Parse a string as a command
I've a problem parsing a string as a command:

Consider script stefano.sh as following:
Code:
#!/usr/bin/sh

txtshell="./parser.sh /ews/MyEventHandler/data/handler/StopAndMail.php eventid=StopAndMail.MVIN.6300 lot_number=1122FXB facility=EWSF3 'mailto=prova.prova@nohost.com, prova.test@nohost.com' stop_oper=3000 stop_category=VISSPEC stop_step=MVIN 'message=Hold per QA (O.Tavilla)'"

$txtshell

The 'txtshell' is a text variable with the shell to be executed and relevant parameters (some of them included by single-quote and with white space inside

Then, the parser.sh is this one:
Code:
#!/usr/bin/sh
for param
do
        echo "Parameter: $param"
done

I was expecting this output

Code:
Parameter: /ews/MyEventHandler/data/handler/StopAndMail.php
Parameter: eventid=StopAndMail.MVIN.6300
Parameter: lot_number=1122FXB
Parameter: facility=EWSF3
Parameter: 'mailto=prova.prova@nohost.com, prova.test@nohost.com'
Parameter: stop_oper=3000
Parameter: stop_category=VISSPEC
Parameter: stop_step=MVIN
Parameter: 'message=Hold per QA (O.Tavilla)'

...while I had this...

Code:
Parameter: /ews/MyEventHandler/data/handler/StopAndMail.php
Parameter: eventid=StopAndMail.MVIN.6300
Parameter: lot_number=1122FXB
Parameter: facility=EWSF3
Parameter: 'mailto=prova.prova@nohost.com,
Parameter: prova.test@nohost.com'
Parameter: stop_oper=3000
Parameter: stop_category=VISSPEC
Parameter: stop_step=MVIN
Parameter: 'message=Hold
Parameter: per
Parameter: QA
Parameter: (O.Tavilla)'

What's wrong? Can anybody help me?!?

Thanks in advance!

script.sh:
Code:
#!/bin/sh

txtshell=`./parser.sh /ews/MyEventHandler/data/handler/StopAndMail.php \
eventid=StopAndMail.MVIN.6300 lot_number=1122FXB facility=EWSF3        \
'mailto=prova.prova@nohost.com, prova.test@nohost.com' stop_oper=3000  \
stop_category=VISSPEC stop_step=MVIN 'message=Hold per QA (O.Tavilla)'`

echo "$txtshell"

parse.sh
Code:
#!/bin/sh
for param
do
        echo "Parameter: $param"
done

Code:
% ./script.sh
Parameter: /ews/MyEventHandler/data/handler/StopAndMail.php
Parameter: eventid=StopAndMail.MVIN.6300
Parameter: lot_number=1122FXB
Parameter: facility=EWSF3
Parameter: mailto=prova.prova@nohost.com, prova.test@nohost.com
Parameter: stop_oper=3000
Parameter: stop_category=VISSPEC
Parameter: stop_step=MVIN
Parameter: message=Hold per QA (O.Tavilla)

PS
I'm afraid I have not understood your code at once. Change $txtshell to eval "$txtshell" and your script should work.
