What is the typical purpose of the /tmp directory in Unix-like systems?

• A. Temporary files that can be deleted
• B. System binaries
• C. User home directory
• D. Configuration files

Answer: (A)

Temporary storage for files created by programs during execution, meant to be ephemeral and non-persistent. /tmp is typically world-writable with a sticky bit, allowing anyone to place temporary files but preventing users from deleting others’ files. It can be cleared on reboot or purge on a schedule, and on some systems it’s mounted as tmpfs for speed. This isn’t for system binaries (those live in /bin or /usr/bin), isn’t the user’s home directory (/home), and isn’t for persistent configuration files (usually /etc or dotfiles). So the intended purpose is to hold temporary files that can be deleted.
