Viewing & Editing Text Files in Linux
cat displays entire file contents (good for small files). less allows scrolling through large files with keyboard navigation (q to quit, space/b to move pages). head shows the first 10 lines by default (head -n 5 for custom count). tail shows the last 10 lines and is useful for monitoring logs in real-time with tail -f. nano is a beginner-friendly text editor: type normally, use Ctrl+O to save, Ctrl+X to exit.
For quick viewing: cat file.txt. For large files or logs: less file.txt or tail -f logfile.log. nano is perfect for editing config files; vi/vim are advanced editors offering powerful features but steeper learning curves. Always verify file contents with cat or head before editing to avoid mistakes.
