Guys,
Any sample script that will copy file to remote server.I'm doing it on a manual process using SCP parameter. Tnx

well just put your scp command in a script, and it's "automatic". You've not given any information about what you want to automate about this. Only general improvement would be to use an ssh preshared key to bypass the need for manual password entry.

When copying files remotely (It also acts as my Off-site Backup Mirror), I use rsync and ssh to accomplish the task...

1. Add ssh keys to automate login without password prompt (there are lots of tutorial out there... google)

2. In my bash script, rsync command is:
Pull syntax:
rsync -avz -e "$SSH" --delete $USER@$HOST:/SRC/ /DEST/

Push syntax:
rsync -avz -e "$SSH" --delete /SRC/ $USER@$HOST:/DEST/

3. Make a script
# vi sync.sh

my script goes like this (you can copy & paste):

Code:

#!/bin/sh
#

RSYNC=$(which rsync)
SSH=$(which ssh)
RUSER=root                
HOST=192.168.0.10    
SRC=/shares/PUBLIC/       
DEST=/shares/BACKUP/      
PID=/var/run/sync.pid

start() {
        if [ ! -e "$PID" ];then
                touch $PID
                echo "Synchronizing files"
                $RSYNC -avz -e "$SSH" --delete $RUSER@$HOST:$SRC $DEST                              
                rm -f $PID
        fi
}

stop() {
        if [ -e "$PID" ];then
                killall rsync
                echo "Stopping filesynching"
                rm -f $PID
        fi
}
restart() {
    stop
    start
}

case "$1" in
        start)
                start
                ;;
        stop)
                stop
                ;;
        restart)
                restart
                ;;
        *)
                echo $"Usage: $0 {start|stop|restart}"
                exit 1
esac

exit $?

4. Dont forget to make your script executable and test it.
# chmod +x sync.sh
# ./sync.sh start

5. If you want to create cron, su as root and:
# crontab -e

and insert the ff:
# m h dom mon dow command
30 17 * * 1-5 /root/scripts/sync.sh start
30 7 * * 1-5 /root/scripts/sync.sh stop

Thats it! Hope that helps...
