Question

In a shell script i have

LOG=/my.log
exec 1>>$LOG
exec 2>&1

which redirects the output in shell script. Now the problem is in the following

LOG=/etc/security/aixpert/log/aixpert.log
exec 1>>$LOG
exec 2>&1

#some codes

print "I want this on cmd output not in log"

#I want rest of the output redirected to log as usual

How can i do this??

The key is to clone stdout going to the console to an arbitrary fd (I chose 3) before your redirect it to your log. Whenever you want to send output to the console you just redirect fd 1 back to fd 3 with >&3 for that one command

LOG=/etc/security/aixpert/log/aixpert.log

exec 3>&1 >>"$LOG" 2>&1

#some codes

echo "I want this on cmd output not in log" >&3

#I want rest of the output redirected to log as usual
