linux 制作一个ftp菜单

制作一个FTP菜单可以通过创建一个bash脚本来实现。以下是一个基本的FTP菜单的示例：

#!/bin/bash
echo "Welcome to FTP Menu"
PS3='Please enter your choice: '
options=("Connect to FTP Server" "List remote directory" "Change remote directory" "Upload file to remote directory" "Download file from remote directory" "Quit")
select opt in "${options[@]}"
do
    case $opt in
        "Connect to FTP Server")
            echo "Enter FTP server address:"
            read server
            echo "Enter username:"
            read username
            echo "Enter password:"
            read -s password
            ftp -n $server <<END_SCRIPT
            quote USER $username
            quote PASS $password
            END_SCRIPT
            break
            ;;
        "List remote directory")
            echo "Enter remote directory path:"
            read path
            ftp -n $server <<END_SCRIPT
            quote USER $username
            quote PASS $password
            cd $path
            ls
            END_SCRIPT
            break
            ;;
        "Change remote directory")
            echo "Enter remote directory path:"
            read path
            ftp -n $server <<END_SCRIPT
            quote USER $username
            quote PASS $password
            cd $path
            END_SCRIPT
            break
            ;;
        "Upload file to remote directory")
            echo "Enter local file path:"
            read localpath
            echo "Enter remote directory path:"
            read remotepath
            ftp -n $server <<END_SCRIPT
            quote USER $username
            quote PASS $password
            cd $remotepath
            put $localpath
            END_SCRIPT
            break
            ;;
        "Download file from remote directory")
            echo "Enter remote file path:"
            read remotepath
            echo "Enter local directory path:"
            read localpath
            ftp -n $server <<END_SCRIPT
            quote USER $username
            quote PASS $password
            cd $(dirname $remotepath)
            get $(basename $remotepath) $localpath
            END_SCRIPT
            break
            ;;
        "Quit")
            break
            ;;
        *) echo "Invalid option $REPLY";;
    esac
done

该脚本提供了以下操作：

1. 连接到FTP服务器
2. 列出远程目录
3. 更改远程目录
4. 将文件上传到远程目录
5. 从远程目录下载文件
6. 退出

要使用该脚本，请将其保存为一个文件（例如`ftp_menu.sh`），然后在终端中运行以下命令以使其可执行：

chmod +x ftp_menu.sh

然后，可以通过运行以下命令来启动FTP菜单：

./ftp_menu.sh
