Copy A File To Multiple Machines At Once

This is a script I made up to help send files to multiple machines at once. Only one hickup that may occur...you have to have the same logon username and password on all machines....which in a business enviroment with a ldap backend this is fairly easy.

#!/bin/bash
username=$1
file=$2
path=$3
hostfile=$4

if [ -z $1 ]; then
echo " "
echo " "
echo " USAGE: multicopy.sh USERNAME FILE PATH HOSTFILE"
echo " "
echo " file- the file you wish to copy"
echo " NOTE: For multiple files give full path with each file and suround the list of files with double quotes ie: \"/tmp/file1 /tmp/file2/\""
echo " "
echo " path- the desintation path on the destination machines"
echo " "
echo " hostfile- a file containing the host names of the machines to transfer the file to"
echo " "
echo " "
exit 0

fi


servers=( `cat "$hostfile"`)

echo -n "Enter Password: "
stty -echo
read password
stty echo
echo ""  


i=1

for server in ${servers[@]}; do
expect -c "
spawn /usr/bin/scp $file $username@$server:$path
expect { 
"*password:*" { send $password\r\n; interact } 
eof { exit }
}
exit
"
let "i=i+1"
done

Once you have the file saved, make it executable either using graphical tools or from a console
chmod +x filename.sh the .sh extension tells the graphical enviroment that its a shell script

Run the script from a terminal multicopy.sh USERNAME FILETOTRANSFER PATHONREMOTESERVERS HOSTFILE where USERNAME is the username to use on all servers, FILETOTRANSFER is the file on the local machine that you want on the remote hosts, PATHONREMOTESERVERS is the path on the remote servers you want to put the file to, and HOSTFILE is a file containing all the hostnames or ip address of all the hosts you wish to transfer your file to.

For example: multicopy.sh bob wallpaper.jpg /tmp/ myhosts.txt and myhosts.txt could look like

192.168.1.100
192.168.1.101
192.168.1.102
192.168.1.103
192.168.1.104
