请问这个shell script的最后一句有没错
#!/bin/sh
# Filename : whatever_you_name_it
DIRS="/etc /home /bin /sbin /usr/bin /usr/sbin /usr/local /var /your_directory"
ADMIN="email@your.domain.com"
FROM="admin@your.domain.com"
# 写入Sendmail的标头
echo "Subject: $HOSTNAME filesystem check" > /tmp/today.mail
echo "From: $FROM" >> /tmp/today.mail
echo "To: $ADMIN" >> /tmp/today.mail
echo "This is filesystem report comes from $HOSTNAME" >> /tmp/today.mail
# 报告目前正在执行的程式
ps axf >> /tmp/today.mail
# 档案系统检查
echo "File System Check" >> /tmp/today.mail
ls -alR $DIRS | gzip -9 > /tmp/today.gz
zdiff /tmp/today.gz /tmp/yesterday.gz >> /tmp/today.mail
mv -f /tmp/today.gz /tmp/yesterday.gz
# 寄出信件
sendmail -t /dev/null 2> /dev/null #上班前检查
不是应该是 “sendmain -v $ADMIN < /tmp/today.mail ”吗
