Do you really need to assign O1 O2 and O3 on the command line?

Why not simplify the command and assign them first:

Code:
O1='$input'
O2='data2'
O3='data3'
./executable > /send/output/to/log`date`.txt

How will I read the options (O1,O2,O3) to the command if I do it this way?

Ah, I see what you're saying. The problem is "O1 O2 O3" are literal stings that must go with the command. Let me play around with this a little to see if I can come up with something.

try using the export command:

export O1 O2 O3

Like this?

Quote:
O1='$input'
O2='data2'
O3='data3'

export O1 O2 O3 ./executable > /send/output/to/log`date`.txt

No either:
Code:
O1='$input'
O2='data2'
O3='data3'
 
export O1 O2 O3 
./executable > /send/output/to/log`date`.txt

or
Code:
O1='$input'
O2='data2'
O3='data3'
 
export O1 O2 O3 ; ./executable > /send/output/to/log`date`.txt

Nah. That doesn't appear to be working. Although all the errors have gone away, it's not running the ./executable or logging to the log directory. The end command has to be "O1 O2 O3 ./executable ..."

I've tried a few options but I can't get this to work.

Should I be using a variable with the export?

export O1 O2 O3
$O1 $O2 $O3 ./executable > /send/output/to/log`date`.txt

You are putting in extra quotes in front of it that foul it up.

Code:
O1="$input" O2='data2' O3='data3' ./executable > "/send/output/to/log`date`.txt"
