Once upon a time, we want to find a files that just containing particular text. Unfortunately, we have 10000 files inside our folder. Should we check one by one? yes, you should. Until you find a better way to solve this issue :). For me, it was happened when I stored my configuration files into one folder, there are about 50+ files and I just want to know where are my files that I need. I do not want to ruined my time with opening files one by one. After a little googling, I found a better way to solve this. You can just using :
Currently I am using Linux Mint 14 and Lubuntu 12.10, as we know, both of them using ubuntu as ancestor. I do not know this problem would raised if we using other linux distribution or no. I do not know what I had to do before, because I guess the problem is on the OS (silly guess, haha). but with a little surfing with my friend, I know the solution is quite simple. We just have to install these package from repository :
$ sudo apt-get install network-manager-pptp-gnome
for some vpn, they need (note : for me, above installation is enough)
$sudo apt-get install network-manager-openvpn-gnome
$sudo apt-get install network-manager-openvpn
Do you ever face a trouble when you want to look directory tree structure in linux? I do :). I look my friends just write command “tree” in his computer, then directory structure will be shown. But it is not work on my computer! after a little searching with my besties, finally I found a way out. this is simple, very simple. you just have to install app that called “tree” to use this command. how do I know? because when you type “tree”, it was show me like not found tree command.
