ls

ls is a command to list files in Unix and Unix-like operating systems. ls displays files in a bare format. It is a shortening of 'list'. The list of arguments for ls include: * -l long format, displaying Unix file types, permissions, number of hard links, owner, group, size, date, and filename * -F appends a character revealing the nature of a file, for example, * for an executable, or / for a directory. Regular files have no suffix. * -a lists all files in the given directory, including those whose names start with "." (which are hidden files in Unix). By default, these files are excluded from the list. * -R recursively lists subdirectories. The command ls -R / would therefore list all files. * -d shows information about a symbolic link or directory, rather than about the link's target or listing the contents of a directory. * -t sort the list of files by modification time. * -h print sizes in human readable format. (e.g., 1K, 234M, 2G, etc.)
