Set from address text in bash mail

Question

I am able to send mail from bash, but cannot change the from text, it currently comes up as 'root'.

I would like email clients to show the following text in the from field script on myserver.com ([email protected]).

How can I do this please?

emailsubject="$scriptname ($scriptver) log at $startdate"

if [ $errorcount > 0 ]; then
    emailsubject="ERRORS($errorcount) - ${emailsubject}"
fi

mail -s "$emailsubject" [email protected] < $logfile

Answer 1

If Your "mail" supports it, You may add custom headers using the -a switch like this:

mail -s "subject" -a "From: [email protected]" ...
