dir and ll commands

What is the difference between the dir and ll commands?

Those aren't standard commands, I expect that they are aliased to some variant of ls. To find out, type

Code:

which dir
which ll

to find out if I'm right!

edit: oops, it seems dir is a command in its own right! damn my impatience!... OK, I'm as stumped as you now...
edit 2: I'm still pretty certain that ll will be aliased to ls though.

Hi,

As far as I know both dir and ll are aliases and not 'real' commands (external or internal).

Try alias from the command line and see which aliases appear and what they do, the ll and dir should be among them.

Hope this helps.

The only reason I second guessed myself was that here at work we have some RHEL boxes, and they do have a /usr/bin/dir binary (not a symlink). It even has a manpage!

edit: ah! some progress. Apparently, according to info dir, dir is part of the coreutils (on this RHEL box anyway). And I quote:

Quote:

File: coreutils.info, Node: dir invocation, Next: vdir invocation, Prev: ls \
invocation, Up: Directory listing

`dir': Briefly list directory contents
======================================

`dir' (also installed as `d') is equivalent to `ls -C -b'; that is,
by default files are listed in columns, sorted vertically, and special
characters are represented by backslash escape sequences.

*Note `ls': ls invocation.

In my experience, using "dir" produces the same output as "ls -l"
