linux - What does the number in parentheses shown after Unix command names in manpages mean? -

-

for example: man(1), find(3), updatedb(2)? numbers in parentheses (brit. "brackets") mean?

it's section man page command assigned to.

these split

  1. general commands
  2. system calls
  3. c library functions
  4. special files (usually devices, found in /dev) , drivers
  5. file formats , conventions
  6. games , screensavers
  7. miscellanea
  8. system administration commands , daemons

original descriptions of each section can seen in unix programmer's manual (page ii).
