Linux

& -- is to run program in the background

find . -name  * -exec ls -a {} \;

{} means "the output of find". As in, "whatever find found". find returns the path of the file you're looking for, right? So {} replaces it; it's a placeholder for each file that the find command locates

The \; part is basically telling find "okay, I'm done with the command I wanted to execute".
