Basic File Operations Unix Quiz

In Unix-like shells, the ls command lists directory contents. The -l flag specifies the long listing format providing detailed permissions and metadata, while the -a flag reveals hidden files starting with a dot.

The 'cd ..' command moves up one directory level in the filesystem hierarchy. 'cd .' refers to the current directory, 'cd ~' goes to the home directory, and 'cd' alone also goes to the home directory. The double dot (..) is the standard parent directory reference in Unix/Linux.

The 'rm filename' command removes (deletes) a single file. 'mv' moves/renames files, 'cp' copies files, and 'rm -rf *' recursively deletes ALL files and directories in the current location - a dangerous command unrelated to deleting a single file.

The rmdir command is the standard Unix/Linux command to remove an empty directory. rm is used for files (unless used with -r), mv is for moving/renaming, and cd is for changing directories.

The 'mv oldfilename newfilename' command renames a file by moving it to a new name in the same directory. 'cp' copies files, 'touch' creates empty files, and 'rm -rf *' deletes everything. The mv command serves dual purpose: moving files between directories OR renaming within the same directory.
