As I was verifying setuid and setgid bits on my executables this morning, I came across a program called chainsaw. To find out what a program does on a Linux box, you type “whatis <command>.” Example:
99% of the factory-installed commands are in the whatis database. The funny part here is that I asked it what a chainsaw was and it said that chainsaws were nothing appropriate. Which is good, as chainsaws really aren’t appropriate when dealing with Linux.
