Ubuntu/Cent OS Find and SCP command

VicMP3 · 05-03-2013, 06:51 AM

Hello,

I'm trying to create a little script to backup some files from a remote linux server to another linux server using a intermediary vpn server.

x=`ssh msc@msc find /path/to/files -mtime +1 -name "filename*"`
scp msc@msc:$x /home/mx

Originally I though this would behave as gzip or other commands and wouldn't mind the newline in the find output.

But it seems it just starts to scp the 1st file and the rest it just outputs errors.

I was wondering if it's possible to change the way linux outputs when using find command . to be more precise can I remove the new line and turn it into space?

Thanks!

First thing is that you're using a wrong find command. Find should end with either -print or -exec option, like this:

Code:

~$ find /path/to/files -mtime +1 -name "filename*" -print

Second, the way you're saving find command output in x is wrong. You should do something like this:

Code:

#!/bin/bash
ssh msc@msc     ## You can use a password less login here using rsa keys
find /path/to/files -mtime +1 -name "filename*" -print > /tmp/list.txt
while read -r file; do
mv $file /home/mx/
done < /tmp/list.txt

this worx for me

Code:

[schneidz@hyper test]$ find . -type f 
./world
./hello
./l33t
[schneidz@hyper test]$ scp `find . -type f` schneidz@xbmc:test
world                                                                                              100%    0     0.0KB/s   00:00    
hello                                                                                              100%    0     0.0KB/s   00:00    
l33t                                                                                               100%    0     0.0KB/s   00:00    
[schneidz@hyper test]$ ssh schneidz@xbmc ls -l test
total 0
-rw-rw-r-- 1 schneidz schneidz 0 May  3 09:50 hello
-rw-rw-r-- 1 schneidz schneidz 0 May  3 09:50 l33t

Thanks for the help guys.

In the mean time i tried this and it worked with my SCP.

find /telos/msc/DATA -mtime +1 -name "CDR*" | xargs echo

ah in the end i did it with a while

my final script.

Code:

ssh msc@msc find /path/to/files -mtime +1 -name "CDR*" | while read fName; do scp msc@msc:${fName} /path/out/; done
x=`find /path/out/ -name "CDR*"`
gzip -f $x

Works fine this way. just though I'd share it if anyone needs anything similar.
