shell批量下载/上传ftp文件

本shell基于ftp客户端，在终端运行ftp -h 后，结果如下

Usage: { ftp | pftp } [-46pinegvtd] [hostname]
           -4: use IPv4 addresses only
           -6: use IPv6, nothing else
           -p: enable passive mode (default for pftp)
           -i: turn off prompting during mget
           -n: inhibit auto-login
           -e: disable readline support, if present
           -g: disable filename globbing
           -v: verbose mode
           -t: enable packet tracing [nonfunctional]
           -d: enable debugging

测试环境：deepin 20.8

源码

​​ftp.sh​​

可以实现从本地向服务器，或从服务器到本地批量传输文件

#!/bin/bash

shell_name=$0
cmd=$1
read username password server port < <(echo $2|awk -F '[@:]' '{print $1,$2,$3,$4}')
port=${port:-"21"}
src_dir=$3
dst_dir=$4

usage(){
        cat >&1 <<-EOF
        Usage: ${shell_name} <cmd> <username:password@server>[:port] <src> <dist>
        cmd:
            get                from ftp server get download file.
            put                from local put file to ftp server.
        src:
            src                if cmd is get,it is ftp server,otherwise local server.
        dst:
            dst                if cmd is get,it is local server,otherwise ftp server.
        EOF
}

get(){
        ftp -n -v <<-EOF
        open $server $port
        user $username $password
        binary
        cd $src_dir
        lcd $dst_dir
        prompt
        mget *
        bye
        EOF
}

put(){
        ftp -n -v <<-EOF
        open $server $port
        user $username $password
        binary
        cd $dst_dir
        lcd $src_dir
        prompt
        mput *
        bye
        EOF
}

if [[ $# < 3 || $# > 4 ]];then
        echo "wrong number of parameters."
        usage
        exit
fi

case $cmd in
        "get")
                get
                ;;
        "put")
                put
                ;;
        *)
                usage
                ;;
esac

用法

直接运行，结果如下

wrong number of parameters.
        Usage: ./ftp.sh <cmd> <username:password@server>[:port] <src> <dist>
cmd:
    get                from ftp server get download file.
    put                from local put file to ftp server.
src:
    src                if cmd is get,it is ftp server,otherwise local server.
dst:
    dst                if cmd is get,it is local server,otherwise ftp server.

若未提供端口号，则默认端口号为２１

１，从远程ftp服务器批量下载文件

比如假设，ftp服务器的ip为192.168.1.103，端口号为2221，用户名和密码均为admin，现在欲从服务器的/Download目录下载所有文件到本地/tmp目录下

./ftp.sh get admin:admin@192.168.1.103:2221 /Download /tmp

２，从本地主机批量上传文件到ftp服务器

上传本地目录当下所有文件到服务器

./ftp.sh put admin:admin@192.168.1.103:2221 . /Download
