I want to learn how to use crontab. I see there are two manual pages:


Why are there 2 manual pages? What are the differences between them? Do I need to study both in order to use crontab, or is one authoritative?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


crontab(1) is the man page of crontab command.
crontab(5) is the man page of crontab file.

The man pages are divided in sections as described in What do the numbers in a man page mean?. Each section groups similar man pages. For example, Section 1 holds user commands (commands runable by all users in the system). Section 8 covers SysAdmin commands (i.e. the commands that demand root access to be run). Section 5 covers file formats. See the link above for more info.

Another example would be passwd(1) which describes the passwd command, and passwd(5) which describes the /etc/passwd file format.
