问题
I'm a newbie to Linux. Is there a way to see the control characters in gedit. I went to options->preferences and all I got is option to see the line numbers of the text file. Is there any plugin that needs to be installed to see the same? I'm on Ubuntu 12.04 LTS and the gedit version is 3.4.1.
回答1:
There is a gedit-plugins package available for Ubuntu. Install that and take a look at the Draw Spaces section in the gedit preferences. You can configure it to show spaces, tabs, line feeds etc.
You can use this command in a terminal: sudo apt-get install gedit-plugins

As said in the other answer you need to install the Draw-Spaces plugin in gedit. Once there, I must say, the plugin options are confusing because the word space is used with two different meanings, as separation character (including tab) or as a proper space.
For most applications you need these options. This specific combinations, will show leading and trailing proper spaces and not show tabs. (This way you can, for example, tell if indentation was not done with tabs).
