产卵命令未找到

问题描述

我有一个错误尝试运行sh文件

I have an error trying to run a .sh file

line 2: spawn: command not found
": no such file or directory
bash.sh: line 3: expect: command not found
bash.sh: line 4: send: command not found

#!/usr/bin/expect -f
spawn sftp -o IdentityFile=MyFile.ppk [email protected]
expect "XXX.XXX.XXX.XXX.gatewayEnter passphrase for key 'MyFile.ppk.ppk':"
send "myPassword"

任何想法，为什么会发生？

Any idea why it happens?

推荐答案

它的工作原理OK，我（从错误SFTP： SSH：无法解析主机名XXX.XXX.XXX.XXX：姓名或服务不知道），尽​​管 .SH 扩展的的（的）脚本是有点倒胃口; - ）

It works OK for me (error from sftp: ssh: Could not resolve hostname XXX.XXX.XXX.XXX: Name or service not known), though the .sh extension for an expect (tcl) script is a little off-putting ;-)

通常，当这种莫名/ UN predictable行为发生，这是因为剧本是根据的（记事本），它使用 \\ r \\ n 划线。这起严重破坏 /的脚本，因为只有 \\ n 有望作为行分隔符。

Often when this sort of unexplainable/unpredictable behavior happens, it is because the script was edited under windows (notepad.exe), which uses \r\n to delimit lines. This plays havoc with unix/linux scripts, as only \n is expected as a line delimiter.

您可以使用以这两种格式之间进行转换。作为一个实验，我转换你的脚本为DOS格式，果然得到了类似的错误：

You can use the dos2unix and unix2dos utilities to convert between the two formats. As an experiment, I converted your script to "dos" format, and sure enough got a similar error:

ubuntu@ubuntu:~$ unix2dos bash.sh
unix2dos: converting file bash.sh to DOS format ...
ubuntu@ubuntu:~$ ./bash.sh
": no such file or directory
ubuntu@ubuntu:~$ dos2unix bash.sh
dos2unix: converting file bash.sh to Unix format ...
ubuntu@ubuntu:~$ ./bash.sh
spawn sftp -o IdentityFile=MyFile.ppk [email protected]
ssh: Could not resolve hostname XXX.XXX.XXX.XXX: Name or service not known
Couldn't read packet: Connection reset by peer
send: spawn id exp6 not open
    while executing
"send "myPassword""
    (file "./bash.sh" line 4)
ubuntu@ubuntu:~$
