True about that
${VAR^^}, didnt thought of that.
The prefixing of CONFFILE with
./ was required to avoid an error message when it was sourced.
@ RudiC
Since i've gotten either the 'full line' or $2-$5 incl quotes and comments, i wanted to remove the both of them.
Now that is already done with your awk/gsub suggestion.
EDIT: The
head was if a variable definition was copied to another line, at some occasions i had 2 output lines.
/solved & improved
Thank you guys

libstdbuf
LIBSTDBUF(3) BSD Library Functions Manual LIBSTDBUF(3)
NAME
libstdbuf -- preloaded library to change standard streams initial buffering
DESCRIPTION
The libstdbuf library is meant to be preloaded with the LD_PRELOAD environment variable to as to change the initial buffering of standard
input, standard output and standard error streams.
Although you may load and configure this library manually, an utility, stdbuf(1), can be used to run a command with the appropriate environ-
ment variables.
ENVIRONMENT
Each stream can be configured independently through the following environment variables (values are defined below):
_STDBUF_I
Initial buffering definition for the standard input stream
_STDBUF_O
Initial buffering definition for the standard output stream
_STDBUF_E
Initial buffering definition for the standard error stream
Each variable may take one of the following values:
"0" unbuffered
"L" line buffered
"B" fully buffered with the default buffer size
size fully buffered with a buffer of size bytes (suffixes 'k', 'M' and 'G' are accepted)
EXAMPLE
In the following example, the stdout stream of the awk(1) command will be fully buffered by default because it does not refer to a terminal.
libstdbuf is used to force it to be line-buffered so vmstat(8)'s output will not stall until the full buffer fills.
# vmstat 1 | LD_PRELOAD=/usr/lib/libstdbuf.so
STDBUF_1=L awk '$2 > 1 || $3 > 1' | cat -n
See also the manpage of stdbuf(1) for a simpler way to do this.
HISTORY
The libstdbuf library first appeared in FreeBSD 8.4.
AUTHORS
The original idea of the libstdbuf command comes from Padraig Brady who implemented it in the GNU coreutils. Jeremie Le Hen implemented it
on FreeBSD.
