To open or edit code in Linux server

we can use various terminal-based editors depending on what's installed on your Linux server. Here are a few ways to do it:

For example, the code resides in /var/www/proj_management.

🛠️ View files in the project directory:

bash
ls -la /var/www/proj_management

---

✏️ Edit a specific file (e.g., index.php):

Using nano (simple editor):

bash
sudo nano /var/www/proj_management/index.php

Using vim (powerful, but has a learning curve):

bash

sudo vim /var/www/proj_management/index.php

Using code (if Visual Studio Code CLI is installed):

bash
sudo code /var/www/proj_management


If you're accessing the server via SSH and want to edit with a GUI-based editor like VS Code on your local machine, 
you can use Remote - SSH extension in VS Code.

----------------------------------------------------------
If you want to use Remote - SSH extension in VS Code to open and work with files on a remote Linux server (like your /var/www/proj_management directory), here’s a quick setup guide:
✅ Step 1: Install Remote - SSH Extension in VS Code
Open VS Code.
Go to the Extensions panel (Ctrl+Shift+X).
Search for “Remote - SSH”.
Click Install.
✅ Step 2: Add SSH Configuration
Press Ctrl+Shift+P to open the Command Palette.
Type Remote-SSH: Add New SSH Host and select it.
Enter your SSH command, e.g.:
bash
ssh your_username@your_server_ip
Choose the SSH config file to save this entry (usually ~/.ssh/config).

✅ Step 3: Connect to the Server
Open the Command Palette again (Ctrl+Shift+P).
Select Remote-SSH: Connect to Host.
Choose your saved server from the list.
VS Code will open a new window connected to the remote server.

✅ Step 4: Open Your Project Directory
Once connected:
Click File > Open Folder.
Enter:
bash
/var/www/proj_management
You now have full access to browse, edit, run, and debug the code remotely as if it's on your local machine.
