1. ดู Port ที่เปิด
netstat -lntu
as replied by @askmish will give you list of services running on your system on tcp and udp ports where
-l= only services which are listening on some port-n= show port number, don't try to resolve the service name-t= tcp ports-u= udp ports-p= name of the program
A list of just unique port numbers and only IPv4:
netstat -tuwanp4 | awk '{print $4}' | grep ':' | cut -d ":" -f 2 | sort | uniq2. ดู Program ที่ติดตั้ง
How to list all installed packages?
To get a list of packages installed locally do this in your terminal:dpkg --get-selections | grep -v deinstall
(The
-v tag "inverts" grep to return non-matching lines)
To get a list of a specific package installed:
dpkg --get-selections | grep postgres
To save that list to a text file called
packages on your desktop do this in your terminal:dpkg --get-selections | grep -v deinstall > ~/Desktop/packages
Alternatively, simply use
dpkg -l
To get just the packages which were expressly installed (not just installed as dependencies), you can run
aptitude search '~i!~M'
This will also include a brief description, which you may want. If not, use the option
-F '%p',
-------------------------------
Create a backup of what packages are currently installed:
dpkg --get-selections > list.txt
Then (on another system) restore installations from that list:
dpkg --clear-selections
sudo dpkg --set-selections < list.txt
To get rid of stale packages
sudo apt-get autoremove
To get installed like at backup time (i.e. to install packages set by dpkg --set-selections)
sudo apt-get dselect-upgrade
To list all packages intentionally installed (not as dependencies) by apt commands, run the following :
( zcat $( ls -tr /var/log/apt/history.log*.gz ) ; cat /var/log/apt/history.log ) | egrep '^(Start-Date:|Commandline:)' | grep -v aptdaemon | egrep '^Commandline:'
This provides a reverse time based view, with older commands listed first:
Commandline: apt-get install k3b
Commandline: apt-get install jhead
Installation data also showing synaptic usage, but without details (the same with installation date) :
( zcat $( ls -tr /var/log/apt/history.log*.gz ) ; \
cat /var/log/apt/history.log ) | egrep '^(Start-Date:|Commandline:)' | grep -v aptdaemon | egrep -B1 '^Commandline:'
providing the following:
Start-Date: 2012-09-23 14:02:14
Commandline: apt-get install gparted
Start-Date: 2012-09-23 15:02:51
Commandline: apt-get install sysstatapt-mark showmanual
man pages state:
will print a list of manually installed packages
So, it should just give a list of explicitly installed packages (though this includes packages that were part of the default initial install) without all of the dependencies included due to these packages being installed.
