From the website: What is KRename ? Rename is a powerful batch renamer for KDE. It allows you to easily rename hundreds or even more files in one go. The filenames can be created by parts of the original filename, numbering the files or accessing hundreds of informations about the file, like creation date or Exif informations of an image. http://www.krename.net/ -- Colin Brace Amsterdam ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Sure, its not as crazy as krename (it wont read any metadata), but it runs in a terminal, is written in C and supports extended regular expressions.

Best way is with ports/misc/mmv:
mmv ?* =l1=2
If you use zsh, you can use the zmv function to do the same thing:
autoload -U zmv
zmv '([A-Z])(*)' '${(L)1}$2'
Both of the above will detect filename collisions and tell you what
won't work. If you know there aren't any collisions, you could do this
(zsh again):
for i in [A-Z]* ; do
mv $i ${i[1]:l}${i[2,-1]}
done

I happen to batch rename songs etc. which almost invariably have white spaces and other horrors. So i use something like mv $i `echo $i|sed -e 's/ */_/g' -e '.' ` Sed has the advantage you can do several transformations at one stroke, and fine tune the transformations.

Re: Shell script--batch rename files
mvb (MV-Batch shell script) To the several people who wrote to me about my batch-rename shell script, and anyone else who may be interested, I have worked a lot on it the past few days and the latest version (1.5.5) and a screenshot and README is at: http://www.xscd.com/pub/mvb/ I'll try to keep subsequent versions, if any, in the same location. Because I am learning shell scripting, I appreciate any criticisms, comments or suggestions from more proficient programmers and users. The script works well for me, especially for quickly renaming image files that have been downloaded from my digital camera or from the Internet and sorted into directories by theme.

Shell script--batch rename files
Hello All--
I'm a novice shell programmer, but I thought I would begin to learn
by writing a script that had a need for but could not find an
equivalent of on the Internet. I decided to post it here (a) in case
anyone else might find it useful and (b) to expose it to more
experienced script authors who might be kind enough to offer
helpful criticisms or suggestions.
(the script appears in its entirety at the end of this email)
I wrote the script (it works with /bin/sh or BASH) to address the following
problem-- I have many folders of image files (from my digital camera,
received as email attachments or downloaded from the Internet) that I have
sorted into folders by theme (such as friends, family, vacation_2003,
etc.), and many of them have filenames I would like to change on a
per-directory basis, either because they are too generic
(IMG_0105.JPG, IMG_0106.JPG, etc.), or because the filenames have spaces or
unusual characters within them, or simply to make all the filenames
in each directory have the same root name with a unique numerical index
appended, maintaining their original filename extension (or adding
one, if desired).
The script works on files in the shell's current directory only
(and not on any subdirectories within), and renames every file
(but not subdirectories or symbolic links) using a user-specified
name followed by a numerical index, followed by the file's original
filename extension (if there was any).
On my machine I have titled the script mvb (like a batch version
of mv), and it seems to work well so far during the couple months
I have been working on it. Like I said, I post it here in case
anyone else may find it useful and to learn from any criticisms,
comments and suggestions it might generate.
Thank you,
Steve

INFORMATION
This shell script (Bourne or BASH) will RENAME all visible files
(files that don't begin with a dot) in the current directory, to
a name you specify, appending a numerical index to each filename
so that each is unique, and retaining the original filename
extension, if one exists.
This script will NOT rename subdirectories or symbolic links
contained within the current directory, nor will it descend into
subdirectories to rename files within them.
If the script does not see what looks like an existing valid
FILENAME EXTENSION (3-4 characters following a dot at the end
of a filename), it will ask for one. If you WANT to add a
filename extension, just type 3 or 4 characters (i.e. jpg, txt,
html), with or without a preceding dot--the script will provide
the dot if you do not. If you do NOT want the filename to have
an extension, just press RETURN or ENTER at that prompt without
typing any characters, and no filename extension will be added.
