How to include command results to send to admins via mail

deibertine · 07-16-2010, 01:22 PM

Hi all,
I was wondering on how to include my command results in a script?
Basically what the script does is it checks the status of a service within the linux server, then sends an email when done.
I want to include the results of my status check to my mail when sent.

i.e.
service dhcp3-server status
Status of DHCP server: dhcpd3 is running. <---this I want to include in the mail that is sent out via script.

Please advise.

Cheers!

Without knowing more about your script specifically...

Code:

service dhcp3-server status | mail -s dhcp3-server deibertine@deibertine.local

try this:
service dhcp3-server status | mailx -s "system status" user@domain.com

So if i want to include the result of my command:
service dhcp3-server status

Result:
Status of DHCPServer: dhcp3 is running

How do i capture the "result" to include in my mail being sent out?

you could create a script

Code:

echo Status of DHCPServer:  > temp.txt
service dhcp3-server status >> temp.txt

Then cat temp.txt in the mail

How do you "cat" the log file and include in the mail?

By 'cat' the log file he means send it to stdout, then pipe it to the 'mail' command.

For example:

cat temp.txt | mail -s "Mail Subject" user@domain.com

This will make the contents of 'temp.txt' the body of your email.
Hope this helps,
