read the transcript!
man pages are split up into 8 sections
1 2 3 4 5 6 7 8
$ man 2 read
means “get me the man page for read
from section 2”.
There’s both
- a program called “read”
- and a system call called “read”
So
$ man 1 read
gives you a different man page from
$ man 2 read
If you don’t specify a section, man will look through all the sections & show the first one it finds.
