Editor to share with you how to copy remotely, speed limit and breakpoint continuation under Linux. I hope you will get something after reading this article. Let's discuss it together.

Scp command-copy files remotely

Scp copies the local file filename to the / data/tmp directory of the remote machine 192.168.188.188 server

Scp-P 61204-l 40000 filename username@192.168.188.188:/data/tmp/

-P port Specifies the port to connect to on the remote host. Note that this option is written with a capital'Pants, because-p is already reserved for preserving the times and modes of the file in rcp (1).

#-P specify the port of the remote server ssh service, such as ssh port 61204

-l limit Limits the used bandwidth, specified in Kbit/s.

-l specifies that the speed limit of the copy is in ct/s. For example,-l 40000 indicates the speed of 40000Kbit/s=40000/8KB=5MB.

Note: scp does not support resuming from breakpoints.

Rsync + ssh breakpoint continuation

# rsync synchronizes the local file filename to the / data/tmp directory of the remote machine 192.168.188.188 server

Rsync-avzP-e'ssh-p 61204'-bwlimit=5000 filename username@10.20.90.101:/data/tmp/ > > scp_to_101.log

-a: operates in archive mode, copying directories and symbolic links, equivalent to-rlptgoD.

-v: detailed prompt

-z: compression

-P: yes, two parameters of-partial-progress are integrated.

-partial if the transfer is interrupted while copying files, the default action of rsync is to undo the pre-operation, that is, to delete some of the copied files from the target machine. If you want to continue the file on the next copy and do not need to re-copy all the files, you can use the-partial option to prevent rsync from deleting the copied parts if the transfer is interrupted.

-progress displays the progress bar

-e: the parameter allows users to freely choose the shell program they want to use to connect to the remote server

Ssh-p 61204

Specify the port of the ssh (other than the default 22) 61204

-bwlimit:-bwlimit=5000 limits bandwidth to 5000k Bytes/s = 5MB

Example above: use rsync to transfer local files filename to 192.168.188.188 / data/tmp directory using compressed archive transfer, speed limit 5MB, support breakpoint continuation using ssh protocol details can be found in man scp and man rsync manuals
