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  A lucid how-to guide is available here

If you are ok with entering your password once for every run of the script  you can do so easily using an SSH master connection      usr bin env bash  USER AT HOST  user host     use   1  2  here if you like SSHSOCKET     ssh  USER AT HOST     This is the only time you have to enter the password    Open master connection  ssh -M -f -N -o ControlPath   SSHSOCKET    USER AT HOST     These do not prompt for your password  scp -o ControlPath   SSHSOCKET  file1 xy   USER AT HOST  remotefile1 xy scp -o ControlPath   SSHSOCKET  file2 xy   USER AT HOST  remotefile2 xy    You can also use the flag for normal ssh  ssh -o ControlPath   SSHSOCKET    USER AT HOST   echo hello  ssh -o ControlPath   SSHSOCKET    USER AT HOST   echo world     Close master connection  ssh -S   SSHSOCKET  -O exit   USER AT HOST

You can do it with ssh public private keys only  Or use putty in which you can set the password  scp doesn t support giving password in command line   You can find the instructions for public private keys here  http   www softpanorama org Net Application layer SSH scp shtml

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

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
