I like Dennis Ritchie. Talk to the machine:

Primary language:

Again, Forgot it?

tcpdump -i eth0 port 80
tcpdump -i eth0 port 80 -w dump.pcap
tcpdump -i eth0 port 80 -l | tee dump.pcap


grep whatever myfile | tee /dev/tty | wc -l

$ git reset --hard HEAD; 
  git clean -f -d ; 
  git pull; # force pull

$ grep -A 1 -B 1:
A (after)
B (before)
C (context [before + after])

$ tcpflow -i any -C -e port 1234  # As root, listen packets in a port

$ freeze > recover

alt + print screen + k
alt + print screen + re is ub

$ echo -e '#!/bin/bash\nsleep 50\nexport DISPLAY=:0.0\nxset s off\nxset -dpms' > /var/tmp/pp.sh; cat /var/tmp/pp.sh;

#!/bin/bash
sleep 50
export DISPLAY=:0.0
xset s off
xset -dpms

eth0 and eth1 - in and out traffic

$ ip rule add from 10.0.0.108/32 table 1
$ ip route add default via 10.0.0.1 dev eth0 table 1
$ ip rule add from 10.0.0.28/32 table 2
$ ip route add default via 10.0.0.1 dev eth1 table 2

except ssh other traffic from that source

$ tcpdump -vv src 54.2.2.1 and not dst port 22

Normal termination

killall -SIGHUP firefox
killall -SIGINT firefox

Non gracefull termination

killall -SIGKILL firefox

Qemu:

qemu-system-x86_64 -enable-kvm -m 256 -usb /dev/sdc

qemu-system-x86_64 -cdrom filename.iso

qemu-system-x86_64 -hda /dev/sdx

Gst:

wget http://gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-0.10.23.tar.gz
tar xvfz gst-plugins-bad
./autogen.sh
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libexecdir=/usr/lib --with-package-name="GStreamer Bad" --with-package-origin="http://www.ubuntu.org/" --enable-gtk-doc --disable-static;
make
make install

Ffmpeg:

ffmpeg -i /home/sun/Desktop/Default\ Project.mpeg -b:v 300k -ar 8000 -ac 1 -s qcif -r 5 /home/sun/Desktop/pingpong.3gp # Mobile videos for small size:
