I open a file in Ubuntu nano editor from the comand line and I want to copy all the contents of the file so I can paste it in an another application outside the shell.

So far I can only copy using shift on the screen that is visible but not on all content.

Are you in a command line only environment? If not, why don't you open the file in something like gedit? – MBraedley Oct 6 '10 at 10:50
I don't have gedit on that machine and I want to learn to do it in nano. – Elzo Valugi Oct 6 '10 at 14:09
Btw this is why I hate linux and the command-line: In theory a wonderful thing, but in reality extremely unuintutive, even the most simple and common things don't work like expected. Usability Super-Fail. – Sliq Sep 16 '13 at 21:08
nano is not powerful. just to edit some config files it is pretty ok, but as an code editor it sucks! – B4NZ41 Jan 17 '14 at 16:32

You can't use the buffer of nano to use it elsewhere, you need to use the buffer of X or Gnome.

xclip is the solution.

A command line interface to the X11 clipboard. It can also be used for copying files, as an alternative to sftp/scp, avoiding password prompts when X11 forwarding has already been setup.

There is a possible way:

  • Cursor at the beginning of a file

  • Ctrl6 to set a mark

  • AltShiftT (or try AltT) to cut to the end of the file

  • If AltT doesn't work, try CtrlK

  • to just copy the file content do CtrlU to uncut the text again

nice trick, but I wanted a copy not a cut. – Elzo Valugi Jan 18 '11 at 19:41
this works only inside nano - after you'll close it you can not uncut it in another app as OP wanted. – A.D. Mar 29 '15 at 13:28
how do you get text OUT of nano? that's what I need to figure out – anon58192932 Sep 24 '15 at 18:04

Actually, this answer might be a bit late but I was looking for an answer for the same question and I just figured it out. when you have the file you want to copy to open in nano. you can hit ctl-R and enter the file you want copied from. this will bring in the whole file.

In my case I was just copying my old fstab so it wasn't a big deal. but could get ridiculous with huge files.

Here's another solution. One that I personally prefer. It uses Xsel. It's very similar to Xclip but with a key difference.

$ cat my_funky_file | xsel

While Xclip puts everything in the main clipboard, Xsel manipulates the selection buffer letting you paste the selection with a middle-click. This is great for one-offs! So if you have something in your clipboard that you haven't pasted yet, that would stay unaffected!

And if you want to paste the content, xsel -o will spit it right out.

You can install it on a debian based system using

$ apt-get install xsel

The source is available here otherwise! Hope this helps someone.

From my understanding it is not possible to select an entire file in nano if it scrolls more then your window. If you are using a GUI and have nano open from a terminal and the file is not longer than your window you can use mouse and select all the text than cnt+shift+c will copy it to clipboard.

Although not in nano, there is a way in vim. See here.

Specifically, select text (visual mode) section.

You can cut from the current cursor position to the end of the file with meta key plus T. Meta key is either alt or escape, depending on your keyboard. For me, accessing Ubuntu via ssh from my OSX it was escape.
