Hide output from expect

Question

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.

Does this help? http://stackoverflow.com/questions/681928/how-can-i-make-an-expect-script-prompt-for-a-password BTW this 夜弓 not that *叶公* :) — Kent, Jan 30 '13 at 13:24

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

using this command:

exec >log 2>&1

you can forward your output to a file or you can pass it to dev/null
