我正在尝试对两个文件进行差异比较,如果它们不同,则发送电子邮件。以下是我的脚本,由于某种原因我无法运行。欢迎提出任何建议。
#!/bin/bash
# This script alert.sh runs every hour in cron
# Created march 15, 2018 Author Dave Taylor
# Variables
frm="[email protected]"
# For testing email and script
recipients="[email protected]"
# This is the Data file checked every Midnight for website results done by curdata.sh script. Results go to the curfile.fil
current=/scripts/results/curfile.fil
# This is the NEW data output file where website is checked every hour done by newdata.sh script. Results go to the datafile.fil
new=/scripts/results/datafile.fil
dpd=`cat /scripts/results/datafile.fil`
dte=`/bin/date`
# check if the contents of the file has changed since midnight.
if diff $current $new &>/dev/null
then
# Log it
echo "$dte" >> /var/log/datapod
echo "Data file is $dpd" >> /var/log/datafile
else
# Create the message
echo "Current STL Datafile has changed TO:$dpd" > /scripts/results/mesg
# send the email
mail -s "Alert Data File has changed" -r "$frm" $recipients < /scripts/results/mesg
sleep 3
#Now we update the current data file with the most up to date info.
cat /scripts/results/datafile.fil > /scripts/results/curfile.fil
fi

尝试这个:
#!/bin/bash
frm="[email protected]"
recipients="[email protected]"
current=/scripts/results/curfile.fil
new=/scripts/results/datafile.fil
log=/var/log/datafile
msgfile=/scripts/results/mesg
dte=`/bin/date`
diff $current $new &>/dev/null
if [ $? -eq 0 ]; then
echo "${dte}: Data file is: $new " >> $log
else
echo "Current STL Datafile has changed TO: " > $msgfile
cat $new >> $msgfile
mail -s "Alert! Data File has changed" -r "$frm" $recipients < $msgfile
sleep 3
cat $new > $current
echo "${dte}: Data file has changed. Sent mail to $recipients" >> $log
fi
