port share

To create a custom shell command on your Mac for running the ssh arifpro@srv.us -R command with flexible port options, you can define a shell function or script. Here’s how to do it:

---

Requirements

• SSH Access: You need SSH access to the server srv.us with the username arifpro.
• Shell Configuration: You should have a .zshrc or .bashrc file in your home directory.
• ssh-keygen -t ed25519 to generate a new SSH key pair and add it to the github account to use github username to share the port.

---

Option 1: Add a Shell Function in Your .zshrc (or .bashrc)

1. Open your shell configuration file:

   nano ~/.zshrc
   

   (Replace .zshrc with .bashrc if you’re using Bash.)

2. Add the following function:

   port() {
       local username="arifpro"
       local server="srv.us"
       local port_args=""
   
       # Process arguments
       for port in "$@"; do
           port_args="$port_args -R ${port}:localhost:${port}"
       done
   
       # Run the SSH command
       ssh "${username}@${server}" $port_args
   }
   

3. Save and apply the changes:

   source ~/.zshrc
   

4. Usage:

   • For a single port:

     port 5001
     

   • For multiple ports:

     port 5001 3000

Option 2: Create an Executable Script

1. Create the script file:

   nano ~/bin/port
   
   # or we can create the file and open it in VS Code
   
   # **Open Terminal**:
   mkdir -p ~/bin
   
   # **Create the Script File**:
   touch ~/bin/port
   
   # **Open the Script in VS Code**:
   code ~/bin/port
   

   (If ~/bin doesn’t exist, create it: mkdir ~/bin and add it to your PATH by editing ~/.zshrc or ~/.bashrc to include export PATH="$HOME/bin:$PATH".)

2. Add the script content:

   #!/bin/bash
   username="arifpro"
   server="srv.us"
   port_args=""
   
   # Process arguments
   for port in "$@"; do
       port_args="$port_args -R ${port}:localhost:${port}"
   done
   
   # Run the SSH command
   ssh "${username}@${server}" $port_args
   

3. Make the script executable:

   chmod +x ~/bin/port
   

4. Usage:

   • For a single port:

     port 5001
     

   • For multiple ports:

     port 5001 3000

Explanation

• Dynamic Ports: The script/function loops through all provided arguments and creates -R mappings dynamically.
• Custom Command: You use a simple command (port) instead of the full ssh syntax.
• Reusable: Add as many ports as needed in one command.
