Hide output from expect
提问by yegong
Here's part of an expect script
这是预期脚本的一部分
#/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.
它从 kwalletcli 读取密码，并存储在变量中passwd。所以我可以用这个连接到服务器passwd。
However, the output of kwalletcli is pass through expect and show on console. How can I hide that.
但是，kwalletcli 的输出是通过 expect 并在控制台上显示的。我怎么能隐藏呢。

Try adding
尝试添加
log_user 0
to your script. That should turn off the display to stdout.
到你的脚本。那应该关闭显示到标准输出。
If you want to turn it on again for the "do some thing" part of the program, re-enable it
如果您想为程序的“做某事”部分再次打开它，请重新启用它
log_user 1

using this command:
使用这个命令：
exec >log 2>&1
you can forward your output to a file or you can pass it to dev/null
您可以将输出转发到文件，也可以将其传递给 dev/null
