备份一个发邮件的脚本

#!/bin/sh

function echo_help()
{
    echo "Usage:"
    echo "sh mailto.sh -to mailaddr -file messagefilename [-from frommailaddr] [-subject mailsubject] [-fname shownam    e] [-tname toshowname]"
}

email="[e-mail]"
emailname="cmtools monitor"
messagebody="tmp.tmp"
from="[e-mail]"
fromname="cmtools monitor"
subject="cmtools running statistic report"

until [ $# -eq 0 ]
do
tmpV=$1

if [ $tmpV = "-from" ] ; then
shift
tmpV=$1
from=$tmpV
elif [ $tmpV = "-to" ] ; then
shift
tmpV=$1
email=$tmpV
elif [ $tmpV = "-subject" ] ; then
shift
tmpV=$1
subject=$tmpV
elif [ $tmpV = "-file" ] ; then
shift
tmpV=$1
messagebody=$tmpV
elif [ $tmpV = "-fname" ] ; then
shift
tmpV=$1
fromname=$tmpV
elif [ $tmpV = "-tname" ] ; then
shift
tmpV=$1
emailname=$tmpV
elif [ $tmpV = "--help" -o $tmpV = "-h" ] ; then
echo_help
exit 1
fi

shift
done

if ! test -f ${messagebody} ; then
echo "${messagebody} not exists!"
echo_help
exit 2
fi

echo "begin send..."

echo -e "To: \"${emailname}\" <${email}>\nFrom: \"${fromname}\" <${from}>\nSubject: ${subject}\n\n`cat ${messagebody}`" | /usr/sbin/sendmail -t

echo "send OK."

另外一个维护脚本:

 

echo > old.txt
echo > new.txt
while true
do
echo $$ > pid.txt
./check > new.txt
#data=`cat new.txt`

if [ -s new.txt ]
then

    res=`diff new.txt old.txt`
    if ! [ -z $res ]
    then
        ./mail.sh -to [e-mail] -file new.txt
        cat new.txt > old.txt
    fi
else
        #res=`cat old.txt`
        if [ -s old.txt ]
        then
            #echo "every thing is ok" > new.txt
            #./mail.sh -to [e-mail] -file new.txt
            echo > new.txt
            echo > old.txt
        fi
fi
sleep 600
done
