SCP the latest file from the remote host

spkandy · #1 (**permalink**) 08-07-09, 04:22

Hi All,
Greetings for the day..

I just want to secure copy a latest data file from the remote host.
Is there any option available in 'SCP'?
I am using ssh key-authentication, so SCP/SSH is the only option.
Please help me..

Cheers,

Kandy

I would use "ssh" and "find" to find the latest file, get the name from it and then apply this to "scp" to get the file.

If you want to use this mechanism to update a local copy, would "rsync" be an option for you?

Try somethng like this:

Code:

ssh remote1 "ls -tr /my/file/dir|tail -1"|xargs -i+ scp remote1:/my/file/dir/+ .

Hi LKBrwn_DBA,
I tried the below code, but it throws the syntax error.
Can you please corect me..

ssh <UID>@<HOSTNAME> "ls -tr /Parent/child/myfile*|xargs -i+ scp <UID>@<HOSTNAME>:/Parent/child/+ /MyDirectory/

Thanks,
Kandy

You seem to be missing the "tail -1" from the previous example.

It would help if you actually gave us the error message.

You are missing the 'tail -1' and closing double quote:

Code:

ssh <UID>@<HOSTNAME> "ls -tr /Parent/child/myfile*|tail -1"|xargs -i+ scp <UID>@<HOSTNAME>:/Parent/child/+ /MyDirectory/
