Hi Don,

Here the output below.

OK. Run the command:
Code:
tty

which will give you something like /dev/terminal. Then run the command:
Code:
ps -t terminal

where terminal is the string after /dev/ in the output from the tty command and show us the output from that.

Hi Don,

Please find the below:

Code:
tty
/dev/pts/20

Code:
ps -t /pts/20
   PID TTY         TIME CMD
 13637 /pts/20     0:00 ps
 29563 /pts/20     0:00 csh

Do you see any inconsistency here between your claim that you are running ksh and the output above that clearly shows that you are running csh as your shell?

To change from running csh to actually run ksh, issue the command:
Code:
exec ksh

then, try one of the commands that was suggested above in this thread that was failing due to csh command history substitutions.

Yes Don. I did not understand why it showed csh in there while i am working in ksh shell.
Anyways, i will try as you suggested and will let you know the results.

Thanks & Regards,

Hi Don,

Just need clarification. when i give the command exec ksh, the prompt chnaged to $. where as earlier it is ->.
So the shell till now i worked is csh , is it ? Now with the command exec ksh i have moved to ksh shell. Am i correct ?

Hi Don,

I have given the command exec ksh. Then i tried all of the codes suggested by each one of you. I did not get any error like earlier but there was no required modifications done on my Input(Output is same as the Input).

could you please suggest me how can i proceed further on this ?

Thanks & Regards,

Again: difficult to believe. I'd sooner believe that all of the proposals have been tested before being posted here. Please give some evidence of your assertion by posting those commands running and their output.
