stty command:
stty is an important command for setting and reporting terminal I/O options.
stty, used by itself, lists many of the most important terminal communication parameters:
$stty -> It displays
speed 9600 baud; -parity hupcl
rows = 25; columns = 80; ypixels = 281; xpixels = 486;
erase = ^h; swtch = <undef>; rprnt = <undef>; flush = <undef>; werase = <undef>; lnext = <undef>;
-inpck -istrip icrnl -ixany onlcr tab3
echo echoe echok
Used with the -a option, stty lists all of the terminal/keyboard settings.
$stty -a -> It displays
speed 9600 baud;
rows = 25; columns = 80; ypixels = 281; xpixels = 486;
intr = DEL; quit = ^|; erase = ^h; kill = @;
eof = ^d; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^q; stop = ^s; susp = ^z; dsusp = ^y;
rprnt = <undef>; flush = <undef>; werase = <undef>; lnext = <undef>;

The following commands set your command-line erase character, your end-of-file character, interrupt character, and suspension character. These options are often set in your startup files, which are discussed in the next sections.
$stty erase ^h -> Set your erase character to ^h. This is usually your Backspace key.
$stty eof ^d -> Set your end-of-file character to ^d.
$stty intr ^c -> Set your interrupt character to ^c. This lets you stop processes that are actively running in the foreground on your computer.
$stty susp ^z -> Set your suspend character to ^z. This lets you suspend processes that are currently running in the foreground.
