10 Daily Linux Questions and Answers Series (part 8)

In this brief article, I present 10 essential Linux questions along with their answers. This foundational knowledge is crucial for anyone seeking to master Linux. Q1: What is the difference between ls -l and ls -lh? ls -l shows file details in bytes, while ls -lh shows sizes in a human-readable format (KB, MB, GB). Q2: How do you list files with their full path? ls -d $PWD/* Q3: How do you list symbolic links only? ls -l | grep '^l' Q4: How do you check which file is using the most disk space in a directory? du -ah | sort -rh | head -n 10 Q5: How do you list files modified within the last 2 days? find . -mtime -2 Q6: Why might ls not show some files even though they exist? If files are hidden (starting with a dot), ls won't show them unless you use -a. Q7: How do you check the color coding used by ls? ls --color=auto Q8: What is the difference between ls and ls --color=auto? ls --color=auto enables color coding in the output based on file types. Q9: How do you list files without sorting them? ls -U Q10: How can you display file sizes in different units (KB, MB, GB)? ls -lh Stay tuned for part 9 coming tomorrow!
