Shell Programming and Scripting

Hi rbatte1
U r correct.i should be more specific.at present this script can send max 2 attachment at a time.but issue here is we can not modify the script all time.once we give it to our boss,he can not changes again and again.Before submitting the script we should make it proper. So script should automatically ask user these many files are available under this particular Folder and which all file you want to attach them with mail.e.g.

If you want to magically guess at which files in your Desktop directory are intended to be attachments, it won't be easy (unless you can explain and implement the magic). If you are willing to move all of the files that you want to be treated as attachments into a directory in your Desktop directory (in the following example, that directory is named attachments), you might want to try something like:

Code:

#!/bin/bash
ATTACHMENT_DIR="/home/sreenivasa/Desktop/attachments"
ATTACHMENTS=
BODY_FILE="/home/sreenivasa/Desktop/Testing.txt"
SUBJECT="linux mail send attachment example"
TO_LIST="rajnikant875@gmail.com,sinha6315@gmail.com,rajnikant@gytechs.com"

# Gather list of attachments:
for file in "$ATTACHMENT_DIR"/*
do	[ ! -f "$file" ] && continue
	ATTACHMENTS="$ATTACHMENTS -a \"$file\""
done

# Send the message.
mail -s "$SUBJECT" "$ATTACHMENTS" "$TO_LIST" < "$BODY_FILE

Note that the text marked in red above serves two purposes:Note also that I renamed the variable CC_LIST to TO_LIST because the e-mail addresses in that list will be on the To: list in the mail message that is sent; not on that message's Cc: list.

Thanks Don Cragun for quick reply.
i am trying to run this script but it is unable to attach any kind of files from that particular folder.it is sending mail but without any attachment.
My requirement is like, script should attach all files from that particular folder.
One thing i did not understand what is use of variable ATTACHMENTS and file.

Can u please brief me.

Thank u
Rajnikant

In the manual page for mail on your server, do you have the -a flag? (not the same as the -A flag)

If not, then this will not work.

Hi Robin,
Note that Rajnikant said that the script in post #1 in this thread was working to send mail with a single attachment (using the mail -a option). I don't know of any versions of mail that accepts a -a option that won't accept multiple -a options.
Hi Rajnikant,
The for loop in my script executes the commands inside the loop once for each file in the directory /home/sreenivasa/Desktop/attachments. Each time it executes the commands in that loop, the shell variable file will be set to the name of one of the files in that directory. For every regular file it finds in that folder it adds -a and the name of that file (in quotes) to the shell variable ATTACHMENTS which is then used in the mail command to include those files as attachments to the message it sends.

To avoid sending unwanted mail while we are testing, please change:

Code:

mail

on the last line of your script to:

Code:

echo mail

Then show us the output you get from running the commands:

Code:

ls -l /home/sreenivasa/Desktop/attachments
     and
od -bc < your_script_name
     and
bash -xv your_script_name

where your_script_name is the name of the file containing your script.

Hi Don Cragun
u asked me to run the script and few commands.i ran it and attached it with this message.please have a look at Attach Files.

Thank U
Rajnikant

Hi Rajnikant,
In the future, when we ask for the output you get from running a command; please show us the output as text as it appears on your screen (presumably in a fixed width font as provided by CODE tags in the body of the post), not a Microsoft Word document given as an attachment using a variable width font and adding unwanted page breaks that hides much of the clarity in the output we need to see to help you.

I suggested that you should have:

Code:

mail -s "$SUBJECT" "$ATTACHMENTS" "$TO_LIST" < "$BODY_FILE"

as the last line of your script. Instead of that line, you used:

Code:

mail -s "$SUBJECT" "$ATTACHMENTS_DIR" "$TO_LIST" < "$BODY_FILE"

The trace from running your script clearly shows that it correctly set the variable ATTACHMENTS to include eight attachments, but you didn't expand that list in your invocation of mail. Instead you expanded the variable ATTACMENTS_DIR (which is never defined by your script and, therefore, expands to an empty string throwing away all of the work the script did to get your desired attachments).
