1.3. Why the name change from TIP?

On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program "establishes a full duplex terminal connection to a remote host", and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).

    3.2. Compiling from source: WHAT THE HECK DO I DO NOW?

    -

    3.7. Tell me more about this multibuffer stuff!

    +

    3.6. Tell me more about this multibuffer stuff!

    To use multiple file buffers, you must not have configured nano with --disable-multibuffer nor with --enable-tiny (use nano -V to check the compilation options). Then when you want to insert a file into its own buffer instead of into the current file, just hit Meta-F after typing ^R. If you always want files to be loaded into their own buffers, use the -F or --multibuffer flag when you invoke nano, or add set multibuffer to your .nanorc file.

    You can move between the buffers you have open with the Meta-< and Meta-> keys, or more easily without holding Shift: Meta-, and Meta-. (clear as mud, right? =-). When you have more than one buffer open, the ^X shortcut will say "Close", instead of "Exit".

    3.7. Tell me more about this verbatim input stuff!

    When you want to insert a literal character into the file you're editing, such as a control character that nano usually treats as a command, first press Meta-V (if you're not at a prompt, you'll get the message "Verbatim Input" on the status bar), then press the key(s) that generate the character you want.

    Alternatively, if Unicode support is enabled (see section 5.3), you can press Meta-V and then type a six-digit hexadecimal code (from 000000 to 10FFFF, case-insensitive), and the character with the corresponding value will be inserted. The status bar will change to "Unicode Input: ......" when you do this.

    3.9. How do I make a .nanorc file that will be read when I start nano?

    -

    It's not hard at all! But, your nano must not have been compiled with --disable-nanorc. Then simply copy the sample.nanorc that came with the nano source or your nano package (most likely in /usr/doc/nano) to .nanorc in your home directory. If you didn't get one, the syntax of the file is simple. Flags are turned on and off by using the words set and unset plus the long option name for the feature. For example, "set nowrap" or "set smarthome".

    +

    3.8. How do I make a .nanorc file that will be read when I start nano?

    +

    It's not hard at all! Simply copy the sample.nanorc from the doc/ directory in the nano source package (or from /usr/doc/nano on your system) to .nanorc in your home directory, and then edit it. If you didn't get a sample nanorc, the syntax of the file is simple: features are turned on and off by using the words set and unset followed by the long option name of the feature (see man nanorc for the full list of options). For example, "set quickblank" or "set smarthome". Of course, for this to work, your nano must not have been compiled with --disable-nanorc.

    +

    3.9. Why does my self-compiled nano not read /etc/nanorc?

    +

    By default (see 3.3), nano gets installed into /usr/local. This also means that, at startup, nano will read /usr/local/etc/nanorc instead of /etc/nanorc. You can make a symlink from the former to the latter if you want your self-compiled nano to read the same nanorc as the system-installed nano. Or you can configure your nano to overwrite the system nano (again, see 3.3).
