Subject: [buug] To dump core for sure
Hi,
I'm new in this list but I'm almost desperate, so let me ask a
question.
I'm developping multi-threaded application on RedHat Linux 7.2.
The application still contains some bugs and sometimes abort by
SIGSEGV, but it doesn't dump core everytime.
Funny thing is that it sometime does.
It seems like dumping might be controlled by something
environmental, not by application.
So, what I want to know is:
1. Is there some way to force applications to dump core?
(Like, calling some function in the source? if any...)
2. What would be the case that application don't dump ocre
even if it's SIGSEGV?
I checked taht limit is set to "unlimited".
Please tell me if someone knows the answer.
Thank you for your help, in advance.
Regards,
Masahide Tomita

Ha all,
I want to grab data from either side of a matched criteria from grep.
Any one got any other ideas of a command and if it does work please tell
me what OS and version and what shell. Also if anyone does do this how
do you just get lines below or lines above the match rather than both.
This is what I am trying to do
Inputfile

Grep -2 'D' inputfile

GNU grep has some options that seem do what you want:
$ grep --help
[...]
Context control:
-B, --before-context=NUM print NUM lines of leading context
-A, --after-context=NUM print NUM lines of trailing context
-C, --context=NUM print NUM lines of output context
-NUM same as --context=NUM
[...]
$ grep -2 D testfile
B
C
D
E
F
--
B
C
D
E
F
$ grep --version
grep (GNU grep) 2.5.1
[...]

I am not good, but I think you can do this. YOu can do it with grep.
grep D -v, this will give you the another result set. YOu can try this
ls -la | grep d -v
You will get the list of file, except the directories.
