Linux Shell hotkey

• Ctl-A

  Moves cursor to beginning of line of text
  (on the command-line).

• Ctl-B

  Backspace
  (nondestructive).

• Ctl-C

  Break.
  Terminate a foreground job.

• Ctl-D

  Log out from a shell (similar to
  exit).

  EOF (end-of-file). This also
  terminates input from stdin.

  When typing text on the console or in an
  xterm window,
  Ctl-D erases the character under the
  cursor. When there are no characters present,
  Ctl-D logs out of the session, as
  expected. In an xterm window,
  this has the effect of closing the window.

• Ctl-E

  Moves cursor to end of line of text
  (on the command-line).

• Ctl-F

  Moves cursor forward one character position
  (on the command-line).

• Ctl-G

  BEL. On some
  old-time teletype terminals, this would actually ring
  a bell. In an xterm it might
  beep.

• Ctl-H

  Rubout (destructive backspace).
  Erases characters the cursor backs over while
  backspacing





• Ctl-I

  Horizontal tab.

• Ctl-J

  Newline (line feed).
  In a script, may also be expressed in octal notation --
  '\012' or in hexadecimal -- '\x0a'.

• Ctl-K

  Vertical tab.

  When typing text on the console or in an
  xterm window,
  Ctl-K erases from the character
  under the cursor to end of line. Within a script,
  Ctl-K may behave differently,
  as in Lee Lee Maschmeyer's example, below.

• Ctl-L

  Formfeed (clear the terminal
  screen). In a terminal, this has the same effect as the
  clear command. When sent
  to a printer, a Ctl-L causes
  an advance to end of the paper sheet.

• Ctl-M

  Carriage return.







• Ctl-N

  Erases a line of text recalled from
  history buffer
  [6] (on the
  command-line).

• Ctl-O

  Issues a newline
  (on the command-line).

• Ctl-P

  Recalls last command from history
  buffer (on the command-line).

• Ctl-Q

  Resume (XON).

  This resumes stdin in a terminal.

• Ctl-R

  Backwards search for text in history
  buffer
  
  (on the command-line).

• Ctl-S

  Suspend (XOFF).

  This freezes stdin in a terminal.
  (Use Ctl-Q to restore input.)

• Ctl-T

  Reverses the position of the character the cursor
  is on with the previous character (on the
  command-line).

• Ctl-U

  Erase a line of input, from the cursor backward to
  beginning of line. In some settings,
  Ctl-U erases the entire
  line of input, regardless of cursor
  position.

• Ctl-V

  When inputting text, Ctl-V
  
  permits inserting control characters. For example, the
  following two are equivalent:
  

  echo -e '\x0a' echo <Ctl-V><Ctl-J>

  Ctl-V is primarily useful from
  within a text editor.

• Ctl-W

  When typing text on the console or in an xterm window,
  Ctl-W erases from the character
  under the cursor backwards to the first instance of
  whitespace. In some settings, Ctl-W
  erases backwards to first non-alphanumeric character.

• Ctl-X

  In certain word processing programs,
  Cuts highlighted text
  and copies to clipboard.

• Ctl-Y

  Pastes back text previously
  erased (with Ctl-K or
  Ctl-U).

• Ctl-Z

  Pauses a foreground job.

  Substitute operation in certain
  word processing applications.

  EOF (end-of-file) character
  in the MSDOS filesystem.
