Scripted Email

Used to send email to list of people from flat file. Usually when sending from server you want the reply-to set correctly so the replies go to a proper email account.

The input file is cre.txt and has the following format

• Header: Username Password Email
• Rows: userid password email
• Fields are space delimited

Sample file

Username Password Email
hjames N8dseRzx8l someone1@example.org
itom 08sdfssRPd someone2@example.org
klucy 1eh4g6y88 someone3@example.org

Things to update in script are

• input file location (input)
• Subject (subject1)
• Body as appropriate
• replyto field

The tr command is optional. In case the file arrived from DOS/WINDOWS it may have funny characters

#!/bin/bash
cat cre.txt | tr -d '\015' > cre1.txt
input=cre1.txt
subject1="Some Subject"
while read -r line
do
    IFS=" " read -r f1 f2 f3 <<<"$line"
    if [ ! $f1 = "Username" ]; then
        echo "Emailing $f3 ..."
        body1="You Userid is $f1 and Password is $f2"
        echo $body1 | mailx -s "$subject1" -S replyto=someuser@example.com "$f3"
    fi
done <"$input"
