using rsync

Shell Programming and Scripting
1

I'm just trying to use rsync to retreive the file from different servers with script. i want to look for a file, if the file exists, then retreive the file from different servers, and put it in one file. I have the following command.

 rsync -v -e ssh jerry@openbsd.nixcraft.in:~/webroot.txt /tmp

any idea how to write the script. Thanks

If you've got SSH, and want to receive only one file from a fixed location:

scp <user>@<host>:webroot.txt /tmp/.

An example would be:

for i in srv1 srv2 srv3
do
    scp <user>@${i}:webroot.txt /tmp/.
    cat /tmp/webroot.txt >> /tmp/webroot_all.txt
done
3 
for i in srv1 srv2 srv3
do
    ssh <user>@${i} 'cat /path../webroot.txt 2>&1' >> /tmp/webroot_all.txt
done

Cool thats working great. But I also want to remove the file once it scp the file from remore host to localhost. can we do that? Thanks

for i in srv1 srv2 srv3
do
    file=/path../webroot.txt
    ssh <user>@${i} "cat $file 2>&1;rm -f $file" >> /tmp/webroot_all.txt
done
