BASH - Send mail with an AttachmentThis requires uuencode, which is available in the package sharutils.
It uses the command line utility sendmail, and formats the smtp message as necessary to send an email and an attachment. We also have an article with just a basic bash sendmail script. #!/bin/bash #requires: basename,date,md5sum,sed,sendmail,uuencode function fappend { echo "$2">>$1; } YYYYMMDD=`date +%Y%m%d` # CHANGE THESE TOEMAIL="recipient@email.com"; FREMAIL="crondaemon@65.244.254.144"; SUBJECT="Daily Backup - $YYYYMMDD"; MSGBODY="Hello this is the message body"; ATTACHMENT="/home/joeuser/Untitled.png" MIMETYPE="image/png" #if not sure, use http://www.webmaster-toolkit.com/mime-types.shtml # DON'T CHANGE ANYTHING BELOW TMP="/tmp/tmpfil_123"$RANDOM; BOUNDARY=`date +%s|md5sum` BOUNDARY=${BOUNDARY:0:32} FILENAME=`basename $ATTACHMENT` rm -rf $TMP; cat $ATTACHMENT|uuencode --base64 $FILENAME>$TMP; sed -i -e '1,1d' -e '$d' $TMP;#removes first & last lines from $TMP DATA=`cat $TMP` rm -rf $TMP; fappend $TMP "From: $FREMAIL"; fappend $TMP "To: $TOEMAIL"; fappend $TMP "Reply-To: $FREMAIL"; fappend $TMP "Subject: $SUBJECT"; fappend $TMP "Content-Type: multipart/mixed; boundary=\""$BOUNDARY"\""; fappend $TMP ""; fappend $TMP "This is a MIME formatted message.
