The first manual page ever written for unix was said to cover the `cat'
utility, and was said to have been written by this guy here, Dennis Ritchie,
who happens to also be inventor of the C programming language.
man <name of command>For example, to learn more about the `kill' command, you could type:
man killThe flaw in `man' is that you need to know the name of the command you want help on before you ask for it. Actually this is only partially true - you can look up a word in a manual page description using the `-k' parameter:
man -k killAlso of use to know: the manual has several numbered sections as follows (usually):
man 1 whoThat is unless you're using Solaris (or possibly another SystemV-derived unix)
man -s 1 whoUsually the man command will give you the first manual entry it finds, so
man whoWill find who most likely in section 1.
