Shell Programming and Scripting

I'm trying to write a simple script to send e-mails using ksh on a Sun Solaris box.

The script is as follows:

# Arguments: $1 = Command Type i.e. mailx etc
# $2 = Subject
# $3 = From
# $4 = To
# $5 = Mail File
#
# IF MAIL TYPE IS mailx THEN DO:
#
if [ "$1" = "mailx" ]
then
mailx -s $2 -r $3 $4 < $5
fi

The problem is this. The subject input paramater i.e. $2 can be a full sentence i.e. "Test E-Mail". So how do I get a ksh script to read in a sentence and see it as a single input paramater and not multiple paramaters.

This script is being run from within a 4GL program and the input paramaters are being passed in from DB fields.

Is there a unix replace command I could use. I thought about passing the subject in as follows "Test_E-Mail" and the perhaps replacing the underscore "_" with a space " ".

Is that possible?

Cheers!

Hi,
You can provide the subject within double quote ".

Example:

cat arg.ksh

Code:

#!/bin/ksh
echo $1 $2 $3 $4 $5

Code:

./arg.ksh mailx "Test Email" a@b.com d@e.com File

Code:

Output :
  mailx Test Email a@b.com d@e.com File

Does this answers your query.

Actually I had just figured that out myself. If I use single quotes from the 4GL and then change the mailx part of the script to take in literal double quotes it works fine.

Cheers again,
