copying folder and changing extension of files in it?

stratotak · 03-08-2009, 12:46 PM

IM trying to figure out the command I would use to copy contents of a folder and change the extension of the files within the folders.For example..I have main folder.. Folder A..in that folder are folders..folder 1,folder 2,folder 3,etc..and in each folder are files.I need to change the extensions of the files from .ewav to .wav..and keep the folder structure.

To rename your files with '.ewav' extension to files with '.wav' extension:

rename .ewav .wav *.ewav

This will work in the directory in which you run the command. I don't understand what you are trying to do with the copy command, copy what to where?? If you need to rename files with this extension in multiple folders?? Not sure how you would do that with a single command.

Well..Im getting closer to figuring it out..trying different variations of commands..hers a test folder of what im trying to do..maybe someone else knows how to get the rest of the way..I figured out how to copy folder and keep folder structure intact..just having issue with renaming the files to just change there extension..

Im stuck at renaming part..Im not even sure that is the correct command..and Im assuming the errors I am getting are from the files having spaces in there names..First question is can I easily get rid of the spaces and replace them with a "_"..and then if that rename command is right.This is just a test trying to figure out the right commands..Im not trying to change a.wav to a text file..Its just the extension I used..could have been .mp3,.avi...etc..And If i can get the rename command i should be able to do this with just one command.

Code:

  cp -r   backup && rename ????????

Question marks are the unknown correct command

Tinkster · 03-09-2009, 04:00 AM

I don't know whether rename will handle the wildcards gracefully,
but you got the syntax round the wrong way ...

rename .wav .txt backup/*/*.wav

stratotak · 03-09-2009, 05:05 AM

well little by little im getting closer..lol..after googling a bit i found command to remove spaces..

Code:

rename -v 's/\ /\_/g' *

the "*" is how deep the folder structure it goes..
http://zona90.wordpress.com/2008/11/...inux-commands/
still have issue with renaming though

In the past, I would download my updates on high speed internet at a different location because one of my residences has dial-up. I would use firefox in Debian, but downloaded to a FAT32 USB stick, for some reason it would download the file with correct name but would add a second extension, example:

package.rpm became package.rpm.rpm

This is how I would rename the files to remove the second extension, this command would have to be run from the directory containing the double extension files:

for i in *.rpm.rpm; do mv "$i" "`basename $i .rpm.rpm`.rpm"; done

Try adding this (below) to your command, make sure to have a recursive option in the right place to do it recursively.

for i in *.ewav; do mv "$i" "`basename $i .ewav`.wav"; done

Junior Hacker · 03-09-2009, 05:39 AM

BTW:
Using that command does not require you to remove spaces as the wildcard (*) is before the extension.

stratotak · 03-09-2009, 06:28 AM

but that way wont do multiple directories?I would have to cd into each directory where files are.Which isnt bad if it 1-2-3 directories but like 20 or so..I found this way of doing it but cant seem to get the context right..Ill have to work on it later..His uses "f" instead of "i"
http://thetechforums.net/howToLinux/?p=19
Folder Im going to convert has like 30-40 folders or so and some folders contain 1-2 .ewav files and some contain 10 or so..so cding into each directory and doing this is quite tedious..I might just have to boot into windows to do this..I had done this before last year or so and used a free utility to rename .ewav to .wav .. it was just a matter selecting folder and right click..and it handled all the files in subfolders.

stratotak · 03-09-2009, 07:30 AM

ok..just incase anyone else needs to change alot of files extensions in multiple directories..I downloaded a little windows app that works perfect in wine..just drag and drop folder onto it and it works perfect..its called ezXTN..

jschiwal · 03-09-2009, 07:37 AM

This might work for you:
eval $(find test/ -type f -name "*.ewav" | sed -n '/ewav/s/$.*$.ewav/mv "\1.ewav" "\1.wav/p"')

If the list is very long, then instead of using eval, redirect the output to a script and execute the script.

stratotak · 03-09-2009, 07:49 AM

yeah..but that sure is alot to type.and to remember.its kinda hard to beat drag&drop..like i said..that little windows app works great in wine..tried another one called extension changer..works well under wine to..Would think that someone would have developed at little app to do this in linux..??

millgates · 03-09-2009, 08:06 AM

i believe there's an application called Bulk Rename or something like that that could do that
i guess it's part of kde but i'm not sure about that

David the H. · 03-09-2009, 08:17 AM

The perl rename command is probably the easiest way to rename files, as has been mentioned above. It's syntax is pretty much identical to sed.

Another way you could do it is with parameter substitution.

Code:

for i in *; do

mv $i ${i%.ewav}.wav

done

You can replace * with whatever command you use to generate the filelist, of course, such as "$(find .)".

stratotak · 03-09-2009, 11:46 AM

I searched through synaptic and found a few rename apps..PyRenamer seems to be what i was looking for.It will do everything I need,I can set it to do a directory and all its subfolders...it will remove spaces and replace with "_"..and change extension all with 1 click..

All you have to do is make a oneliner script from it, and copy it to your ~/bin/ directory. Then run the script when you need to.

No need to use a windows app. You never know where it's been!
