Answer 1

If you are interested in pure Expect based way, then you should use log_user.

#!/usr/bin/expect -f
log_user 0; # Disabling logging to user window
log_file -a -noappend scp_log.txt
spawn bash -c "scp /home/abc/pdf/105784/*.pdf [email protected]:/home/labdb2/Desktop/l/" 
expect {
  -re ".*sword.*" {
   exp_send "password@\r"
  }
}
interact

If you want to enable logging to user, then you can use log_user 1 to do the same.

IO redirection is a thing you want to use:

spawn bash -c "scp /home/abc/pdf/105784/*.pdf [email protected]:/home/labdb2/Desktop/l/ &> scp_log.txt" 

or just simply call the script as

./exp_test.sh &> scp_log.txt
