SCP Command Combat Style

1.Summary

SCP: Copy a File Between Two Systems

2.Usage

scp [OPTION] [user@]SRC_HOST:]file1 [user@]DEST_HOST:]file2

Notice:

In SCP command,

-P - Specifies the remote host ssh port.

-p - Preserves files modification and access times.

In SSH command,

-p - Specifies the remote host ssh port.

3.Combat case

You know there are less than one more program running in remote cloud/VM. E.g:

there is a program b.py, that is dependent on another program a.py, if

this case occurs, we should push that two program into remote cloud/VM to run.

Now, that's time to use scp(secure copy). package them and copy, copy that

into my VM's folder macos_share via:(From Host to Guest VM)

scp -P target_port ~/{a,b}.py [email protected]:~/macos_share

and if into my remote Cloud's folder macos_share_cloud, then via:

(From remote cloud or other host to guest VM)

scp -P target_port ~/{a,b}.py [email protected]:~/macos_share_cloud

then run that transmitted copied file, that means product a instruct to active

a.py via ssh command with " and "(From Host to Guest VM):

ssh -p target_port [email protected] "python3 ~/macos_share/a.py"

and if run in remote cloud, then via(From remote cloud/other host to guest VM):

ssh -p target_port [email protected] "python3 ~/macos_share/a.py" 

Finally, if want to copy the result to the local machine, then use scp, again:

(From Host yo Guest VM)

scp -P target_port [email protected]:~/macos_share/a.py ~/Desktop/ 

and if from cloud to local, then(From cloud or other host to guest VM):

scp -P target_port [email protected]:~/macos_share_cloud/a.py ~/Desktop/
