我的期望脚本在r同步VirtualBox目录时无法继续。
这是脚本：
#!/usr/bin/expect -f
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Documents/ username@server:/home/username/BAK/Documents/
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/AndroidDev/ username@server:/home/username/BAK/AndroidDev/
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Android/ username@server:/home/username/BAK/Android/
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Videos/ username@server:/home/username/BAK/Videos/ ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/VirtualBox\ VMs/ username@server:/home/username/BAK/"VirtualBox\ VMs/" ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Pictures/ username@server:/home/username/BAK/Pictures ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn scp -v /home/james/.vimrc username@server:/home/username/BAK/ ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn scp -v /home/james/.bashrc username@server:/home/username/BAK/ ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn scp -v /home/james/.profile username@server:/home/username/BAK/ ;
expect "password:"
send "thepassword\r"
interact
sleep 1
spawn scp -v /home/james/.xsession* username@server:/home/username/BAK/ ;
expect "password:"
send "thepassword\r"
interact
sleep 1
如果我将spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/rschostag/VirtualBox\ VMs/ remote@server:/home/directory/BAK/VirtualBox更改为spawn scp -vr /home/rschostag/VirtualBox\ VMs/ remote@server:/home/directory/BAK/VirtualBox，则可行。但是，我不想每次都进行完整备份。
逐步备份此目录或以其他方式使rsync命令正常工作的最佳方法是什么？
谢谢！
根据要求，请查看expect -d script的输出如下：
$ sudo expect -d rsync_backup
expect version 5.45
argv[0] = expect argv[1] = -d argv[2] = rsync_backup
set argc 0
set argv0 "rsync_backup"
set argv ""
executing commands from command file rsync_backup

这是它挂起的地方，并没有提供我可以识别的错误消息。
我移动了远程VirtualBox目录并再次启动备份，并在运行备份几天后最终完成。备份的总大小为71 GB。我用expect -d运行它，它在终端中输出了一个非常详细的输出，所以这单独是有用的，因为没有-d的脚本可能看起来像是挂起只是因为它没有在输出中打印任何内容。所以，我相信，除了没有任何进展指示之外，从来没有任何错误，这让我相信它可能不起作用。
感谢您就expect -d选项向我提供建议。
