recursive rename

Hello.Please help, how to rename recursive dirs, sub dirs and files in them.
This is the results of my experiments :

Code:

zarine@zomane:~/1a-script/recrensp$ find ./ -iname "*.bla" -exec rename -v -n 'y/A-Z/a-z/' "{}" \;
./DFg RgF/ffff dDd.bla renamed as ./dfg rgf/ffff ddd.bla

In this case "for a in "`find ./ -iname "*.bla"`"; do b=`echo $a | sed 's/A-Z/a-z/g'`; mv "$a" "$b"; done"
new lines( \n) are also quoted and of course the result is "No such file or directory", how to quote everything else without \n .
When I using rename ( perl script ) it renames some files but some not .Strange .

Quotes are not necessary around {}.

That will not work because you have quoted the output of find, thereby passing only one argument to for.

If you remove the quotes, it will fail if any filenames contain whitespace or other pathological characters.

The correct way is to pipe the output of find into a while ... read ... loop.

That sed command will only replace a literal "A-Z" with "a-z".
Use tr to convert to lowercase:
Code:
find ./ -iname "*.bla" |
 while IFS= read -r a
 do
   b=`printf "%s\n" "$a" | tr 'A-Z' 'a-z'`
   mv "$a" "$b"
 done"
If you are using ksh, you can save the calls to an external program with:
Code:
typeset -l b
find ./ -iname "*.bla" |
 while IFS= read -r a
 do
   b=$a
   mv "$a" "$b"
 done"
In bash, you can use a dynamically loadable builtin. See http://www.unixreview.com/documents/...6a/ur0606a.htm for details.

The Perl script version of rename is unreliable.

Thanks, now script reading line by line, but mv still says "No such file or directory"
I put your example in script :

Code:

#!/bin/bash
find ./ -iname "*.bla" |
 while IFS= read -r a
 do
   echo $a
   b=`printf "%s\n" "$a" | tr 'A-Z' 'a-z'`
   mv "$a" "$b"
 done

When I run the script the result is :

Code:

./DFg RgF/ffff dDd.bla
mv: cannot move `./DFg RgF/ffff dDd.bla' to `./dfg rgf/ffff ddd.bla': No such file or directory
./DFg RgF/dDFd dfdf.bla
mv: cannot move `./DFg RgF/dDFd dfdf.bla' to `./dfg rgf/ddfd dfdf.bla': No such file or directory
./rrr fff/fsfs.hhhh sfsdf.bla
mv: `./rrr fff/fsfs.hhhh sfsdf.bla' and `./rrr fff/fsfs.hhhh sfsdf.bla' are the same file
./rrr fff/sfsd.qq.r rr.bla
mv: `./rrr fff/sfsd.qq.r rr.bla' and `./rrr fff/sfsd.qq.r rr.bla' are the same file

.
After some time :
Ehhh, of course mv always will says "No such file or directory" in this case, dir "DFg RgF" exists, but "dfg rgf" not, first I must "mkdir" it

.

Use -depth when using find. This will go from the deepest to the shallowest. This will prevent you from renaming a directory which still has files yet to be renamed, which is what's happening now. The way you have it, a directory is renamed but then you try to rename a file within it using the old path name.

Code:

find -depth -iname "*.bla" | while read file; do \
  name=`basename $file` \
  newname=`echo $name | sed -r "s/[A-Z]/[a-z]/g"` \
  rename $name $newname $file \
done

I don't think so:

$ echo QWERTY | sed -r "s/[A-Z]/[a-z]/g"
[a-z][a-z][a-z][a-z][a-z][a-z]

ta0kira · 07-03-2007, 12:55 PM

Yeah, you're right. I was a little hasty with that one. I don't know what I was thinking.

Yes, tr does a better job like cfaj said. I remembered the way to translate with sed, but you need the whole set spelled out. In case the directories are also being renamed to lowercase, here is my modified version.

Code:

find `line` -depth | while read file; do
  name=`basename $file`
  newname=`echo $name | tr A-Z a-z`
  rename $name $newname $file
done

Paste that into the command line and press [enter], then type the base paths and press [enter] again.

PS cfaj: In your solution it looks like it will turn the entire path name to lowercase, which won't work. You can only rename the basename, to be qualified by the original dirname when renaming.

Fixnames is a GPL bash script that does recursive renaming a directories (top-level first) and files. it includes a --pretend option, full logging, simple detection of duplicate files, progress indicator.

it includes a sed line to make a tree a valid names on a fat/ntfs filesystem while removing multiple, trailing and leading spaces. it is well commented and should be easy to understand.

fixnames was developped for a mac->win migration which involved renaming of over 12k files
