FTP脚本问题

Question

我们使用 FTP 脚本将文件发送到服务器，之前我们曾经在 AIX 上运行脚本，但现在由于云迁移，我们的脚本失败了，因为它在 SLES 12 中使用了 LFTP。

我需要修改脚本的帮助。

就像它无法将文件发送到目标服务器并且 ksh 已经安装在我们的服务器上。

代码 ：

#!/bin/bash


#alias ftp=/usr/bin/lftp
alias ftp=/usr/bin/lftp

#Current Execution specific variables
PID=$$
TIMESTAMP=`date '+%Y%d%m%H%M%S'`

#Validate TIMESTAMP and PID
if [[ -z ${TIMESTAMP} || -z ${PID} ]]
then
        echo "ERROR: Failed to get process id and/or system timestamp"
        exit 1
fi

#Sub-routine to display command line usage
usage()
{
        echo "$1"
        echo "Please find below the valid argument options "
        echo "-h Host Name"
        echo "-s Source Dir"
        echo "-d Destination Dir"
        echo "-f Feed Name"
        echo "-o Output Feed Name"
        echo "-l Log File"
        echo "-u User Id"
        echo "-p Password"
        exit 1
}

#Sub-routine to check FTP errors
sub_check_error(){
        ftp_code=$1
        log_code=`egrep -i "fail|error" ${LOG_FILE}.ftp |wc -l| awk '{print $1}'`
        status=0
        ((status=ftp_code+log_code))

        if [ $status == 0 ]
        then
                echo "INFO: FTP $2 script succeeded..."
        else
                echo "ERROR: FTP $2 script failed"
                exit 1
        fi
}

输出错误日志：

当我运行脚本时，这是我得到的输出。

Answer 1

这是一个 reference 的帖子，我在其中引用了几篇我已经解决了这个问题的帖子。

有更好、更简单、更可靠的替代品。如果您有任何选择（您通常会这样做），请避免将ftp 用于脚本。它不是为此而设计的。

当你在这里的时候，搜索lftp和sftp，但是真的考虑使用 scp 或什至 ssh to run some list of commands remotely 来做您需要的事情。

只需检查您的返回代码。
