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)
I am developing a script that will run with '/bin/ksh' shell.
The script is intended to receive a password by keyboard input, but for security reasons I would like to hide what the user is typing.
The keyboard input is being caught by 'read' command.
exmaple :
echo "Please type your new... (1 Reply)

For example :

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.

Hello All,
I have a text file containing output from a command that contains lots of escape/control characters that when viewed using vi or view, looks like jibberish. But when viewed using the cat command the output is formatted properly.
Is there any way to take the output from the cat... (7 Replies)

fmt
FMT(1) BSD General Commands Manual FMT(1)NAME
fmt -- simple text formatter
SYNOPSIS
fmt [-cmnps] [-d chars] [-l num] [-t num] [goal [maximum] | -width | -w width] [file ...]
DESCRIPTION
The fmt utility is a simple text formatter which reads the concatenation of input files (or standard input if none are given) and produces on
standard output a version of its input with lines as close to the goal length as possible without exceeding the maximum. The goal length
defaults to 65 and the maximum to 10 more than the goal length. Alternatively, a single width parameter can be specified either by prepend-
ing a hyphen to it or by using -w. For example, ``fmt -w 72'', ``fmt -72'', and ``fmt 72 72'' all produce identical output. The spacing at
the beginning of the input lines is preserved in the output, as are blank lines and interword spacing. Lines are joined or split only at
white space; that is, words are never joined or hyphenated.
The options are as follows:
-c Center the text, line by line. In this case, most of the other options are ignored; no splitting or joining of lines is done.
-m Try to format mail header lines contained in the input sensibly.
-n Format lines beginning with a '.' (dot) character. Normally, fmt does not fill these lines, for compatibility with nroff(1).
-p Allow indented paragraphs. Without the -p flag, any change in the amount of whitespace at the start of a line results in a new para-
graph being begun.
-s Collapse whitespace inside lines, so that multiple whitespace characters are turned into a single space. (Or, at the end of a sen-
tence, a double space.)
-d chars
Treat the chars (and no others) as sentence-ending characters. By default the sentence-ending characters are full stop ('.'), ques-
tion mark ('?') and exclamation mark ('!'). Remember that some characters may need to be escaped to protect them from your shell.
-l number
Replace multiple spaces with tabs at the start of each output line, if possible. Each number spaces will be replaced with one tab.
The default is 8. If number is 0, spaces are preserved.
-t number
Assume that the input files' tabs assume number spaces per tab stop. The default is 8.
The fmt utility is meant to format mail messages prior to sending, but may also be useful for other simple tasks. For instance, within vis-
ual mode of the ex(1) editor (e.g., vi(1)) the command
!}fmt
will reformat a paragraph, evening the lines.
SEE ALSO mail(1), nroff(1)HISTORY
The fmt command appeared in 3BSD.
The version described herein is a complete rewrite and appeared in FreeBSD 4.4.

BUGS
The program was designed to be simple and fast - for more complex operations, the standard text processors are likely to be more appropriate.
When the first line of an indented paragraph is very long (more than about twice the goal length), the indentation in the output can be
wrong.
The fmt utility is not infallible in guessing what lines are mail headers and what lines are not.
