recursively move types of files

recursively move types of files

[Charles L. Snyder]

Hi

I have 2 separate but file management - related questions (emacs
22.2.1, mac leopard system):

1. I want to move all .pdb files from a folder (and all its
subfolders):

/Users/cls/ebooks

to another folder:
 /Users/cls/pdb_files

I can find all the files with Alt-x find-dired RET ~/ebooks RET -name
"*.pdb" RET
but how do I mark and move the files within emacs?

2. I have a huge number of files named like this
"Report_work_01232008_blah.pdf", and I want to replace all the "_"
with " "
ie., "Report work 01232008 blah.pdf"
Some files have one underscore, some have many more.

When I Crtl-x d to the folder, and mark all files containing (% g RET
_ ) an underscore, there are several problems:

- it doesn't search and mark files in the the subdirectories / nested
folders

- only the first underscored in the filename is changed, not all of
them  (how do I fix the regex for "_")

- I sometimes get a 'maximum buffer size exceeded'.

Thanks in advance

Since originally none of the files are marked, dired-toggle-marks (bound
to `t') marks them all.  Then dired-do-rename (bound to `R') will move
them.

It's probably better to do it outside dired-mode, in a *shell* buffer:

	find <directory> -type f -exec trans.sh {} \;

maybe added with a -name <pattern> option and a shell script trans.sh  
like:

	#!/bin/sh
	dir="`dirname $1`"
	fil="`basename $1`"
	new="`echo "$fil" | tr _ ' '`"
	mv "$1" "$dir/$new"

or in bash:

	#!/bin/bash
	dir=$(dirname $1)
	fil=$(basename $1)
	new=$(echo "$fil" | tr _ ' ')
	mv "$1" "$dir/$new"

Why that?  I'd switch to wdired-mode and do a query-replace followed by
C-c C-c.  No need to write a shell script.

To serial rename files you can also use:
http://www.emacswiki.org/cgi-bin/wiki/SerialRename
(Not sure it will work with space, it's a long time i don't check this code)
Tought it's a bad idea to name files ala losedows with spaces.
