I made a directory in my ubunto desktop and copied some file inside it.
I tried to go inside the directory by using the terminal.
the issue I have is when I want to back to the parent directory which is "Desktop" by using "cd.." command I got an error says cd..: command not found
I'm a newbie and want to know the reason.
would you explain it for me.
thank you
You need space, after command cd
cd ..
You missed the space in between cd and ..:
cd ..
You are missing a space, should be cd ..

If this question is not considered to have this place in this forum, tell me I will remove it instantly !
I have installed on my ubuntu a vim plugin (called NERDTree). It works well when I open a file with a non-root status. When I run vim as a root and I try to launch the plugin with :NERDTree, I am told the command 'NERDTree' is unknown. Someone could help ?
Plugins placed in /usr/share/vim/vim7x will most likely be overwritten at the next upgrade. If you want your plugins to be available to root you should install them in /root/.vim.
That said, Vim comes by default with a file explorer plugin called netrw. You may try to learn how to use it (:h netrw) before installing any third party replacement.
Did you install the NERDTree plugin in your home ~/.vim/plugins directory? If so, then the root user probably doesn't "see" it. Move it to the global plugins directory and that should fix it.

I need to put a startup script to my CentOS6 server.
I see that I need a script that contains start-stop cases.
But I have a problem to make it and neither how to put this script to startup.
Anyone can say me how can I add it?
The script must run a simply command that run a jar file:
java -jar FileName.jar
The simplest way would be to add your command to the file
/etc/rc.d/rc.local
Commands in the above file are run at startup (as root). Note that if you do this, your command will NOT respond to the usual service start/ stop commands.

On installing yuidoc I'm getting the following warning.
npm WARN package.json connect#1.9.2 No README.md file found!
When trying to start yuidoc --server later it shows me:
info: (yuidoc): Scanning for yuidoc.json file.
error: (yuidoc): Scanned 5001 directories looking for a yuidoc.json file, something is probably wrong here..
Thanks for help!
The warning is nothing to worry about.
The error is that you haven't provided a yuidoc.json file:
