linux - 期望+在期望脚本中更改目录

Question

我们创建以下简单的 expect 脚本以运行 netdata-installer.sh

预期脚本是:

#!/usr/bin/expect

set timeout 20
send "cd /tmp/netdata\r"
spawn "bash netdata-installer.sh"

expect ">" { send "\r" }
interact

关于 netdata-installer.sh 的几句话:

为了运行 - netdata-installer.sh ，我们需要从工作目录 - /tmp/netdata 运行它，这就是我希望使用以下内容:

send "cd /tmp/netdata\r"

然后在我使用的expect脚本中:(为了执行ENTER，这样我们就开始了netdata的安装)

expect ">" { send "\r" }

到目前为止，一切似乎都很完美，但是当我们运行 expect 时，我们得到:

# ./exp.sh
spawn bash netdata-installer.sh
couldn't execute "bash netdata-installer.sh": no such file or directory
    while executing
"spawn "bash netdata-installer.sh""
    (file "./exp.sh" line 5)
You have new mail in /var/spool/mail/root

似乎期望脚本没有将工作目录更改为cd/tmp/netdata

那我哪里错了？

我们进行手动安装时的示例:

./netdata-installer.sh

  You are about to build and install netdata to your system.

  It will be installed at these locations:

   - the daemon     at /usr/sbin/netdata
   - config files   in /etc/netdata
   - web files      in /usr/share/netdata
   - plugins        in /usr/libexec/netdata
   - cache files    in /var/cache/netdata
   - db files       in /var/lib/netdata
   - log files      in /var/log/netdata
   - pid file       at /var/run/netdata.pid
   - logrotate file at /etc/logrotate.d/netdata

  This installer allows you to change the installation path.
  Press Control-C and run the same command with --help for help.

Press ENTER to build and install netdata to your system >   <--- in this point we need to ENTER

备注 - 在运行 netdata 时，我们只需输入“ENTER”，然后也许还有其他选项可以自动安装？

与其尝试构建一个可以读取文本和按下虚拟键的软件机器人，不如让程序以非交互方式安装:

cd /tmp/netdata && ./netdata-installer.sh --dont-wait
