Subject: a script ive been using to get the top most recently modified files
 in a folder recursively. i have another version of this script with the
 option for file exclusion and outputs how long it took to run. also a script
 i used to kill vscode-server processes that were destroying my laptop when
 using vscode ssh from desktop
