Hi,

I have nano configured for autosave on exit but if I open a file to which I don't have write access it will happily make changes to the text that it can't save.

When I go to save or exit it shows a permissions error with a continue / cancel choice. That leaves me back in the editor with unsaved changes.

The only way out of this seems to be to close the terminal from which nano was run or use a separate terminal to kill that process.

Is there a clean way, from within nano, to tell it to abandon changes and quit anyway?

I can't find one.

TIA, Gentree. 8)

I don't recall if this is standard, but nano here has Ctl-X bound to exit (Close the current file buffer / Exit from nano). When I edit a file that I lack permissions to write, and Ctl-X, nano asks ...

Code:
Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ?


... To which I answer "n" and nano quits.

I just noticed that you have autosave on exit. I don't. I tried `nano -t` and got the same result you did. Was able to exit by saving the changed file in a temporary place, just prepended "/tmp/" and got out. Beats killing the nano process, but isn't as graceful as one might like.

yes, thanks, at least it's a work around. I just wondered whether I was missing a command key or something. Maybe not.

I didn't care for writing the modified but not save-able file out to disk, and found out that changing the filename to /dev/null allows nano to dutifully bail out.
