You can also use the
man command to print/save
manpages' commands to a PDF file:
Code:
man t- ls | ps2pdf - ls.pdf
This will save the contents of
man ls to a PDF file in your home directory. Another command you can use is
apropos followed by a keyword
, i.e.
you'll get a list of tools that can handle tasks related to the keyword "network" such as this
Code:
$ apropos network
interfaces (5) - network interface configuration for ifup and ifdown
aseqnet (1) - ALSA sequencer connectors over network
atmel_fwl (8) - Load firmware into Atmel at76c50x wireless networking chips.
byteorder (3) - convert values between host and network byte order
ctstat (8) - unified linux network statistics
dhclient-script (8) - DHCP client network configuration script
endhostent (3) - get network host entry
endnetent (3) - get network entry
endnetgrent (3) - handle network group entries
ethtool (8) - query or control network driver and hardware settings
freeaddrinfo (3) - network address and service translation
freehostent (3) - get network hostnames and addresses
gai_cancel (3) - asynchronous network address and service translation
The numbers in parenthesis indicates which
manpage contains information about the tool, thus for
interfaces (5) you'd do:
Code:
$man -t 5 interfaces | ps2pdf - interfaces.pdf
Another command is
help which will show you a list of bash's built-in commands with a short description
. (Please, note that my system is in Spanish, and while I did translate a few lines there were too many, in any case, those are really meaningless for now, you'll know their meaning when you see them in your system, with your own language.
)
Code:
$ help
GNU bash, versión 5.1.4(1)-release (x86_64-pc-linux-gnu)
These shell commands are defined internally. Type `help 'to
see this list.
Type `help name 'to learn more about the function` name'.
Use `info bash 'to learn more about the shell in general.
Use `man -k 'or` info' to learn more about the commands that are not in
this list.
An asterisk (*) next to a name means that the command is disabled.
