Effortless Folder Creation: You can create multiple directory combinations at once by using mkdir -p followed by the directory path with sections in curly braces. For example,
mkdir -p ./home/{a,b}/{x,y,z}.
Backtrack Fast: Instead of repeatedly typing cd .. to go back, simply use cd - to return to your previous directory immediately.
Bulk File Generation: Create a large range of numbered files in seconds using the touch command with braces. For example, touch file{1..100}.txt will instantly create 100 text files.
Real-time Log Monitoring: To watch a log file as it updates, use tail -f [filename]. The -f flag "follows" the file, so you see new lines of data as they are added in real-time.
Quick Command History: If you need to see your most recent actions, use history followed by a number (e.g., history 5) to display exactly that many of your last commands.
