GNU Find never ceases to amaze me with its utility.

Yesterday I had to do an emergency restart of mysql in production and the resulting magento report/xxxx files swamped out everything else that I might have wanted to look at.

So specifically, I wanted to delete all the files that were created between a start and end date.

GNU find makes this easy

$ find . -type f -newer 655958024588 ! -newer 627812220533 -ls

This instructs find to list (-ls) all files (-type f) that are newer than a file called 655958024588 (-newer) and not newer than 627812220533 (! -newer).

If you do not have two files to act as date range boundaries, you can use touch to create them.

$ touch -t yyyymmddHHMM start_date_file
  $ touch -t yyyymmddHHMM end_date_file

Then supply these file names to -newer and ! -newer.

To delete the files we can use -exec.

$ find . -type f -newer 655958024588 ! -newer 627812220533 -exec rm -rf {} \;

Here it's the -exec argument does the heavy lifting. {} is a placeholder for the file name (find substitutes '{}' with each found filename) and \; terminates the command sequence (much like it does in regular bash).
