Linux Hidden display terminal cursor

First, use the Shell's echo command to implement.

Echo-ne <ctrl+v><ESC>[?25l&<60;&<60;&<60; Hide Cursor

Echo-ne <ctrl+v><ESC>[?25h&<60; Display cursor

L,h is the letter, <ctrl+v> the CTRL key is pressed, then V is pressed, <ESC> is the ESC key on the keyboard

In the terminal echo scenario is as follows:

echo-ne&<60; ^[[?25l

echo-ne&<60; ^[[?25h

Where ^[is obtained with <ctrl+v><ESC>, the direct input ^[is invalid

The cursor in HyperTerminal often disappears unexpectedly, which is a good way to get it back.

A simpler approach

Echo-e "\033[?25l" Hide cursor

Echo-e "\033[?25h" Display cursor

In fact \033 (octal, equivalent to 10 binary 27) is the value of the character entered by <ctrl+v><ESC>.

Echo-ne "\33[32m" To change the display color of a character to green

Echo-ne "\33[3;1h" to move the cursor to the 1th column of line 3rd

Some of the specific excerpts are as follows:

\33[0m Close All Properties

\33[1m Setting High brightness

\33[4m Underline

\33[5m Flashing

\33[7M Reverse Display

\33[8m blanking

\33[30m--\33[37m setting foreground color

\33[40m--\33[47m Set background color

\33[na the cursor to move n rows

\33[NB cursor down n rows

\33[NC cursor right shifts n rows

\33[nd cursor left n rows

\33[Y;XH Setting the cursor position

\33[2J Clear Screen

\33[k clears the contents from the cursor to the end of the line

\33[s Save Cursor position

\33[u Restore cursor Position

\33[?25l Hide Cursor

\33[?25h Display cursor

Word background color range: 49----

40: Black

41: Crimson

42: Green

43: Yellow

44: Blue

45: Purple

46: Dark Green

47: White

Word color: 39-----------

30: Black

31: Red

32: Green

33: Yellow

34: Blue

35: Purple

36: Dark Green

37: White

Don't forget the-E and "", otherwise it won't work.

Second, using the printf function of Linux C to implement

printf ("\033[?25h");//Display cursor

printf ("\033[?25l");//Hide cursor
