1. ls – List Directory Contents

ls
ls -l   # Detailed listing
ls -a   # Include hidden files

2. cd – Change Directory

Navigate through your system’s file structure with cd. Whether you're jumping into a project folder or heading home, this command gets you there.

cd /var/log
cd ~         # Go to home directory
cd ..        # Move up one level

3. pwd – Print Working Directory

Need to know exactly where you are in the file system? Use pwd to print your current path.

pwd

4. mkdir – Make Directories

Create new folders with mkdir. You can even create nested directories using the -p flag.

mkdir my_project
mkdir -p parent/child/grandchild

5. rm – Remove Files or Directories

This powerful (and dangerous) command deletes files and directories. Use it carefully—especially with recursive flags.

rm file.txt
rm -r my_directory
rm -rf /   # Don't do this unless you want to nuke your system!

6. cp – Copy Files and Directories

Use cp to duplicate files or folders. It's great for backups or moving things around safely.

cp file.txt backup_file.txt
cp -r dir1 dir2   # Copy directories recursively

7. mv – Move or Rename Files

Whether you're relocating a file or renaming it, mv has you covered.

mv oldname.txt newname.txt
mv file.txt /home/user/Documents/

8. touch – Create Empty Files

touch is a quick way to create a blank file. It's also useful for updating file timestamps.

touch newfile.txt

9. cat – Concatenate and Display Files

Want to view file content quickly? cat is perfect for displaying text in the terminal.

cat file.txt

10. grep – Search Text Using Patterns

grep lets you search through files for specific patterns. It's incredibly powerful when dealing with logs or configs.

grep "error" /var/log/syslog
cat file.txt | grep "keyword"
