我刚刚写了一个非常简单的预期脚本来包装rsync,但它似乎给我带来了麻烦。基本上,我正在自动执行从rsync调用的ssh登录提示。我还必须通过rsync将参数传递给ssh,这样它就不会进行主机密钥检查。我很清楚ssh身份验证密钥和ssh keygen,但是我有很好的理由这样做,所以没有关于在命令行上传递密码的讲座。

脚本

#!/usr/local/bin/expect -f

if {$argc != 5} {
  puts "usage: remoteCopy {remotehost, username, password, localfile, remoteloc}"
  exit 1
}

set remotehost [lindex $argv 0]
set username [lindex $argv 1]
set password [lindex $argv 2]
set localfile [lindex $argv 3]
set remoteloc [lindex $argv 4]

set timeout -1

spawn rsync -e \"ssh -q -o StrictHostKeyChecking=no\" $localfile $username@$remotehost:$remoteloc
expect "Password"; send "$password\r"

以下是脚本的完整输出:

产量

avoelker@localhost  $ ./remoteFileCopy.tcl remotehost remoteuser remotepass ~/localfile /tmp/
spawn rsync -e "ssh -q -o StrictHostKeyChecking=no" /localhost/home/avoelker/localfile remoteuser@remotehost:/tmp/
rsync: Failed to exec "ssh: No such file or directory (2)
rsync error: error in IPC code (code 14) at pipe.c(83)
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(434)
send: spawn id exp6 not open
    while executing
"send "$password\r""
    (file "./remoteFileCopy.tcl" line 17)
avoelker@localhost  $

我觉得rsync正在尝试执行 "ssh 而不仅仅是 ssh 但是,从expect的stdout复制和粘贴输出的第一行( rsync -e "ssh -q -o StrictHostKeyChecking=no" /localhost/home/avoelker/localfile remoteuser@remotehost:/tmp/ )直接进入shell非常好,所以我知道rsync没有问题。

当我将-e参数从 spawn rsync 行中,预期脚本执行时没有错误,但我必须向脚本添加主机键检查,我不想这样做。

有没有比Expect/TCL更有经验的人知道我做错了什么?
