In Linux, to get help or to read documentations on a particular command we can use either of the three ways : man, info or pinfo .

The help command man is more popular and gives a concise documentation of how to use a command, whereas the info or pinfo are the GNU documentations which are more detailed.

I personally liked pinfo the most, maybe because I come from a windows background, but I guess I will use man more 😀

To get help with any of these documentation commands, just write the documentation command followed with the command with which you need help. Example:

man date

or

pinfo date

or

info date
