The pwd command displays your current working directory, while man provides the manual for any command. For instance, to access the manual for ls, simply type man ls. The clear command is handy for clearing the terminal screen.
The grep command is a powerful tool for searching specific text within files. You can utilize options like -r for recursive searching and -i for a case-insensitive search. An example command is grep "example" file.txt to find the word "example" in "file.txt".
