Save as with gedit [closed]

I have a file that I'm going to be editing and then saving multiple copies of so that I can run them in a model I'm using.

Having edited the file I now don't seem to be able to save it under a different name.

gedit NAMELIST.IN &

(I then edited the text within the file)

I definitely need the original file back. I can't any nice simple GUI button thing at the top of the window(?) for this. Is there a command line way to do this nice and neatly?

Ideally I'd like to save the file as

TMB_RUN_1_NAMELIST.IN

EDIT*** Save as is greyed out. However, the shortcut Crtl+Shift+S is working? And I've found that I can save it by right clicking on the gedit tab.

Any thoughts on why Save As might be greyed out and how I might be able to look at that would be welcome. ***EDIT

Solution 1:

Sounds like a gedit bug. Specifically, this one:

Solution 2:

gedit(GUI) provide the Save As option. You can either press Ctrl+shift+S or can go to File=> Save As or Right click on the file name, it gives you the Save As Option.

This may help you. But yes there is no direct button to save as.(In GUI)

Solution 3:

The "File" item on gedit's File-Edit-View... menu should have options for: New, Open, Save - and Save As.
