Every Nth line position # (AWK)

A better way to show the file lines 3n + 1

How many files in the current directory ?

A simple "ls" lists files *and* directories. So we need to "find" the files (type 'f') only. As "find" is recursive by default we must restrict it to the current directory by adding a maximum depth of "1". If you should be using the "zsh" then you can use the dot (.) as a globbing qualifier to denote plain files: zsh> ls *(.) | wc -l for more info see the zsh's manual on expansion and substitution - "man zshexpn".

Quick searching with less

Detect illegal access to kernel space, potentially useful for Meltdown detection
