dir

dir [options] [files...]

dir lists directory contents, equivalent to ls -C -b. By default, files are listed in columns sorted vertically, and non-graphic characters are displayed as C-style backslash escape sequences.Unlike ls, which changes its output format depending on whether output goes to a terminal or a pipe, dir always produces columnar output with escaped special characters. This makes it more predictable for scripting.The command is part of GNU coreutils and accepts the same options as ls.

Equivalent to ls -C -b. GNU coreutils specific; not available on all Unix systems. Use ls for maximum portability.

dir is part of GNU coreutils, written by Richard M. Stallman and David MacKenzie. It provides consistent columnar output with escaped special characters regardless of output destination.
