Pipe into another script

[Dr Small]

I have written a very short script in haste, and basically I want to pipe other commands into it. Whatever I pipe into it, I want to be able to nab that command and add it as a variable to my script.

Here is the current script:

#!/bin/bash

to="drsmall@mycroftserver.homelinux.org"
subject="Server Emergency"

message=$(echo "Mycroft Server Emergency.\n\nLast command:\n"$0 "\n\n\nReason:\n"$1)
echo -e $message | mail -s "$subject" $to


I have $0 in there for the script name, but when I get the email, in tells me the location of my mailer script, instead of the command I piped into it.

So the basic question, how can I read the command (not the stdin) in my script that I piped through it?

#!/bin/bash
cat << EOF | mail recipient@email.add.com
Mycroft Server Emergency.
Last command:
$0
Reason : $1
EOF

That has the same effect:


Mycroft Server Emergency.
Last command:
/home/drsmall/bin/mailer
Reason :


And I ran:

free -h | mailer

Just for a test. Well, thanks anyhow for trying.

#!/bin/bash
echo "script name: $0"
while read var
do
echo "input line: " $var
done

output:


# df | ./mailer.sh
