Saw a similar mapping on practice. Pretty sure this is correct: ls-t sorts by edited date, mkdir for making a dir, cp handles files, cp -r is used for directories, cd~ jumps to $HOME, cd/ to root, export sets env variables, mv moves files, touch creates files, and ls-l shows details. Let me know if someone disagrees but this looks solid.

Nice, this mapping tracks with bash basics. cp for files, cp -r for directories, ls -t sorts by modified date (descending by default), and ls -l gives detail view. cd~ is a shortcut to $HOME and cd/ is root. Mkdir, touch, and export are standard as well. Pretty sure these match up unless the test tries to trick with switches-agree?

• list files in directory sorted by edited date descending: is-t
• create directory: mkdir
• copy file: cp
• change directory to user $HOME: cd~
• create environment variable: export
• change directory to file system root: cd/
• move file: mv
• create file: touch
• list files in directory with details: is-l
• copy directory: cp -r

• ls-t → list files sorted by edited date
• mkdir → create directory
• cp → copy file
• cd~ → home dir
• export → set env var
• cd/ → root
• mv → move file
• touch → create file
• ls-l → details view
• cp -r → copy directory

Looks right based on the CLI basics. In practice labs and official docs, ls -l is for details and ls -t sorts by mod date. So mapping would be: cd~ to home, cd/ to root, mkdir for make directory, cp -r for directory copy.
