I tried the following script on unix server . It is designed to put a number of messages to a queue. I want to assign the content of the SAMPLE variable to each message as it will have the message number attached. However when I run testdriver i get following error
" ./testdriver[7]: Message number 1: cannot open": Any ideas?? 
vi testdriver
"testdriver" 13 lines, 328 characters
VAL=1
SAMPLE=`echo Message number $VAL`
echo the date is
date
while [ $VAL -lt 6 ]
do
amqsput QName QMgrName < $SAMPLE
VAL=`expr $VAL + 1`
sleep 1
done
VAL=`expr $VAL - 1`
echo $VAL records were put to queue QName on QMgrName |

| Maybe amqsput is not in the PATH |

I believe this is what the problem is.
When you issue amqsput and supply $SAMPLE as input, amqsput assumes this $SAMPLE to be a file rather than stdin. As you cannot send in text the way you are trying to. And since amqsput is NOT coded to handle such stuff, there are 2 options for you that i can see easy enough to achieve.
-Instead of calling amqsput from this script that you posted here, add each line of message that you wish to put, Message number 1, etc, and output this to a file. Call Amqsput from command prompt and then supply this filename that consists of all those Message number 1, 2,....
-Modify the amqsput sample app to put messages with the text you want in a loop. Belive me, it would be much faster and easier to do this, than to try and fix your little script. :)
Good luck.
Cheers

I'm a little confused.
It seems that AMQSPUT doesn't like having stdin redirected from <.
But it works just fine with |.
So,
| Code: |
| $SAMPLE | amqsput QName QMgrName |

Jeff, my take on that would be, since "|" sends output from something into something, the RHS expression to "|" takes input line by line as opposed to a complete file when you are using <.
For example:
Ps | grep hello
Every output of Ps is sent as input to grep command which then evaluates the condition that you put up, which is, search for string "hello". So, you can term this like an interpretor, if i can say so. :)
As opposed to stdin which takes the whole file into account as in example of amqsput.
I havent tried with | and hence am not sure if it works or not. But as you mentioned if it does work, then the above could be the theory behind it.
Just my 2 cents. :)
Cheers
