Secure Copy Bash Script with Auto Path feature

This script sends a file from a project directory to the same project directory of another server, this will allow you to work in a project and update the server files in a very easy way.

Setup

First step is to set the setup variables inside the 'scp-auto-path' file.

_SERVER="localhost"
_USER="YOUR_USER"
_SERVERDIR="~/my-project/"
_LOCALDIR="/home/username/my-project"

Then you need to set the file as executable

$ chmod +x scp-auto-path

To execute in any directory you need to copy the executable to '/usr/bin/' or add the path to the user PATH variable (below an example to add it to .bashrc so you won't need to add it every time you open the console)

if [ -d "$HOME/scp-auto-path" ]; then
	PATH="$HOME/scp-auto-path:$PATH"
fi

Example of use

The command below will send the file '~/project-dir/src/lib/' to the remote server directory '~/project-dir/src/lib/'

~/my-project/src/lib/ $ scp-auto-path lib-example.c

For this file, this will be the same as:

scp /home/username/my-project/lib-example.c YOUR_USER@$localhost:~/my-project/src/lib/

How to create RSA key pair and send to server

To avoid writing the password everytime you send a file, you need to setup a RSA key pair and add it to authorized keys in the remote server.

$ ssh-keygen -t rsa

This will create the RSA key pair, you should keep the password empty! After creating the RSA key pair you need to send the public key to the remote server.

$ ssh-copy-id username@10.0.0.1

Now try to access the server with ssh, if it doesn't work, you should try to fix permissions in the remote server.
