从stdin读取数据时，如何防止`expect'在EOF退出? [英] How can I prevent `expect` from exiting at EOF when reading data from stdin?

问题描述

当我运行echo "passphrase" | expect expect.exp "hostname"时，一切正常，但是expect立即退出.

When I run echo "passphrase" | expect expect.exp "hostname", everything works fine, but expect exits immediately.

#!/usr/bin/expect

set passphrase [gets stdin]

set hostname [lindex $argv 0]

spawn ssh admin@$hostname
expect "passphrase"
send "$passphrase\r"
expect "admin@$hostname"
send "clear\r"
interact

当 stdin 不是tty时，

推荐答案

interact不起作用.您可以像主机名一样将密码作为命令行选项传递.

interact does not work when stdin is not a tty. You can pass the password as a command line option, just like the hostname.
