Remove unsaved text in Emacs
Is there a way to remove unsaved text and get back the latest saved state of a file in Emacs without using undo?
Like this:
| a - write some text to save
| b - save the file
| c - add some text to remove
| d - more text to remove
| e - command/function to remove all text after b

Do you mean for the sequence to bea-b-c-d-einstead ofa-b-c-d-d?

Use M-x revert-buffer. A buffer only visits a file. The revert-buffer function reloads the current buffer's source file from disk. So long as the file hasn't changed since you last saved it, as might happen if another process writes to it, revert-buffer will restore the buffer to point b, removing all text inserted after b.
As a bonus, you don't need to type the whole thing. Typing M-x rev-b is sufficient.
