Simple Email Script

Shell Programming and Scripting
1

Hi All,

Im completely new to scripting but I was wondering can somebody show me how to write a bash script so that if any file enters a specific directory that an email gets sent?

I am running a few backups on a few different machines and rysncing them to a remote device, For each server I have a directory name of each server so when a new backup file is received by the backup device I want it to send me a simple mail saying that the backup device got it.

The backup device is a readynas 1100 and runs linux so theres no hassle running cron jobs and scripts etc

I have the backups named by date so the file names are different each time for instance

When this file is received i need a mail sent
/ns2/named-2013-03-13_0940.tar

The File name the next day will be
/ns2/named-2013-03-14_0940.tar

Thanks in advance

James

You can try with the following bash script but make sure you test it. There will be many more smart ways to do it.

#!/bin/bash
NOW=$(date +"%Y-%m-%e")
if ls *$NOW*
then
echo 'BACKUP DONE ' | mail -s backupreport ithelpdesk@enovatemedia.co.in
else 'file not found' | mail -s backupreport ithelpdesk@enovatemedia.co.in
fi

Thanks Kirfee

Is there somewhere i should enter where the files are in this script?

The output i am getting from this is :

ls: *2013-03-15*: No such file or directory
./rtapp1.sh: line 6: file not found: command not found
Null message body; hope that's ok

Im presuming that its because I didnt specify the directory

the directory is /RTAPP1/Dailybkup/

Sorry im completely new at this so i know I should add it but havent a clue where

replace line as follows;

ls /RTAPP1/Dailybkup/*$NOW*

Thanks Kirfee Im getting the hang of messing around with that script you gave me on other servers much appreciated. Think I will have to buy a book and teach myself,

I am having one issue on one server however is it possible to run yesterdays date in the script instead of todays date?

The issue I am having on one server is the backup runs close to midnight and sometimes it doesnt finish till after midnight so i was thinking if I can just see that the date before ran okay I can troubleshoot myself from there,

#!/bin/bash
NOW=$(date +"%e%m%y")
if ls /RTAPP1/Dailybkup/Dailybkup.$NOW.bz2
then
echo 'BACKUP Successfull RTAPP1' | mail -s BACKUP.Successfull.RTAPP1 support@xxx.com
else 'file not found' | mail -s Backup_Failed_RTAPP1_MOVE_TO_UNIX_QUEUE support@xxx.com

Never mind some googling around helped me come up with

#!/bin/bash
#NOW=$(date +"%e%m%y")
yest=$(date --date="yesterday")
echo "$yest"
yest=$(date --date="yesterday" +"%e%m%y")

if ls /RTAPP1/Dailybkup/*$yest*
then
echo 'BACKUP Successfull RTAPP1' | mail -s BACKUP.Successfull.RTAPP1 support@xxx.com
else 'file not found' | mail -s Backup_Failed_RTAPP1_MOVE_TO_UNIX_QUEUE support@xxx.com
fi

thanks for your help
