hi, i've searched the forums' entries and have tried some of the examples -- to no avial -- this is my first post -- thanks in advance for your help...
As part of an installation program -- i'm receiving two(2) extraneous "libcxb WARNING!" statements -- i want to use sed to eliminate the appearance of these warnings...
The warnings appear as follows:
libxcb: WARNING! Program tries to unlock a connection without having acquired
a lock first, which indicates a programming error.
There will be no further warnings about this issue.
libxcb: WARNING! Program tries to lock an already locked connection,
which indicates a programming error.
There will be no further warnings about this issue.
Note, the warnings appear to be formatted in such a way that the 2nd & 3rd lines in each warning always appear in the same position. Nevertheless, I want to eliminate the entire warning, i.e., everything from libxcb: to ...about this issue.
Could some please help... thx very much!
installscript.sh | sed '/^libxcb/,/this issue\.$/d'
That will block the error message. Chances are your message is not extraneous, unless there is a problem with libxcb code.
Thanks Jim,
unfortunately, with the changes in place, i still see both 'libxcb:' warnings... the syntax is as you prescribed
installScript.sh | sed '/^libxcb/,/this issue\.$/d'
did i miss something... please let me know & thx!
If that output is going to stderr instead of stdout try:
installscript.sh &2>1 | sed '/^libxcb/,/this issue\.$/d'
Thanks Jim, there's some progress -- however the 'libxcb' warning have just moved further down -- i.e., the install progress further before the warnings appear... any ideas...?

Thanks ghost... i applied your suggestion, but the warnings continue to appear -- I understand these underlying errors are somewhat well-known(notorious) JRE issues... that many folks have chosen to ignore -- i just want to 'mask' them from my users so I can avoid questions... etc
So, I appreciate very much the insights -- and hopefully your continued help -- if there's anyway to mask these -- I'd really appreciate finding a solution.
it works for me

i'm applying your suggestion to the output of < ${PATH_TO_APPS}/*.bin >
${PATH_TO_APPS}/*.bin | awk '/this issue/{f=0;next}/^libxcb/{f=1}f{next}f==0'
the output continues to show:

i need the 'awk' expression to take the output of <
${PATH_TO_APPS}/*.bin > and eliminate the warnings... what am i missing...?
then change /^libxb/ to /^libxb|awk/
thanks ghost -- i appreciate your guidance --
i changed
${PATH_TO_APPS}/*.bin | awk '/this issue/{f=0;next}/^libxcb/{f=1}f{next}f==0'
to
${PATH_TO_APPS}/*.bin | awk '/this issue/{f=0;next}/^libxcb|awk/{f=1}f{next}f==0'
i still see the WARNINGS appearing -- no change in the output...
please help --

it works ok for me.

thanks ghost,
just so we're on the same page, i'm trying to run this as part of an script that calls a .bin from someplace defined in {PATH_TO_APPS} -- the warnings are thrown when the JRE gets unpacked --
as i noted in one of my previous posts -- these JRE warnings are well-known and I just want to mask them from customers
is there any issue with what i've described that would prevent the awk expressions we've tried from operating correctly -- what are some other explanations...?
please stay with me -- i need to get this working...
