This article mainly explains "introduction to the use of rz and sz commands on linux". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the introduction to the use of rz and sz commands on linux.

Two commands related to ssh provide convenient operation:

Sz: sends (send) the selected files to the local machine

Rz: running this command will bring up a file selection window and upload the file from the local selection to the server (receive)

Rz,sz is a command line tool for ZModem file transfer between Linux/Unix and Windows.

The windows side needs a telnet/ssh client that supports ZModem (such as SecureCRT)

Run the command rz, that is, to receive the file, SecureCRT will pop up the file selection dialog box, close the dialog box after selecting the file, and the file will be uploaded to the current directory

Note: using rz alone will have two problems: upload interruption, upload file changes (md5 is different), the solution is to upload using rz-be, and uncheck the box before "Upload files as ASCII" in the pop-up dialog.

-b binary uploads and downloads in the way of binary and does not interpret the character as ascii

-e forces all escape control characters, such as Ctrl+x,DEL, etc.

To run the command sz file1 file2 is to send files to windows (the saved directory is configurable), which is much more convenient than the ftp command, and the server no longer has to open the FTP service.

The two gadgets rz/sz on PS:Linux can be installed with lrzsz-x.x.xx.rpm.

Of course, you can also set up the directory:

Set the default directory for uploads and downloads in SecureCRT

You can set directories for uploading and downloading under options- > session options- > file transfer

The rest of you just need to log in to the linux terminal with SecureCRT:

Send file to client: sz filename

Zmodem reception can be started on its own.

Upload files from the client to the linux server:

As long as the server executes: rz

Then select the file in SecureCRT to send, protocol zmodem

Introduction of rz/sz (lrz/lsz), a file transfer tool between Linux and Windows

[what is rz/sz (lsz/lrz)]

To put it simply, you can easily use these two sz/rz tools to achieve file transfer (send and receive) between Linux and Windows at a speed of about 10KB/s, suitable for small and medium-sized files. Rz/sz transmits data over the Zmodem protocol.

[why use rz/sz]

The methods of file sharing between ordinary Linux and Windows mainly include the establishment of nfs to achieve file sharing, and tftp and other methods, but they are very troublesome, but if they are only small files (tens of K, hundreds of K), then it is extremely convenient to use rz/sz directly. If you have a large file, you still have to consider other sharing methods mentioned above. After all, the rz/sz speed is only about 10K, so it will be exhausting to send large files.

[how to use]

(1) under Windows, connect the Com port to the development board with SecureCRT (or the hyperterminal that comes with Windows), or connect to the Linux server with protocols such as ssh.

(2) on the Linux side, after installing the rz/sz (lrz/lsz) tool (in embedded development, most of the compiled rz/sz tools have been put into rootfs, ordinary Linux systems, if not, you can download the source code and install it yourself), you can run rz/sz directly to realize the file transfer between Linux and Windows:

A. Copy / download files from windows to Linux (development board):

After running rz, the file selection dialog box under WIndows automatically pops up. After selecting the corresponding file, add it, and then confirm, start the transfer, and copy the files in windows to Linux.

B. Copy the files in Linux to a folder in Windows:

Execute sz file_name to copy the file file_name under the current folder of Linux to the corresponding directory of Windows, where the Windows directory is set by the tool you are currently running.

Here I am using SecureCRT, the specific method to change the default path of rz upload / sz download:

Right-click the current session session-> Session Options-> Terminal-> Xmodem/Zmodem-> Directories:

Upload: the path you want to set

Download: the path you want to set

The following is a supplement:

[commonly used in SecureCRT ssh]

Yum install lrzsz-y

Note: rz sz can be used directly after rhel installs the system.

Method 2: source file compilation method

Installation configuration for centos x.x version lrzsz

The code is as follows:

Mkdir-p / usr/src/tools

Cd / home/ryan/tools

Wget http://down1.chinaunix.net/distfiles/lrzsz-0.12.20.tar.gz

Tar zxvf lrzsz-0.12.20.tar.gz

Cd lrzsz-0.12.20

. / configure-- prefix=/usr/local/lrzsz

Make

Make install

Cd / usr/bin

Ln-s / usr/local/lrzsz/bin/lrz rz

Ln-s / usr/local/lrzsz/bin/lsz sz

Rz

Method 3:rpm installation:

Rpm ivh lrzsz-x.rpm (look in the CD)

Skip it here.

Example: a student encounters the problem of uploading and downloading rz,sz

Rz is normal and sz cannot download the file locally. But the students are still confused and don't know why.

Problem and solution process:
