In other words, nothing is returned.

To Don Cragub :

"should also work with no problems. But..."

But does not :

Code:
duntstudb51:root:/home/jc # cdeset=$(su - db2inst1 -c "db2 get db cfg" | grep -i 'code page')
duntstudb51:root:/home/jc # echo $cdeste

duntstudb51:root:/home/jc #

But your explanation brings me a lot of interesting information...

Well guys, that's ok for me tonight. Late in France, have to go to bed, was called yesterday, for my on call period ;-)

Thank you so much for your help. Sincerly. I do appreciate.

Back tomorrow that is another day.

I can't explain why you aren't getting any output from the first command you have shown us above. But there is no surprise in the second set of commands providing no output. If you assign output to a variable named cdeset and print the contents of a different variable (cdeste) (that as near as well can tell has never been assigned any value), it is no surprise that the echo only produces an empty line as output.

Just for the fun of it, what operating system are you using? And, although you have said you are using the Korn shell, what shell is the login shell for root on your system?

To Don Cragun :

Sorry for this mistake. Unfortunatly, even after correction, the result is the same for the piece of code following :

Code:
duntstudb51:root:/ # cdeset=$(su - db2inst1 -c "db2 get db cfg" | grep -i 'code page')
duntstudb51:root:/ # echo $cdeset

duntstudb51:root:/ #

The OS is an IBM AIX 7.1 and the login shell is ksh.
