Script to email based on the user

Mark Mitchell — Wed, 06 Sep 2000 14:57:05 GMT

I am having trouble making a script to use elm to e-mail to a user some files.

The problem is that I want to put a variable in so that the script does basically a "whoami" for the e-mail address. That way who ever fires it off will get the message sent back to their e-mail offsite.

Any ideas?

instead you can simply add an alias to the /etc/mail/aliases file. eg; in this file put an entry;
root : @
jim : jim@hp.com
then run newaliases, from now on all email to root or jim it will go to the address specificied.

If you want to use a script you can set a variable which is the result of a whoami command by doing;
USER=`whoami`
This will return a value such as root.
Then in your script you can mail something by going;
echo test | mailx -s"subject" $USER

that part is already done, I am talking about a variable in the script so that it does a whoami and gets "jim" and uses it. Then the aliases file will resolve jim to jim@hp.com and send it to the exchange server. That way the user just has to fire off an executable in the application and the script will do the rest.

But the mail came back as user whoami unknown

when you go> USER=`whoami`
you must use backquotes, not forward quotes. The backquotes mean execute the command and put the results into the variable.
eg. after USER=`whoami`;echo $USER I get the answer root

Mark, it depends on if your using UNIX mail IDs with the UNIX doamin name or something like an Exchange address which may be different from your UNIX e-mail address.

If you want to use an e-mail address NOT corresponding to your UNIX id then use the .forward file in the home directory. Now grab the UNIX id from whoami and simply tack on your UNIX domainname. If you have a .forward file in the home directory then UNIX will try and use it.

If you want to use the aliases file you will have to take it one step further. If you don't use NIS, you will have to interogate the /etc/mail/aliases file or if your using NIS, interogate the aliases map with ypcat.

The "whoami" and "who am i" will produce different outputs.

Set the variable: export WHOISIT=`whoami`
cat file | mailx -s TESTING" root $WHOISIT

You may want to be sure aliases or .forward files are in use as well.

Now it is starting to take shape. The only thing is that I had to cut and paste, how did you make the backquote charicter?

Hi,
You may use `whoami` in command line to refer your own user name. e.g
elm -s Testing Mail `whoami' < /tmp/mailfile

The backquote char is the one below the ~ character usually in the top left corner

Here is a perl version of it ...

#!/bin/perl
# This should match the mail program on your system.
$mailprog = '/usr/lib/sendmail';
$recipient = 'youremail@yourdomain.com';
$email = 'bob@hp.com';

# Now send mail to $recipient
open (MAIL, "|$mailprog $recipient") || die "Can't open $mailprog!n";
print MAIL "From: $emailn";
print MAIL "Subject: ITRCnn";
close (MAIL);

Hi,

if you use posix shell (/sbin/sh) or korn shell (/usr/bin/ksh) you can do:
USER=$(whoami)
this will put the output of the executable whoami into the variable USER.

Mark,

on a USASCII you find a backquote ` left of "1", a singlequote ' left of enter.
on a SwissGerman backquote is Shift+ left of backspace, singlequote one more to the left.

Thanks everyone, I wanted to create a script that would e-mail you the result to Microsoft exchange. I basically use the etc/aliases to resolve the name. Here is the working version. I created the wri file because I wanted the output to open in Wordpad first so users didn't have to figure it out. I know that it looks dirty, but I am still working on it.

USER=`whoami`
cp report.wri ~/report.wri
< ~/report.wri
pg $1 > ~/report.wri

if [ ! -d ~/Mail ]; then
mkdir ~/Mail
fi

if [ ! -d ~/.elm ]; then
mkdir ~/.elm
fi

#!usr/bin/sh

echo "[include ~/report.wri application/octet-stream base64]" |
elm -s "report " $USER
