Definition: ls

(LiSt) The command in Unix/Linux, including macOS, that displays file names in the directory (folder). It is the counterpart to the DIR command in Windows and DOS. Following are some brief examples. Note that commands are case sensitive; for example, file names with upper case extensions must be expressed with upper case characters in the command; the same for lower case. See Unix commands and dot file.
