I have a directory called MYPROJ. Underneath it are 10 sub-directories. My problem is everytime I want to execute a file in any of the directory under MYPROJ, I have to type ./filename. How do I avoid typing ./ for all the 10 directories under MYPROJ.
I have a file called amc.log. I want to delete the content of the file automatically every 3 days. How do I do that? Is there cron for that purpose?
