Q . Learn more about the man command itself with man man.
There are many more commands than listed in this chapter. For information
about other commands or more detailed information, the O’Reilly publication
Linux in a Nutshell is recommended. In the following overview, the individual
command elements are written in different typefaces.
The actual command and its mandatory options are always printed as command
option. Specifications or parameters that are not required are placed in
[square brackets].
Adjust the settings to your needs. It makes no sense to write ls file(s), if no
file named file(s) actually exists. You can usually combine several parameters,
for example, by writing ls -la instead of ls -l -a.
