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).
