// Check binary availability
if (!shell.which('git')) {
shell.echo('Sorry, this script requires git');
shell.exit(1);
}

shell.cp('-R', 'source/', 'dest/');
// Remove files and directories
shell.rm('-rf', 'build/');

Navigation & Executing Shell Binaries
// Navigation
shell.cd('dist');
console.log('Current directory:', shell.pwd().toString());
// Execute command synchronously
const result = shell.exec('git rev-parse HEAD');
if (result.code !== 0) {
shell.echo('Git command failed');
} else {
shell.echo(`Commit hash: ${result.stdout.trim()}`);
}

// Search text matching regex in files (like grep)
const matches = shell.grep('TODO', 'src/*.js');
// Pipe commands together
shell.cat('input.txt').grep('ERROR').to('errors.log');
