Shell Programming and Scripting

Hi,
I would like to parse all the files (*.c and *.h) in the sub-directories and if *.c or *.h files are found I would like to append a string and place it in the same directory. How do I do that?

For example:
I'm gonna operate on dir1 level.


$dir1/subdir1/test.h should be done as $dir1/subdir1/xyztest.h


like this I have to do all the sub directories in that directory.

Not tested, but it should work.

Code:

dir="/some/directory"
prefix="xyz"
find $dir -type f \( -name "*.c" -o -name "*.h" \) | while read f
do
  dirname=${f%/*}
  basename=${f##*/}
  mv "$f" "$dirname/$prefix$basename"
done
