Using sed for files in multiple directories












0















I have a bunch of files in multiple directories with incorrect dates on the first line of each file. I am trying to write a script involving sed and a for loop.



Each file is in its own directory that is made up of the correct date. For example a file might be in: ./2014/06/02/record1 and I would like to replace the date on the first line to read '2014/06/02'.



There are a number of files each in their own directory. How do I use sed and a for loop to achieve this?

    I know there are similar questions but I specifically wanted to focus on the grabbing of part of a directory and using it within a for-loop and inserting into a file.
