🔍 grep - Search Text Looking for specific information/string within files? The "grep" command can do the job! 🔎 Use "grep keyword filename" to find all occurrences of "keyword" in the given file.

grep -l "unix" * #Display the file names that matches the pattern
grep -i "UNix" file1.txt #Case insensitive search
grep -n "unix" geekfile.txt #Show line number while displaying the output using grep -n

🔄 pwd - Print/Present Working Directory Lost in the terminal jungle? 🌳 The "pwd" command is like a compass; it shows you the full path of the current directory. Type "pwd" to know exactly where you are.
