Unix Command Line ASCII Tree Directory Listing

From: "andrew cooke" <andrew@...>

The title says it all really.  I wanted one, had a poke round, found this
- http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/217212 - which
(if you delete the line
  print padding + '|'
to make things more compact) works like this:

andrew@... messaging > tree -f .

Unix tree Command

From: andrew cooke <andrew@...>

Date: Sat, 6 Aug 2011 16:24:08 -0400

I just noticed that this blog entry gets hits from google searches, so I
should update it with better information...

These days (and perhaps even when I wrote the original post) many Unixes
support the "tree" command, which gives you an ASCII "picture" of your
directories.

ASCII...

From: andrew cooke <andrew@...>

Ooops.  OK, so by default tree doesn't use ASCII.  But there's a command line
flag to make it do so:

  > tree --charset ascii .
  .
