"exec" command. Stopoutput to file.
I have a script (ksh, Linux) which is about 500 lines and this is only a small requirement. Below is an example of my requirement.
Code:
 
FunctionThis(){
  echo "You are in this. Goes to log"
}
FunctionThat(){
  echo "You are in That. Goes to log"
}
FunctionScreen(){
  echo "You are in Screen. Goes to screen."
  echo "Press ^c to exit"
  sleep 60
}
################
# Main
################
exec > Outlog1.txt 2>&1
FunctionThis
FunctionThat
exec > > 2>&1
FunctionScreen

1. Now all the outputs are going to .log file.
2. I want "FunctionScreen" output to be on the screen.
Not into the log file.
That is, I thought
HTML Code:
exec > > 2>&1
will disable writing to log file.
Can you help me please?
