Mucho esta explicado en los "man" pages.
Solo haces "man" y el nombre del comando.
Por ejemplo "man grep":

strawberry> man grep
NAME
grep, egrep, fgrep - print lines matching a pattern
SYNOPSIS
grep [options] PATTERN [FILE...]
grep [options] [-e PATTERN | -f FILE] [FILE...]
DESCRIPTION
Grep searches the named input FILEs (or standard input if no
files are
named, or the file name - is given) for lines containing a match
to the
given PATTERN. By default, grep prints the matching lines.
In addition, two variant programs egrep and fgrep are available.
Egrep
is the same as grep -E. Fgrep is the same as grep -F.
OPTIONS
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching
lines.
Places a line containing -- between contiguous
groups of
matches.
-a, --text
Process a binary file as if it were text; this is
equivalent to
the --binary-files=text option.
-B NUM, --before-context=NUM
Print NUM lines of leading context before matching
lines.
Places a line containing -- between contiguous
groups of
matches.
-C NUM, --context=NUM
Print NUM lines of output context. Places a line
containing --
between contiguous groups of matches.
-b, --byte-offset
Print the byte offset within the input file before each
line of
output.
--binary-files=TYPE
