Linux -- use SecureCRT to upload and download files, and linux -- securecrt

The file transfer protocols in SecureCRT include ASCII, Xmodem, Ymodem, and Zmodem.

ASCII: This is the fastest transmission protocol, but it can only transmit text files.
Xmodem: this old transmission protocol is slow, but the CRC error detection method can achieve a Transmission Accuracy of up to 99.6%.
Ymodem: This is an improved version of Xmodem. It uses a 1024-bit segment for transmission, which is faster than Xmodem.
Zmodem: Zmodem uses streaming Transmission Mode to achieve fast transmission speed. It also provides functions such as automatic change of segment size, resumable data transfer, and fast error detection. This is currently the most popular file transfer protocol.

1. Install lrzsz on the server before using SecureCRT for upload and download:
Yum-y install lrzsz ")

In rz, "r" indicates received ed (received). When "rz" is input, it indicates that the server receives the file, and the file is uploaded locally to the server.
In sz, "s" indicates "send". When "sz" is input, it indicates that the server wants to send the file, that is, to send the file from the server to the local device, or to download the file locally from the server.
Note: Both send and received actions are initiated on the server.

Download an object: sz filename
Download multiple files: sz filename1 filename2
Download all files in the dir directory, excluding the folder: sz dir /*

1. Enter sz filename1 filename2 filename3 and press enter, as shown below

2. Select the storage path and click "OK". The page is shown as follows:

3. Click "Open folder" to view the two files downloaded to the local device:

3. Set the default directory for uploading and downloading files
