Automate scp file transfer using a shell script

Question

I have some n number of files in a directory on my unix system. Is there a way to write a shellscript that will transfer all those files via scp to a specified remote system

Answer 1

you could also use rsync. It seems to work better for multiple files than scp IMHO.

rsync -avzh /path/to/dir/ user@remote:/path/to/remote/dir/

Update

You can use rsync via ssh by adding the '-e' switch:

rsync -avzh -e ssh /path/do/dir/ user@remote:/path/to/remote/dir/

Answer 2

#!/usr/bin/expect -f
spawn scp -r BASE.zip abhishek@192.168.1.115:/tmp
expect "password:"
send "wifinetworks\r"
expect "*\r"
expect "\r"

Answer 3

rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speed up file transfers when the destination file is being updated.

The rsync remote-update protocol allows rsync to transfer just the differences between two sets of files across the network connection, using an efficient checksum-search algorithm described in the technical report that accompanies this package.

Copying folder from one location to another

   #!/usr/bin/expect -f   
   spawn rsync -a -e ssh username@192.168.1.123:/cool/cool1/* /tmp/cool/   
   expect "password:"   
   send "cool\r"   
   expect "*\r"   
   expect "\r"  

Answer 4

Instead of hardcoding password in a shell script, use SSH keys, its easier and secure.

$ scp -i ~/.ssh/id_rsa *.derp devops@myserver.org:/path/to/target/directory/

assuming your private key is at ~/.ssh/id_rsa and the files you want to send can be filtered with *.derp

To generate a public / private key pair :

$ ssh-keygen -t rsa

The above will generate 2 files, ~/.ssh/id_rsa (private key) and ~/.ssh/id_rsa.pub (public key)

To setup the SSH keys for usage (one time task) : Copy the contents of ~/.ssh/id_rsa.pub and paste in a new line of ~devops/.ssh/authorized_keys in myserver.org server. If ~devops/.ssh/authorized_keys doesn't exist, feel free to create it.

Answer 5

why don't you try this?

password="your password"
username="username"
Ip="<IP>"
sshpass -p "$password" scp /<PATH>/final.txt $username@$Ip:/root/<PATH>

Answer 6

The command scp can be used like a traditional UNIX cp. SO if you do :

scp -r myDirectory/ mylogin@host:TargetDirectory

will work
