In addition to what has already been said, CODE tags use a fixed width font. So text like:
iiiiiiiiii
WWWWWWWWWW
which looks like very different line lengths without CODE tags, clearly show that they contain the same number of characters when that same text is displayed using CODE tags:
And, if your code or data contains tab characters, those tabs are preserved if you copy and paste text from regions of a post that are tagged by CODE or ICODE tags, but copy as spaces when not tagged.
So, yes: always use code tags for full line sample code, input, and output; and use icode tags for partial line, imbedded sample code, input, and output!
I'm a Unix newbie.
In a shell-script, is there any way to accept keyboard input (via STDIN) without having it display on the screen? I know keying in a login password sort of does this by replacing what you key with astericks (*) but I believe that's a "C" routine. I'd like to be able to... (2 Replies)
How can I write to another user's pseudo tty, but not to its current prompt position (as in open("/dev/pts007", ...) followed by write() ). Instead I would like to write to the top center of the screen using color red, for example. Like curses, but from another console. (6 Replies)

The keyboard input is being caught by 'read' command.

Hello, everyone.
Could someone, please, tell me how to get the number of bytes in the terminal input queue without blocking and without consuming these bytes? I guess it could be called the peek functionality.

tty
tty(1) User Commands tty(1)NAME
tty - return user's terminal name
SYNOPSIS
tty [-l] [-s]
DESCRIPTION
The tty utility writes to the standard output the name of the terminal that is open as standard input. The name that is used is equivalent
to the string that would be returned by the ttyname(3C) function.
OPTIONS
The following options are supported:
-l Prints the synchronous line number to which the user's terminal is connected, if it is on an active synchronous line.
-s Inhibits printing of the terminal path name, allowing one to test just the exit status.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of tty: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Standard input is a terminal.
1 Standard input is not a terminal.
>1 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
|CSI |Enabled |

|Standard |standards(5). |
+-----------------------------+-----------------------------+
SEE ALSO isatty(3C), ttyname(3C), attributes(5), environ(5), standards(5)DIAGNOSTICS
not on an active synchronous line
The standard input is not a synchronous terminal and -l is specified.
not a tty
The standard input is not a terminal and -s is not specified.
NOTES
The -s option is useful only if the exit status is wanted. It does not rely on the ability to form a valid path name. Portable applications
should use test -t.
