Instead of hardcoding password in a shell script, use SSH keys, its easier and secure.
<pre><code>$ scp -i ~/.ssh/id_rsa *.derp devops@myserver.org:/path/to/target/directory/
</code></pre>
assuming your private key is at <code>~/.ssh/id_rsa</code> and the files you want to send can be filtered with <code>*.derp</code>
To generate a public / private key pair :
<pre><code>$ ssh-keygen -t rsa
</code></pre>
The above will generate 2 files, <code>~/.ssh/id_rsa</code> (private key) and <code>~/.ssh/id_rsa.pub</code> (public key)
To setup the SSH keys for usage (one time task) :
Copy the contents of <code>~/.ssh/id_rsa.pub</code> and paste in a new line of <code>~devops/.ssh/authorized_keys</code> in <code>myserver.org</code> server. If <code>~devops/.ssh/authorized_keys</code> doesn't exist, feel free to create it.

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.

SSHSOCKET=~/".ssh/$USER_AT_HOST"

# This is the only time you have to enter the password:

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.

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. I'll specify the password within the script, so that I don't have to enter it for each file.

在我的unix系统上，我的一个目录中有n个文件。有没有办法编写一个there脚本，通过scp将所有这些文件传输到指定的远程系统。我将在脚本中指定密码，这样就不必为每个文件输入密码。
