Copying a list of files from one 'server' to another?

Sepia · #1 (**permalink**) 04-23-2007

I have two servers. I would like to copy some files from one directory on server A into the same directory on server B.

Its not all the files in in the directory, just some of them.

Is there a way to make a file list in a txt file and then somehow copy all the files in that list in one go to the other server?

Thanks.

files.txt contains a list of every file you want to copy.

Code:

for line in files.txt
do
    cp $line server:$line
done

You get the gist...

...oh - unless its scp or something and then you'd end up having to type in your password for each line

What shell are you using? If it's bash or ksh put the list of files in an array, e.g.:
Code:
filelist=( "file 1" "file 2" etc. )

scp "${filelist[@]}" remote.server:path
Or use the list directly on the command line:
Code:
scp "file 1" "file 2" etc. remote.server:path

In these situations you run the risk of exhausting the maximum length of arguments to a process. I ran into this problem today when I needed to randomly divide two massive sets of files evenly between two servers. Create a new directory for each server and fill it with symlinks to the files you wish to copy to that server. If it's a lot of files, automate it by creating a script:

Code:

cat file_list | sed 's/^.*$/ln -s & /' > symlink_script.sh

Execute the script inside of your new directory. Then, just copy that directory over to the target server, and scp will follow the symlinks.

For this copy, it will be easier for you to just do a ftp from the DOS command prompt

Code:

open DOS 
cd c:
ftp unixbox
user
paswword
cd /dir  [ directory where your tesh.sh is present]
get test.sh
bye

Make sure you're getting your syntax correct.

scp /file/location/of/test.sh 102.19.23.122@:/file/location/to/copy/to

And also - make sure you actually can reach 102.19.23.122
