This code sets up a local copy of the noVNC project by creating a directory, checking if a "master" branch already exists, and cloning the repository from GitHub if necessary. It then lists the contents of the "novnc" directory and displays the current working directory.

Run example

npm run import -- "VNC HTML client"

VNC HTML client

mkdir -p novnc ; if git --work-tree=./novnc branch | grep master; then \
echo "Already checked out novnc"; \
else \
git clone https://github.com/novnc/noVNC.git ./novnc ; \
fi ; ls -la novnc ; pwd

#!/bin/bash

# Define the repository to clone
REPO_URL="https://github.com/novnc/noVNC.git"
REPO_DIR="novnc"

# Create the novnc directory if it doesn't exist
mkdir -p "$REPO_DIR"

# Clone the repository if the current branch is not the master branch
if! git --work-tree="$REPO_DIR" branch | grep -q master; then
  git clone "$REPO_URL" "$REPO_DIR"
fi

# Print the current working directory
echo "Working directory: $(pwd)"

# List the contents of the novnc directory
ls -la "$REPO_DIR"

This code snippet is designed to set up a local copy of the noVNC project. Here's a breakdown:

1. mkdir -p novnc:

   • Creates a directory named "novnc" if it doesn't already exist. The -p flag ensures that parent directories are created as needed.

2. if git --work-tree=./novnc branch | grep master; then ... else ... fi:

   • This is a conditional statement that checks if a branch named "master" already exists within the "novnc" directory.
   • git --work-tree=./novnc branch: Lists the branches within the "novnc" directory.
   • | grep master: Pipes the output of the git branch command to grep, searching for the string "master".
   • then echo "Already checked out novnc";: If "master" is found, it prints a message indicating that the "novnc" directory already contains a checkout of the project.
   • else git clone https://github.com/novnc/noVNC.git ./novnc; fi: If "master" is not found, it clones the noVNC repository from GitHub into the "novnc" directory.

3. ls -la novnc:

   • Lists the contents of the "novnc" directory with detailed information (permissions, size, etc.).

4. pwd:

   • Prints the current working directory, which should be the directory containing the "novnc" directory.
