is not a number greater than or equal to
zero, the shell disables mail checking.
MAILPATH
A colon-separated list of file names to be checked for
mail. The message to be printed when mail arrives in a
particular file may be specified by separating the file
name from the message with a `?'. When used in the
text of the message, $_ expands to the name of the
current mailfile. Example:
MAILPATH='/var/mail/bfox?"You have
mail":~/shell-mail?"$_ has mail!"'
Bash supplies a default value for this variable, but
the location of the user mail files that it uses is
system dependent (e.g., /var/mail/$USER).
