• You can do a keyword search by entering either of the following two commands (they are equivalent): man -k <some keyword> or apropos <some keyword>

• You can search for strings by entering /string[ENTER], where string is what you want to find. To search again, simply enter / alone. To search backwards, use ?

• See man less (really! less is now more) for details.

• The general statement for man is of this form: man [-<options>] [section] title

Find out about the man section numbers, what the main sections identifiers are and what they mean.

For example, crontab is found in both sections 1 and 5, so you must use man 1 crontab or man 5 crontab to select it (1 is the default here). Reference to one particular form of a command is usually shown in a form like crontab(1), crontab(5), or even crontab(1p) for some purposes.
