Which command displays file names only and no additional information?

The ls command is used to list the files and directories in a given path. By default, the ls command

displays only the file names, without any additional information. However, the ls command can also

take various options to modify its output. For example, the -l option tells ls to display the long

format, which includes the file permissions, owner, group, size, date, and name. The -h option tells ls

to display the file sizes in a human-readable format, such as KB, MB, GB, etc. The -a option tells ls to

display all files, including the hidden ones that start with a dot (.). The -n option tells ls to display the

numeric user ID and group ID instead of the user name and group name. Therefore, the only option

that does not add any additional information to the file names is the -a option. The command ls -a

will display all the file names in the current directory, including the hidden ones, but nothing

else. Reference:
