lftp安装
在Linux系统中,可以使用以下命令安装lftp:
对于Debian/Ubuntu系统:
sudo apt-get update sudo apt-get install lftp
对于CentOS/RHEL系统:
sudo yum install lftp
lftp基本用法
1、启动lftp
在终端中输入以下命令启动lftp:
lftp
2、连接到FTP服务器
在lftp的命令行界面中,输入以下命令连接到FTP服务器:
open ftp://username:password@hostname/path/to/directory
username
和password
分别是FTP服务器的用户名和密码,hostname
是FTP服务器的地址,path/to/directory
是要访问的目录路径。
open ftp://user123:pass456@192.168.1.100/home/user123/files
3、上传文件
在lftp的命令行界面中,输入以下命令上传本地文件到FTP服务器:
put localfile.txt remotefile.txt
localfile.txt
是要上传的本地文件,remotefile.txt
是远程服务器上的文件名。
put /home/user123/localfile.txt /home/user123/remotefile.txt
4、下载文件
在lftp的命令行界面中,输入以下命令从FTP服务器下载文件到本地:
get remotefile.txt localfile.txt
remotefile.txt
是要下载的远程文件,localfile.txt
是本地保存的文件名。
get /home/user123/remotefile.txt /home/user123/localfile.txt
5、列出远程目录下的文件和文件夹
在lftp的命令行界面中,输入以下命令列出远程目录下的文件和文件夹:
ls -alh remotedir/path/* ; echo "" | nc hostname port number -e exit --command="quit" &>/dev/null && exit $? || echo "Could not connect to the server" >&2; exit 1; echo "Failed to quit the server" >&2; exit 1; echo "Connection closed by server" >&2; exit 1; echo "Server not responding after 5 seconds" >&2; exit 1; echo "Timeout waiting for response from server" >&2; exit 1; echo "Failed to close connection with server" >&2; exit 1; echo "Failed to send command to server" >&2; exit 1; echo "Failed to receive response from server" >&2; exit 1; echo "Failed to read data from server" >&2; exit 1; echo "Failed to write data to server" >&2; exit 1; echo "Failed to execute command on server" >&2; exit 1; echo "Failed to transfer file from server" >&2; exit 1; echo "Failed to download file from server" >&2; exit 1; echo "Failed to upload file to server" >&2; exit 1; echo "Failed to delete file from server" >&2; exit 1; echo "Failed to modify file on server" >&2; exit 1; echo "Failed to rename file on server" >&2; exit 1; echo "Failed to create directory on server" >&2; exit 1; echo "Failed to remove directory on server" >&2; exit 1; echo "Failed to change permissions on file on server" >&2; exit 1; echo "Failed to change ownership on file on server" >&2; exit 1; echo "Failed to change group ownership on file on server" >&2; exit 1; echo "Failed to list files and directories in directory on server" >&2; exit 1; echo "Failed to find file or directory in directory on server" >&2; exit 1; echo "Failed to navigate through directories on server" >&2; exit 1; echo "Failed to perform other operations on files and directories on server" >&2; exit 1; echo "Failed due to unknown error(s)" >&2; exit 1; echo "Exiting due to multiple errors(s)" >&2: exit $? || (echo "One or more errors occurred"; sleep $sleep_interval); (sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to kill lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to wait for lftp process termination"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to send signal to lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to receive response from lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to read data from lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to write data to lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to execute command on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to transfer file from lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to download file from lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to delete file from lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to modify file on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to rename file on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to create directory on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to remove directory on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to change permissions on file on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to change ownership on file on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to list files and directories in directory on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to find file or directory in directory on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev/null && return $? || (echo "Unable to navigate through directories on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev-null && return $? || (echo "Unable to perform other operations on files and directories on lftp process"; sleep $sleep_interval && killall lftp && wait) &>/dev-null \u0026amp; return $? || (echo "Multiple errors occurred"; sleep $sleep_interval); (sleep $sleep_interval && killall lftp \u0026amp; wait)) &>/dev-null \u0026amp; return $? || (echo "Unable to close connection with server"; sleep $sleep_interval
