获取退出状态code从“FTP”命令在Linux的shell [英] Getting exit status code from 'ftp' command in linux shell

问题描述

我需要从一个命令行程序retrive退出状态code。不用担心，我用$？
但对于FTP，即使不连接，它打开ftp的外壳，所以我不能够理解的连接都不会发生。

I need to retrive the exit status code from a command line program. No worries, I used $?. But for ftp, even if it doesn't connect, it opens the ftp shell, so I'm not able to understand that the connection haven't take place.

试试这个code表示理解：

Try this code for understand:

#!/bin/sh

ftp 1234567
OUT=$?
if [ $OUT -eq 0 ];then
   echo "ftp OK"
else
   echo "ftp Error: "$OUT
fi

exit 0

任何帮助吗？

推荐答案

您应该寻找从ftp命令，而不是寻找一个状态成功消息。这是226传输完成。您可以与您的系统上FTP的手动确认。

You should be looking for success message from ftp command rather than looking for a status. It's "226 Transfer complete". You can confirm it with ftp manual on your system.

200 PORT command successful.
150 Opening ASCII mode data connection for filename.
226 Transfer complete.
189 bytes sent in 0.145 seconds (0.8078 Kbytes/s)

下面是一个示例脚本。

FTPLOG=/temp/ftplogfile
ftp -inv <<! > $FTPLOG
open server
user ftp pwd
put filename
close
quit
!

FTP_SUCCESS_MSG="226 Transfer complete"
if fgrep "$FTP_SUCCESS_MSG" $FTPLOG ;then
   echo "ftp OK"
else
   echo "ftp Error: "$OUT
fi
exit 0
