Shell Programming and Scripting

Is there a way to alter the file descriptor for stdout.?

sample:

#!/bin/ksh
exec 1>file
exec 2>file

echo hi --------->This will go to file

print -u4 "come statement"---->I want to make the file descriptor 4 to point to stdout.

The reason is ,I have a script which has lot of db2 and oracle execution steps.I want to redirect those exe output to some file and the user should see only those messages I print.

Hi.

Direct your new file descriptor to stdout, before redirecting stdout to a file

Code:

exec 4<&1
exec 1>file
