Bash Shell Keyboard Shortcuts For Linux Users :

The default shell on most Linux operating systems is called Bash. There are a couple of important hotkeys that you should get familiar with if you plan to spend a lot of time at the command line. These shortcuts will save you a ton of time if you learn them.
Some Most Common and useful Linux shortcuts:

Tabulator Shortcut - one of the most important keys:

Tabulator is used to complete commands and filenames. The button is found on the left side of the keyboard
If your current working folder (check with pwd) contains the folder Documents (check with ls) and you want to change into it (with cd) you can type:

cd Doc<tab>
This will complete the folder name and leave you with the command
cd Documents
If there are more than one folder beginning with Doc pressing tab will complete the first folder, sorted alphabetic. You can get all alternatives beginning with Doc by pressing tab a second time.
Tabulator Shortcut for Linux Commands :
Tabulator work the same way with commands, but commands are not completed by the first tabulator press if there are more than one alternative. By typing gnome<tab><tab> you will get a list of all commands beginning with gnome.
Complete list of Tricks for Press TAB twice.
Here "2T" means Press TAB twice :
  • 2T : All available commands(common)
  • (string) 2T : All available commands starting with (string)
  • /2T : Entire directory structure including Hidden one
  • 2T : Only Sub directory inside including Hidden one
  • *2T : Only Sub Dirs inside without Hidden one
  • ~2T : All Present Users on system from "/etc/passwd"
  • $2T : All Sys variables
  • @2T : Entries from "/etc/hosts"
  • =2T : Output like ls or dir

Linux Shortcuts for Shell Commands :

Most Common Shortcuts:
  • Ctrl + D : exit a terminal, same as typing `exit`
  • Ctrl + L : clears the screen, same as `clear`
  • Ctrl + C : breaks/cancels an ongoing operation
  • Ctrl + Z : pauses (stops) an ongoing operation. Type `fg` (foreground) to resume it or `bg` (background) to continue the process in the background
  • Ctrl + Alt + Del : shuts down computer
Other bash Shell shortcuts:
Bash Shell shortcuts for Moving backward Forward :
  • Ctrl + A : Go to the beginning of the line you are currently typing on
  • Ctrl + E : Go to the end of the line you are currently typing on
  • Ctrl + U : Clears the line before the cursor position. If you are at the end of the line, clears the entire line.
  • Ctrl + W : Delete the word before the cursor.
  • Ctrl + K : Clear the line after the cursor.
  • Ctrl + T : Swap the last two characters before the cursor.
  • Esc + T : Swap the last two words before the cursor.
  • Alt + F : Move cursor forward one word on the current line.
  • Alt + B : Move cursor backward one word on the current line.
History related bash shell shortcuts:
  • Ctrl + R : Let’s you search through previously used commands.
  • Alt + < : Move to the first line in the history.
  • Alt + > : Move to the last line in the history.
Other bash shell shortcuts:
  • Ctrl + H : Same as backspace.
  • Tab : Auto:complete files and folder names.
  • Ctrl + Y : to paste it (as in delete and copy) all text in front of the cursor.
  • Alt + ? : Show current completion list.
  • Alt + * : Insert all possible completions.
  • Alt + / : Attempt to complete filename.
  • Alt + c : Capitalize the word.
  • Alt + l : Make word lowercase.
  • Alt + r : Recall command.
Note : Some of these commands may not work if you are accessing bash through a telnet ,ssh session, or depending on how you have your keys mapped.

Linux GUI - KDE Shortcuts:

Most common Linux Shortcuts for KDE :
  • Ctrl + Esc : KDE System Guard process table.
  • Alt + F1 : K-Menu popup.
  • Alt + F2 : Run command.
  • Alt + F3 : Application control.
  • Alt + F4 : Terminated active application.
  • Alt + F5 : Quick application switcher.
  • Alt + Tab : Switch between active applications.
  • Ctrl + Alt + Shift + PageDN : direct shutdown.
  • Ctrl + Alt + Shift + PageUP : direct reboot.

Linux Shortcuts for Virtual terminals:

Most common Linux Shortcuts for Virtual terminals :
  • Ctrl + Alt + F1 : Switch to the first virtual terminal. In Linux, you can have several virtual terminals at the same time. The default is 6.
  • Ctrl + Alt + Fn : Switch to the nth virtual terminal. Because the number of virtual terminals is 6 by default, n = 1...6.
  • tty : Typing the tty command tells you what virtual terminal you're currently working in.
  • Ctrl + Alt + F7 : Switch to the GUI. If you have X Window System running, it runs in the seventh virtual terminal by default. If X isn't running, this terminal is empty.

Miscellaneous Linux Shortcuts :

Most common miscellaneous Linux Shortcuts :
  • ALT+Ctrl+(F1-F7): To switch between different terminals..or if GUI is installed then to switch between GUI and text mode.
GUI specific:
  • Ctrl+Q : Mostly to quit from and application(like gimp, konqueror ).
Switch Desktop:
  • Desktop 1 : Ctrl +F1
  • Desktop 2 : Ctrl +F2
  • Desktop 3 : Ctrl +F3
  • Desktop 4 : Ctrl +F4
Scroll Lock :
  • Press Scroll Lock : locks terminal input/output - allows to read console contents when output is going too fast. To unlock, press Scroll Lock once again.

IPv4 subnetting reference

From Wikipedia, the free encyclopedia


In the IPv4 address space certain address blocks are specially allocated or reserved for special uses such as loopback interfaces, private networks (RFC 1918),[1] and state-less autoconfiguration (Zeroconf, RFC 3927)[2] of interfaces. Such addresses may be used without registration or allocation from Regional Internet Registries (RIRs). However, these address ranges must not be routed into the public Internet infrastructure.
The netmask is a bitmask that can be used to separate the bits of the network identifier from the bits of the host identifier. It is often written in the same notation used to denote IP addresses.
Not all sizes of prefix announcement may be routable on the public Internet: see routing, peering.
Class Leading bits Start End Default Subnet Mask in dotted decimal CIDR notation
A 0 0.0.0.0 127.255.255.255 255.0.0.0 /8
B 10 128.0.0.0 191.255.255.255 255.255.0.0 /16
C 110 192.0.0.0 223.255.255.255 255.255.255.0 /24
D 1110 224.0.0.0 239.255.255.255 not defined not defined
E 1111 240.0.0.0 255.255.255.254 not defined not defined
The blocks numerically at the start and end of classes A, B and C were originally reserved for special addressing or future features, i.e., 0.0.0.0/8 and 127.0.0.0/8 are reserved in former class A; 128.0.0.0/16 and 191.255.0.0/16 were reserved in former class B but are now available for assignment; 192.0.0.0/24 and 223.255.255.0/24 are reserved in former class C.
While the 127.0.0.0/8 network is a Class A network, it is designated for loopback and cannot be assigned to a network.
See (RFC 5735 Special Use IPv4 Addresses)[3]
CIDR host bits Netmask Available Adresses (-2 = number of hosts) Classful name Typical usage
/8 24 255.0.0.0 16777216 = 224 Class A (see this list) Largest block allocation made by IANA

/32 0 255.255.255.255 1 = 20
Host route
In common usage, the "host all zeros" address is reserved for referring to the entire network, while the "host all ones" address is used as a broadcast address in the given subnet; this reduces the number of addresses available for hosts by 2. This explains the reference to /31 networks as "Rarely Used," as the only possible addresses on a /31 network are "host all ones" and "host all zeros." RFC 3021 creates an exception to the "host all ones" and "host all zeros" broadcast usage to make /31 networks usable for point-to-point links. In practice, however, point-to-point links are still typically implemented using /30 networks, or occasionally by /32 and point-to-point explicit host routes.[citation needed] There is generally no technical advantage to /31 versus /32, although one or the other may be more convenient based on other issues. A /30 is always wasteful and has as its sole advantage that it behaves "as expected" for any other subnetwork.
