Many Thanks for the response Andryk.
A few questions ...
I had worked with a sample of 3 mails.
1) I am not sure is `seq150` works in Unix. So I had used
for i in 1 2 3 instead of
for i `seq 3`in the 1st line of your script.
2) In your script, in line no - 3,
echo s $i file.$i >> forpipe, I am not sure why was $i also echoed. For e.g. if there are 3 mails, then the file "forpipe" would look
like
s 1 file.1
s 2 file.2
s 3 file.3
Now when I had run your script, I got the following files created - file.1, fil2.2,file.3,1,2,3.
When I removed $1 from the script (line no 3), I got 3 files - file.1,file.2 and file.3.
3) The script runs fine if the number of mails = contents in the file forpipe.
for e.g.
the contents in the file file - forpipe is
s file.1
s file.2
s file.3
x
The number of mails = 3.
However when the number of mails = 4, and there are 3 files listed in forpilpe, the files are still created, but the mail 1-3 are not deleted. Am not sure why.
In my case, the mails can come any time, and a new mail could have come after the creation of forpipe, while the mails are being processed. I cannot process the email again, because each email is expected to be unique.
Is there a way out ?
Apologies for being so lengthly ... I hope I am making sense.
Many Thanks.

escape(1) Mail Avenger 0.8.3 escape(1)
NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`
SEE ALSO
avenger(1),
The Mail Avenger home page: <http://www.mailavenger.org/>.
BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
