I have a file which has multiple record of netstat output, my sample file looks something like the one below. I want to search for PID for ex : 3453, part of the output I also want to see snapshot time, so that I can find whether PID was exist part of particular snapshot or not. Any thoughts?

Expected sample output for search 3453:

With GNU sed:
sed -n '/\*\*\*/,/^$/{ /\*\*\*/p; /3453/p }' file
Output:

I'm running an executable and trying to save terminal output to a file:
# ll

# ./mpx-mini-test | tee -a mpx-mini-test.log
#
# cat mpx-mini-test.log

As you can see, there're some prints in terminal without "| tee -a **.log".
But with "| tee -a **.log", nothing is saved to file.
I suspect it has something to do with the "Abort (core dumped)", did some googling but can't figure out exactly why. Is there anyone knows why? And how could I save all terminal outputs(including the "Abort (core dumped)") to file? Thanks in advance.
Has anyone tried using the bitbake-env utility lately?
I do not see it installed:
[user#localhost build]$ which bitbake
~/YOCTO/oe_core_embedded/poky/bitbake/bin/bitbake
[user#localhost build]$ which bitbake-env
/usr/bin/which: no bitbake-env in (/home/user/YOCTO/oe_core_embedded/poky/scripts:/home/user/YOCTO/oe_core_embedded/poky/bitbake/bin:/usr/libexec/python2-sphinx:/usr/lib64/qt-3.3/bin:/usr/lib64/ccache:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/user/.local/bin:/home/user/bin)
[user#localhost build]$
As well I do not see it in the bitbake command listing:
[user#localhost poky]$ cd bitbake/bin

It still exists/is listed in https://elinux.org/Bitbake_Cheat_Sheet from July 2016.
bitbake-env is a third party utility, and not actually a part of the OpenEmbedded Core hence why you will not see it unless you specifically install it. It is actually an 'improved' version of the bitbake -e flag for bitbake.
bash-4.3$ bitbake --help
Usage: bitbake [options] [recipename/target recipe:do_task ...]
Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
will provide the layer, BBFILES and other configuration information.
Options:
...
-e, --environment Show the global or per-recipe environment complete
with information about where variables were
set/changed.
I have a question about Emacs customisation.
For example, there is a git repo like https://github.com/bbatsov/projectile.

It is suggested that the recommended way to install this feature is using MELPA. I can clone this git repo, but I can not ping MELPA. My question is how can I manually install this Emacs feature? More generic, how can I manually install such a Emacs feature which is using cask?
In your example,you dose not need cask
git clone https://github.com/bbatsov/projectile /some/place/you/want
Then add
(add-to-load-path "/some/place/you/want")
in your .emacs or init.el.Then
(require 'projectile)
manually.
I was googling and found this link helpful https://serverfault.com/questions/538233/qmail-limit-number-of-emails-sent-by-user-or-domain-per-hour
My OS is Centos with Plesk 11.x + Qmail
I tried my best to follow given directives in the link e.g.
1) I installed spamdkye successfully
2) Created mkdir -p /home/vpopmail/bin/qmail-antispam
3) mkdir -p /etc/qmailadmin/qmail-spam/blacklist
4) crontab -e
*/5 * * * * /home/vpopmail/bin/qmail-antispam >> /var/log/maillog 2>&1
5) I saved script as qmail-antispam as well as moved as blacklist but on both positions it displays:
Code:
# tail -f /var/log/maillog | grep "qmail-antispam"
/bin/sh: /home/vpopmail/bin/qmail-antispam: is a directory
/bin/sh: /home/vpopmail/bin/qmail-antispam: is a directory

Questions:
Please advise where:
1) where I save this script either in /etc/qmailadmin/qmail-spam/blacklist or /home/vpopmail/bin/qmail-antispam and with which name?
2) MAX_CORREOS=3000 //is that to set maximum limit??
ID_SERVER="ID_SERVER" //May I change this to my server hostname??
CONTACTO=admin#gmail.com //Here I set admin email to send report. Is that right??
Please advise
Thanks in anticipation
vi /home/vpopmail/bin/qmail-antispam
copy & paste the script provided in Link
Edit script and change following:
MAX_CORREOS=100
ID_SERVER="my server hostname"
CONTACTO=admin#gmail.com
# chown root /home/vpopmail/bin/qmail-antispam
# chmod 755 /home/vpopmail/bin/qmail-antispam
and check its working fine:
# tail -f /var/log/maillog | grep "qmail-antispam"

Linux process link stdin/output/err to /dev/tty, for example:
ls -all /proc/5310/fd show
lrwx------ 1 ubuntu ubuntu 64 Mar 31 09:58 0 -> /dev/pts/1
lrwx------ 1 ubuntu ubuntu 64 Mar 31 09:58 1 -> /dev/pts/1
lrwx------ 1 ubuntu ubuntu 64 Mar 31 09:58 2 -> /dev/pts/1
Which component in system is in charge of the link? How it link the fd 0/1/2 to /dev/pts/1? How can I change it to be /dev/pts/2
