Hm. I never will remember this. :(
I thought the same thing when I first started using UNIX, but it
eventually became habit.
_Usually,_ the section number doesn't really matter. It's only in cases
where the thing you are looking up has an entry in another section. For
example: the UNIX program /usr/bin/getopt has its man page as getopt(1),
but the getopt() function has its man page as getopt(3). By default,
"man" starts looking in section 1. So you can just do:
man getopt
..if you want to read about the /usr/bin/getopt program. But if you are
looking for how to use the getopt() function - something I always need
to look up, no matter how often I use it - you need to specify the section:
man 3 getopt
Similarly, to learn how to use the /usr/bin/crontab program, you would type:
man crontab
But to learn about the file format for the crontab file - and I always
do, because I tend to forget which field is day of the month - you need
to look in section 5:
man 5 crontab
