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
