Dynamic command with quotes
I have a shell script which composes a dynamic command (DataStage application):

Code:
conn="/DS/Ascential/DataStage/DSEngine/bin " 
paramlist=" -run -jobstatus -wait -mode NORMAL -param JOB_ID=98246 -param PREVRUNDT='2010-03-20 18:00:00' -param CURRRUNDT='2010-03-21 18:00:00'" 
jobinfo=" APPPRJ Load_Target" 

$conn $paramlist $jobinfo

This does not work and says:

HTML Code:
Invalid arguments: dsjob -run 
                        [-mode <NORMAL | RESET | VALIDATE>] 
                        [-param <name>=<value>] 
                        [-warn <n>] 
                        [-rows <n>] 
                        [-wait] 
                        [-opmetadata <TRUE | FALSE>] 
                        [-disableprjhandler] 
                        [-disablejobhandler] 
                        [-jobstatus] 
                        [-userstatus] 
                        [-local] 
                        [-useid] 
                        <project> <job|jobid>

But it works if I have:

Code:
Code:
conn="/DS/Ascential/DataStage/DSEngine/bin/dsjob" 
jobinfo=" APPPRJ Load_Target" 

$conn -run -jobstatus -wait -mode NORMAL param JOB_ID=98246 -param PREVRUNDT='2010-03-20 18:00:00' -param CURRRUNDT='2010-03-21 18:00:00' -warn 50 $jobinfo

The list of parameters are dynamic so I'd like to put them in a string for readability of the code. I am really puzzled why it is not running when I am using variables.
The quoted strings PREVRUNDT='2010-03-20 18:00:00' are the culprit. When I store them in a variable, in this case $paramlist, the code does not work. But if I put them directly as in second code, they run well.

Perhaps try...
Code:
paramlist=' -run -jobstatus -wait -mode NORMAL -param JOB_ID=98246 -param PREVRUNDT='\''2010-03-20 18:00:00'\'' -param CURRRUNDT='\''2010-03-21 18:00:00'\'''

Thanks, Ygor, but the formed command becomes:
Code:
DS/Ascential/DataStage/DSEngine/bin -run -jobstatus -wait -mode NORMAL -param JOB_ID=98246 -param PREVRUNDT='\''2010-03-20 18:00:00'\'' -param CURRRUNDT='\''2010-03-21 18:00:00'\'' APPPRJ Load_Target

which is also invalid.
