Using Files

[Shashidhar Yarabati]

Hi

I have a lot of files in particular folder. say "cvsadmin". It has lot of subdirectories, which itself contains lot of files in it.
What I want to do is: The file names which has ",v" extension needs to renamed.

I know we can do this for a particular file. But my folder has lots of files like this. I can go individually.

Could any body tell me the any solution?
Waiting for your reply..

You cant do it in a single command, if this is what you were asking.
If you are not sure, how to get a list of the all the files with a specified extension, then have a look at File.listfiles() method. This will give you a list of all immediate children of a directory. To drill down deep you can recursively process each child which is a directory.

BTW, not an advanced question.

Additionally, you can use File's renameTo method to rename the file.

Don't know your context but sometimes tasks may be accomplished easier without java, e.g. on linux/unix command line:

find . -name "*,v" -exec mv \{\} \{\}.new \;

will move all "*,v" files to "*,v.new".
