It is strange there isn’t an option in the EeePC file manager to create a new file so how do you create one? It’s easy enough with the installed text editor kwrite, which can be started up from a terminal window (Ctrl + Alt + T) by simply typing ‘kwrite’. Within kwrite you can then save your new file where you like. If you need to edit a file that requires root permissions then you can use ‘sudo kwrite filename’.
The good old reliable text editor vi is also available in the shape of vim, type ‘man vim’ from a console window for more info.
