隐藏期望的输出 [英] Hide output from expect

问题描述

这是期望脚本的一部分

#/usr/bin/expect 

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

# do some thing
# ...

它从kwalletcli读取密码，并存储在变量passwd中.因此，我可以使用此passwd连接到服务器.

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

但是，kwalletcli的输出是通过Expect传递并在控制台上显示的.我怎么藏起来.

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

推荐答案

尝试添加

log_user 0

到您的脚本.那应该关闭显示到标准输出.

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

如果您想为程序的做某事"部分再次打开它，请重新启用它

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

log_user 1
