I do this all the time. Since this is your first time, maybe an example
will help:
cd /var/log
grep -i error messages |mail -s "message log errors" [EMAIL PROTECTED]
The results of the grep command are piped over to the mail command.
In the mail command the "-s" indicates the subject of the mail.
The mail is sent to [EMAIL PROTECTED], and is sent from whoever the local
user happens to be.
You can send to multiple addresses:
echo "Hi" |mail -s "test" -c [EMAIL PROTECTED] [EMAIL PROTECTED],[EMAIL PROTECTED]
This tiny message goes out with the subject "test" and is sent to:
[EMAIL PROTECTED] and [EMAIL PROTECTED] The message is also cc'ed to
[EMAIL PROTECTED]
I do this sort of thing all the time. Here is a standard program that I
run hourly on most servers... it's a simple volume and inode size test:
MSG=`df -ah |grep 9[56789]%`
if [ ! "xxx" == "xxx$MSG" ]; then
echo $MSG |mail -s "Volume Space Low on Server: GDM1" [EMAIL PROTECTED]
fi
#
MSG=`df -iah |grep 9[56789]%`
if [ ! "xxx" == "xxx$MSG" ]; then
echo $MSG |mail -s "Inode problem on Server: GDM1" [EMAIL PROTECTED]
fi
