使expect脚本传回返回值

使expect脚本传回返回值

1、使用expect示例：

spawn $SPAWN_CMD

expect {

        -re "Enter password for new role:" {

                send "$PWPROMPT\n"

                exp_continue

        } -re "Enter it again:" {

                send "$PWPROMPT\n"

                exp_continue

        } -re "Password(.*)" {

                send "$PASSWORD\n"

                exp_continue

        } -re "Password(.*):" {

                send "$PASSWORD\n"

                exp_continue

        } eof

}

2、返回值

spawn true

expect eof

catch wait result

exit [lindex $result 3]

Exits with 0.

***

spawn false

expect eof

catch wait result

exit [lindex $result 3]

Exits with 1.
