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.)
