Today, I use Ubuntu in Tokyo donut,Yangon. I try to update but I can't.It connect to 192.168.0.254. This IP is proxy in SkyWorld cyberber cafe. I also change setting in Network Proxy and Apply System-Wide. But not work. I can use Internet from firefox but not work in terminal. So, I search in google and I try this comment in terminal

$ echo $http_proxy
192.168.0.254:8080

I print the http_proxy environment in terminal.It show IP. So I fixed like that

$ http_proxy=''
$ echo $http_proxy

And then I tryagain.It's work. I can update and install package from terminal again.

rm -fr ~/.bash_history

ln -s /dev/null ~/.bash_history

Your history will be available in ram for each bash session, but will be gone once you log out.¹

ကြ်န္ေတာ္တို႔ေတြအေနနဲ့ windows Vista မွာဆို shift+ right click လုပ္လိုက္ရံုနဲ့ command prompt here ဆိုျပီးေပၚလာတယ္။ XP မွာဆိုရင္ေတာ့ ဒီမွာ ဖတ္ျပီး လုပ္လိုက္ရင္ ေပၚလာတယ္ဗ်။ အဲ... Ubuntu မွာ မရလို႔ စိတ္ညစ္ေနလား။ ရပါတယ္ဗ်ာ။ ကြ်န္ေတာ္ သံုးေနတာေတာ့ ၾကာျပီ။ ေျပာျပဖို႔ေမ့ေနလို႔ဗ်။ ကြ်န္ေတာ္က ဒါေလးသြင္းလိုက္တယ္ေလ။.

$sudo aptitude install nautilus-open-terminal

အဲဒါဆို အရမ္းအဆင္ေျပတယ္ဗ်။ cd , cd ေတြနဲ့ အဆင့္ဆင့္ သြားေနစရာမလိုဘူးေလ။ ေတာ္ေတာ္ေလးကို အဆင္ေျပျပီး Ubuntu ကို သံုးရတာ ပိုေကာင္းလာတယ္။
