How well do you know Linux? Which commands do you use most often?

I am well acquainted with Linux and use its commands daily for development and administration. Most commonly, I use:

• ls — to view directory contents.
• cd — to navigate the filesystem.
• grep — to search within text files.
• top or htop — to monitor processes and system load.
• ps — to view running processes.
• kill — to terminate processes.
• ssh — for remote server connections.
• tar, zip — for archiving and unarchiving files.
• find — to search for files based on criteria.
• chmod, chown — to manage access permissions.
• df, du — to check free disk space.

These commands enable efficient system management, analysis of system status, and automation of tasks.
