Shell Programming and Scripting

Hi All,

Could you please help me out how can i copy the file from one system to another using scp.

For example - i have systems A,B,C in one location
And i have systems D,E,F in second location.

Now, I wan to copy the files from Systems A->D, B->E, C->F using scp in loop or any condition statements...

Please help me out!!!

Hi

the syntax for scp is

Code:

scp <file to copied> <location to be copied>

either of the two arguments can be on a remote system
for a remote system the syntax is for the form
<user>@<pwd>:<location of the file>

if you need a series of interconnected scp transfers, i would suggest that you use password less login between the machines.

scp can also be performed as a ant tasks, if u require it.

cheers

thanks for the reply. I got the syntax,. but i want the loop to get the files transferred from a->d and other simultaneous systems.

Because if there are 20 systems on each location i need 20 scp's but if anybody tell me how we can do it through loop or condition statements?

hi sandeep

assuming you have predetermined list of servers , say A,B,C,D you may like to do

Code:

servers="A B C D"
for i in $servers
do
 for temServer in $servers 
  do
     if [ $i == $tempServer ] ; then
       continue
      else
        // your scp command goes here 
     fi
 done
done

this will giv you all the possible combinations for the servers.

hope it was of some use

Maybe it could be appropriate to use rsync.

Akshay,

It will work, but with all the permutation and combinations. the number of systems i am willing to scp the file is more, probably 30 in one location. so in total it will become 60 systems. so the loop will be more in the cycle than on actual scp statement.

To refigure.. my requirement is

System1="A B C D"
System2="E F G H"

Now SCP should be
first, from A -> E
Then, From B-> F
then, from C -> G .... so on...

Any help in this regard will be much appreciated ...
