I am using the while-loop to read a file.
The file has lines with null-terminated strings (words, actually.)
What I have by that reading - just a first word up to '\0'!
I need to have whole string up to 'new line' - (LF, 10#10, 16#A)
What I am doing wrong?

...when the lines use both a colon and commas to separate the parts you want read as information.
The first version of this script used cut and other non-Bash-builtins, frequently, which made it nice and zippy with little more than average processor load in GNOME Terminal but, predictably, slow... (2 Replies)
Hello everybody,
I'm still slowly treading my way into bash scripting (without any prior programming experience) and hence my code is mostly what some might call "creative" if they meant well :D
I have created a script that serves its purpose but it does so very slowly, since it needs to work... (4 Replies)

The typewriter-part is a 'bonus' but still has its own flaws, but thats for later.
So in some way, i'm trying to rewrite cat using bash and other commands.
But sadly it fails on... (2 Replies)

So while i'm trying to increase security/usability of my TUI commands, i'm currently at tui-conf-get.
There was also a bug, i wanted to fix, but sadly that bugfix is more insecure - but twice as fast as my current buggy method.

I'm new to Linux (Ubuntu 16.04), and very new to BASH scripting. I have a Numato 8-channel USB GPIO device, which is a DAQ that appears in the system as a serial port. In Linux it appears as ttyACM0. I can easily manipulate a GPO with, for example:

MAN(7) Miscellaneous Information Manual MAN(7)NAME
man - macros to typeset manual
SYNOPSIS
nroff -man file ...
troff -man file ...
DESCRIPTION
These macros are used to lay out pages of this manual. A skeleton page may be found in the file /usr/man/man.template.
Any text argument t may be zero to six words. Quotes may be used to include blanks in a `word'. If text is empty, special treatment is
applied to the next input line with text to be printed. In this way .I may be used to italicize a whole line, or .SM may be followed by .B
to make small bold letters.
A prevailing indent distance is remembered between successive indented paragraphs, and is reset to default value upon reaching a non-
indented paragraph. Default units for indents i are ens.
Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.
These strings are predefined by -man:
*R `(Reg)', trademark symbol in troff.
*S Change to default type size.
FILES
/usr/share/tmac/tmac.an
/usr/man/man.template
