SecureCRT upload, download and common commands

the file transfer protocols under SECURECR are ASCII, Xmodem, Ymodem, Zmodem
 
 
 
ASCII: This is the fastest transport protocol, but only text files can be transferred.
 
 
 
Xmodem: This ancient transmission protocol is slow, but due to the use of CRC error detection method, the transmission accuracy rate can be as high as 99.6%.
 
 
 
Ymodem: This is an improved version of Xmodem, which uses 1024-bit segments to deliver faster than Xmodem.
 
 
 
Zmodem:zmodem adopts the stream-flow (streaming) transmission mode, the transmission speed is fast, but also has the function of automatically changing the section size and the breakpoint continuation transmission, the fast error detection and so on. This is currently the most popular file Transfer Protocol

options->session Options->terminal->xmodem/zmodem
 
set upload and download directories on the right
 
 
 
using Zmodem to upload files from a client to a Linux server
 
1. Log in to the Linux terminal with SECURECRT.
 
2. Select the path where you want to place the uploaded file, in the directory and then enter the RZ command, SECURECRT will pop up the file selection dialog box, find the file you want to upload in the search scope, press the Add button. Then OK can upload the file to Linux.
 
or, in the Transfer->zmodem upoad list pop-up File selection dialog box, select the file and press the Add button. Then the OK window closes automatically. Then under Linux, select the directory where the files are stored and enter the RZ command. Liunx the file to the directory.
 
to download files to the client using Zmodem:
 
sz filename
 
Zmodem receive can start on its own. The downloaded file is stored in the default download directory you set.
 
 
 
if the RZ, sz command is not valid, please install rzsz-0.12.20-853.2.i586.rpm first
 
the specific installation method is:
 

RPM-IVH rzsz-0.12.20-853.2.i586.rpm

Common commands:
First, LS only lists the file name (equivalent to Dir,dir can also be used)
-A: Lists all files, including hidden files.
-L: List form, which contains most of the properties of the file.
-R: Recursive display.
--help: Help for this command.
Second, CD change directory
CD/: Go to the root directory
CD: Go back to your directory (different directories are different, root is/root,xxt for/home/xxt
Cd.. : Back to Parent directory
PWD: Displays the directory where you are currently
Three. Less file name: View the contents of the file.
Four. Q exit the Open file.
Five. Upload file: RZ Select the file to be transferred, OK.
Six. download file: Sz Specify the file name, enter to hit, that is downloaded to the Securecrt/download directory.
Seven: Delete file: RM Delete file, rmdir delete empty directory.

Eight. Show the last 20 commands entered: History 20

Nine. Get help command--help View command under detailed parameters: such as: RZ--help, Sz--help.


10. The CD Entry command to a folder:
mkdir+ folder name command to create a folder
sz+ file name from server-side send files to native command
RZ commands to transfer files from the local to the server side
ll lists all files in the current directory, including details for each file
Dir to the current folder
VI Open the current file
11. When editing a file:
A switch to edit mode
CTRL + C Exit Edit mode
DD Delete entire row
: Q Exits the current file
: W writes and saves the current file
-F Force XX parameters ...

Other commands:
1.PS-EF//View the server process as a list of the server processes that are displayed.
PS shows the process currently running on the system/usr/bin/ps [options]-e display each now running process-F to generate a full list

4. I am generally accustomed to using the PS–EF command to see the server process as a list, and to see the process of the server with the command Pstree so that the server process is displayed as a tree.
The advantage of the Pstree command is that the parent process of a process can be identified immediately. You may need to use the-P option to display the PID for each process, and the-u option to display the user name that started the process.
In general, this tree structure is longer, and you need to do so Pstree–up | Less this will give you an overview of the entire process tree structure.
