Sendmail で添付ファイルを送るバッチファイル（メモ）

備忘録です。

あらかじめ、attached.tar.gz のように tarボールで固めておいたファイルを xxxx@gmail.com 宛てに送ります。

念のため tar の圧縮の方法を書いておくと

# tar の圧縮
$ tar cfvz attached.tar.gz attached/

です。

あとは、以下のスクリプトを実行するだけ

#/bin/sh

# commands.
SENDMAIL=/usr/lib/sendmail
ECHO=/bin/echo
GZIP=/bin/gzip
CAT=/bin/cat
RM=/bin/rm

# attachment file info.
ATTACH_FILE=attached.tar.gz
ATTACH_PATH=/tmp/$ATTACH_FILE

# mail head settings.
MAIL_BODY=/tmp/mail_body.txt
MAIL_FROM=xxxx@gmail.com
MAIL_TO=xxxx@gmail.com
MAIL_SUBJECT="ATTACHMENT FILE TRANSFER."
MAIL_BOUNDARY=`date +%Y%m%d%H%M%N`

TIME_STAMP=`date +"%Y-%m-%d %H:%M:%S"`

# attachment file move.
mv ./${ATTACH_FILE} /tmp
cd /tmp

# make body.
$ECHO "Attached file is created at ${TIME_STAMP}" > $MAIL_BODY

# send mail.
