'tren' is a general purpose file and directory renaming tool. Unlike
commands like 'mv', 'tren' is particularly well suited for renaming
*batches* of files and/or directories with a single command line
invocation. 'tren' eliminates the tedium of having to script simpler
tools to provide higher-level renaming capabilities.
'tren' is also adept at renaming only *part of an existing file or
directory name* either based on a literal string or a regular
expression pattern. You can replace any single, group, or all
instances of a given string in a file or directory name.
'tren' implements the idea of a *renaming token*. These are special
names you can embed in your renaming requests that represent things
like the file's original name, its length, date of creation, and so
on. There are even renaming tokens that will substitute the content
of any environment variable or the results of running a program from a
shell back into the new file name.
'tren' can automatically generate *sequences* of file names based on
their dates, lengths, times within a given date, and so on. In fact,
sequences can be generated on the basis of any of the file's 'stat'
information. Sequence "numbers" can be ascending or descending and
the count can start at any initial value. Counting can take place in
one of several internally defined counting "alphabets" (decimal, hex,
octal, alpha, etc.) OR you can define your own counting alphabet.
This allows you to create sequences in any base (2 or higher please :)
using any symbol set for the count.
'tren' is written in pure Python and requires Python version 2.4.x or
later. (It *may* run with Python 2.3.x, but has not been tested with
this older release.) It has not been tested with Python 3.x.
'tren' is known to run on various Unix-like variants (FreeBSD, Linux,
MacOS X, cygwin) as well as Windows. It will also take advantage of
'win32all' Python extensions on a Windows system, if they are present.
