Hide output from expect

Here's part of an expect script

#/usr/bin/expect 

spawn -noecho kwalletcli -f Passwords -e keyofmypassword
expect ".*"
set passwd $expect_out(buffer)

# do some thing
# ...

It read password from kwalletcli, and store in variable passwd. So I can connect to the servers with this passwd.

However, the output of kwalletcli is pass through expect and show on console. How can I hide that.

Solution

  • Try adding

    log_user 0

    to your script. That should turn off the display to stdout.

    If you want to turn it on again for the "do some thing" part of the program, re-enable it

    log_user 1
