Documentation

Question 1

Manual section purposes

Answer 1

Most Unix documentation can be read from the command line.

Classic manual sections:

• system calls (2), subroutine API provided by kernel directly
• library functions (3) implemented by user space
• devices (4) - device drivers
• file formats (5) - … used by the kernel
  e. g. printf in 3 as a C library function (man 3 printf) but for the command line tool printf (man 1 printf) otherwise just get lowest numbered volume that knows this keyword.
