converting a bash script to a oneliner

I am having difficulties converting this bash script to a oneliner.

Code:

{
    echo Subject: This is the logfile
    cat /tmp/logfile
} | ssmtp my@email.com

I tried a few things, but every time either the subject or log file are not included in the the email.

How can I do this?

Pretty much just by changing the newlines to semicolons.

Code:

{ echo Subject: This is the logfile; cat /tmp/logfile; } | ssmtp my@email.com

Blindly converting would leave you with one extraneous semicolon preceding the "echo" command.

You can cat stdin with logfile

Code:

echo Subject: This is the logfile | cat - /tmp/logfile | ssmtp my@email.com
