Need to create automated Directories
Hi,

On serverB i wish to have a script that creates ONLY & EXACTLY the same folder structure that i provide on ServerA.

Thus if serverA has a folder "Output" under /opt/app/Output and has the below folders under Output

Code:
 
Output
Output/logs
Output/reciever
Output/data
Output/reciever/tmp
...
...

I need the similar folder structure created on serverB. What should be the easiest way to achieve this ?

Just the folders not the files !!

Assuming you have a secure key exchange in place
Code:
find /opt/app/Output -type d -exec ssh $REMOTE_HOST mkdir -p {} \;

How can we specify the remote host directory ... if i wish to create the Output folder in /tmp/mydir of serverB ?

An ugly solution ...
Code:
find /opt/app/Output -type d | perl -ne '$_=~s{^/opt/app/}{/tmp/mydir/};system(ssh "$REMOTE_HOST "mkdir -p $_");' -

Probably a neater solution:-
Code:
cd /opt/app/Output
find . -type d -exec ssh $REMOTE_HOST "cd /tmp/mydir ; mkdir -p {}" \;

Untested though.... Smilie



I hope that this helps,
Robin

Wouldn't these run ssh and login for every single (sub-) directory found? Not sure the closing "+" instead "\;" could remedy that.

If the number of directories to make and therefore the number of SSH connections to make becomes a problem, then you could do this:-
Code:
cd /opt/app/Output

printf "cd /tmp/mydir" > /tmp/mkdir_cmds

find . -type d -exec printf "mkdir -p {} \n" \; >> /tmp/mkdir_cmds

sftp $REMOTE_HOST <<EOSFTP
put /tmp/mkdir_cmds
EOSFTP

ssh  $REMOTE_HOST "chmod 700 /tmp/mkdir_cmds ; /tmp/mkdir_cmds"

This will put all the commands into a file, send it and then execute it.

It's more to code (and I haven't checked it for errors) so unless creating so many SSH connections in a loop is a problem, I'd stick with the earlier suggestions.
