Alias to play flash videos with mplayer. You can replace mplayer with your favorite video player. This alias supports Chrome & Firefox's way of handling the flash plugin. It will play all the videos in the cache. Note that certain videos might never make it to the cache, if the publisher ask for them not to: they will just be loaded in RAM. A variant if you're just interested in playing the audio, for example for a music :
alias flashmusic="mplayer -vo null \$(find /proc/\$(pgrep -f 'libgcfl|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"0alias flashplay="mplayer \$(find /proc/\$(pgrep -f 'libgcflash|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)" -

Very similar as doing "wget http://example.com/mytarball|tar xzv", this one involves the "tee" command between both, which will simultaneously write the tarball and copy it to stdout. So this command will locally save the tarball and extract it - both at the same time while it downloads.
0wget -O- http://example.com/mytarball.tgz | tee mytarball.tgz | tar xzv -
alias h="history | awk '{\$1=\"\";print substr(\$0,2)}'" # h [ 07/07/2013 10:04:53 ] alias h="history | awk '{\$1=\"\";print substr(\$0,2)}'"
0history | awk '{$1="";print substr($0,2)}' -
this is even shorter
0curl ifconfig.me -
