tdir \- Display formatted directory listing
tdir [-DRdefhtv] [-c\fICol Width\fP] [-s\fISep Character\fP] [-w\fIOutput Width\fP] [dir ...]
tdir displays a formatted listing for the directories you select,
grouping the file names by "extension".  If you do not name a
specific directory, it defaults to the current directory.

For each directory selected, tdir will first display a columnated and
sorted list of subdirectories delimited by square brackets, followed
by a columnated list of files sorted by "extension" which appears on the
left side of the listing delimited by curly braces.

If either a directory or file name cannot fit in the column width, it will
be truncated so that it does fit.  In that case, the last character of
the truncated name will be replaced with a carat (^) to let you know
what happened.

The output is written to the standard output.

Normal exits return an exit status of 0.  Command line errors or
unreasonable parameters return an exit status of 2.

.B -D
Supress output of "dot" directories and files. i.e., Files and directories
whose names begin with "."  This option is ignored when viewing
directory tree output (-t or -Rdf).
.B -R
Travel down each directory tree Recursively. Defaults to
no recursion.
.B -d
Suppress display of directories
.B -e
Suppress sorting files by extension.  Display full file name
in alphabetic order beneath the directory display.
.B -f
Suppress display of files
.B -h
Display Help information about tdir.
.B -s c
Set Extension Separator character to c. (default: .)
tdir will search for the rightmost instance of this character
when examining file names.  From that position to the end of
the name is considered the "extension" of the file.  Everything
before it is considered the "name".
.B -t
Tree mode - display directory tree only.  Equivalent to: -Rdf
.B -v
Display Version information about tdir.
.B -c #
Set Column With to # characters. (default: 19)
.B -w #
Set the Output Width to # characters.
On Unix-style systems, this defaults to the current terminal
width minus 1.  On other systems it defaults to 80.
tdir defines its columnar output based on the total output width and
column width.  Both of these can be changed from the command line.
The number of columns is (output-width modulo column- width).  The
indentation to the first column is (remainder
output-width/column-width).  The width of the text is always one less
than the column width to leave room for a trailing space.
tdir sorts and displays file names based on their so-called "extensions".
In most cases, the default of '.' should be fine.  However, there may
be times when you want to override the default (with the -s command
line option).  Say, for example, you have a bunch of reports ending
in: -001, -002, -003, and so on.  In this case, switching the separator
character to '-' will probably give you a more reasonable output
sort order.
You must have a reasonably current copy of 'python' installed for tdir
to operate.
None known as of this release.  tdir is written in 'python' and has
been used on FreeBSD, Linux, and Windows 2000/XP installations.  If you are
using something else that supports 'python', give it a whirl.

tdir is case-sensitive.  So, files ending in ".EXE" and ".exe" and
".eXe" will sort into separate groups.  This is completely appropriate
for adult operating systems like Unix, but (at the very least)
arguable for systems like Windows where case is preserved but not
observed by the OS.

Paths are displayed using '/' as the path separator.  I can't help it
that Microsoft departed from The One True Way ;))

If you install tdir on a FreeBSD system using the 'ports' mechanism, you will
also find this file in /usr/local/share/doc/tdir.
