bash create many directories if it doesn't exist over ssh

Question

I want to create on a remote server2 many directories that already exist on the server1. My script on the server1:

LOG_DIR="/opt/server1/service/logs/"
DEST_HOST="server2"
DEST_USER="logger"
DEST_DIR="/volumes/storage/server1"

LISTEN_DIR=$(find $LOG_DIR -type d | tr '\n' ' ')

ssh $DEST_USER@$DEST_HOST " for Y in $LISTEN_DIR
                do
                    if [ ! -d  $DEST_DIR$Y ]; then
                        mkdir -p $DEST_DIR$Y;
                    fi
                done"

But on the server1 in directory /opt/server1/service/logs/ there are several other directories... Results of script:

[20:00 root@server1:~]# bash -x script.sh
+ LOG_DIR=/opt/server1/service/logs/
+ DEST_HOST=server2
+ DEST_USER=logger
+ DEST_DIR=/volumes/storage/server1
++ find /opt/server1/service/logs/ -type d
++ tr '\n' ' '

Answer 1

Try doing this :

find local_dir -type d -print0 |
ssh remote 'while IFS="" read -r -d "" a; do mkdir -p "remote_dir/$a"; done'

Or if you prefer a one-liner :

find local_dir -type d -print0 | ssh remote 'while IFS="" read -r -d "" a; do mkdir -p "remote_dir/$a"; done'

EXPLANATIONS

• find local_dir -type d : print all dirs from local_dir so STDOUT
• | : Unix pipe : branch STDOUT of the latest command to STDIN of the next one
• ssh remote 'remote_command' : ssh to a remote server, and execute a command. Single ' quotes are required to prevent the shell to interpolate $a variable
• while read a; do mkdir -p remote_dir/$a; done : the remote command, it reads on STDIN
• with mkdir -p, no need to check existence of any dir
