I didn’t immediately find any option, in the Gnome terminal a “select all” hotkey can be configured, but this method isn’t optimal even after running clear as the [user@localhost ~] gets also selected. I only want to copy the output of the last command without writing any text file ( don’t know if xsel or xclip can achieve this).
Using any third-party tool is fine as long it’s hosted on Fedora repos. Short & simple commands preferred.
I use an xterm window on gnome, and can easily mark (hold left button and move mouse) what I want to copy with the mouse then a right-click brings up the menu to allow copy.
Once that is done it is in the clipboard to easily paste into almost any other window (or elsewhere on the cli in that same window with another right-click)
