rz和sz是Linux/Unix同Windows进行Zmodem文件传输的命令工具,都使用Zmodem文件传输协议。
- rz: receive zmodem的缩写，运行该命令会弹出一个文件选择窗口，从本地选择文件上传到Linux服务器。
- sz: send zmodem的缩写，将选定的文件发送（send）到本地服务器，即从Linux下载到Windows系统；
验证sz、rz软件包是否已经安装：
rpm -qa | grep lrzsz
yum install -y lrzsz
sz命令
sz命令是利用ZModem协议来从Linux服务器传送文件到本地，一次可以传送一个或多个文件。
常用参数：
-a ： 以文本方式传输（ascii）。-b ： 以二进制方式传输（binary）。-e ： 对控制字符转义（escape），这可以保证文件传输正确。[keepmoving@192 test]$ sz --helpsz version 0.12.20Usage: sz [options] file ... or: sz [options] -{c|i} COMMANDSend file(s) with ZMODEM/YMODEM/XMODEM protocol (X) = option applies to XMODEM only (Y) = option applies to YMODEM only (Z) = option applies to ZMODEM only -+, --append append to existing destination file (Z) -2, --twostop use 2 stop bits -4, --try-4k go up to 4K blocksize --start-4k start with 4K blocksize (doesn't try 8) -8, --try-8k go up to 8K blocksize --start-8k start with 8K blocksize -a, --ascii ASCII transfer (change CR/LF to LF) -b, --binary binary transfer -B, --bufsize N buffer N bytes (N==auto: buffer whole file) -c, --command COMMAND execute remote command COMMAND (Z) -C, --command-tries N try N times to execute a command (Z) -d, --dot-to-slash change '.' to '/' in pathnames (Y/Z) --delay-startup N sleep N seconds before doing anything -e, --escape escape all control characters (Z) -E, --rename force receiver to rename files it already has -f, --full-path send full pathname (Y/Z) -i, --immediate-command CMD send remote CMD, return immediately (Z) -h, --help print this usage message -k, --1k send 1024 byte packets (X) -L, --packetlen N limit subpacket length to N bytes (Z) -l, --framelen N limit frame length to N bytes (l>=L) (Z) -m, --min-bps N stop transmission if BPS below N -M, --min-bps-time N for at least N seconds (default: 120) -n, --newer send file if source newer (Z) -N, --newer-or-longer send file if source newer or longer (Z) -o, --16-bit-crc use 16 bit CRC instead of 32 bit CRC (Z) -O, --disable-timeouts disable timeout code, wait forever -p, --protect protect existing destination file (Z) -r, --resume resume interrupted file transfer (Z) -R, --restricted restricted, more secure mode -q, --quiet quiet (no progress reports) -s, --stop-at {HH:MM|+N} stop transmission at HH:MM or in N seconds --tcp build a TCP connection to transmit files --tcp-server open socket, wait for connection -u, --unlink unlink file after transmission -U, --unrestrict turn off restricted mode (if allowed to) -v, --verbose be verbose, provide debugging information -w, --windowsize N Window is N bytes (Z) -X, --xmodem use XMODEM protocol -y, --overwrite overwrite existing files -Y, --overwrite-or-skip overwrite existing files, else skip --ymodem use YMODEM protocol -Z, --zmodem use ZMODEM protocolshort options use the same arguments as the long ones常用命令：
- 如果能够确定所传输的文件是文本格式的，使用 sz -a files
- 如果是二进制文件，使用 sz -be files
将123.xlsx文件下载到windows系统中（默认位置在桌面上）：
sz -y 123.xlsx 
sz -a 123.xlsx
rz命令
rz：运行该命令会弹出一个文件选择窗口，从本地选择文件上传到Linux服务器。使用rz -y 命令时会弹出选择文件对话框
常用参数：
-b ： 以二进制方式，默认为文本方式。（Binary (tell it like it is) file transfer override.）-e ： 对所有控制字符转义。（Force sender to escape all control characters; normally XON, XOFF, DLE, CR-@-CR, and Ctrl-X are escaped.）[keepmoving@192 test]$ rz --helprz version 0.12.20Usage: rz [options] [filename.if.xmodem]Receive files with ZMODEM/YMODEM/XMODEM protocol (X) = option applies to XMODEM only (Y) = option applies to YMODEM only (Z) = option applies to ZMODEM only -+, --append append to existing files -a, --ascii ASCII transfer (change CR/LF to LF) -b, --binary binary transfer -B, --bufsize N buffer N bytes (N==auto: buffer whole file) -c, --with-crc Use 16 bit CRC (X) -C, --allow-remote-commands allow execution of remote commands (Z) -D, --null write all received data to /dev/null --delay-startup N sleep N seconds before doing anything -e, --escape Escape control characters (Z) -E, --rename rename any files already existing --errors N generate CRC error every N bytes (debugging) -h, --help Help, print this usage message -m, --min-bps N stop transmission if BPS below N -M, --min-bps-time N for at least N seconds (default: 120) -O, --disable-timeouts disable timeout code, wait forever for data --o-sync open output file(s) in synchronous write mode -p, --protect protect existing files -q, --quiet quiet, no progress reports -r, --resume try to resume interrupted file transfer (Z) -R, --restricted restricted, more secure mode -s, --stop-at {HH:MM|+N} stop transmission at HH:MM or in N seconds -S, --timesync request remote time (twice: set local time) --syslog[=off] turn syslog on or off, if possible -t, --timeout N set timeout to N tenths of a second -u, --keep-uppercase keep upper case filenames -U, --unrestrict disable restricted mode (if allowed to) -v, --verbose be verbose, provide debugging information -w, --windowsize N Window is N bytes (Z) -X --xmodem use XMODEM protocol -y, --overwrite Yes, clobber existing file if any --ymodem use YMODEM protocol -Z, --zmodem use ZMODEM protocolshort options use the same arguments as the long ones上传文件到服务器：
