I have a text with a lots of lines, my question is how to delete the repeat lines in emacs? using the command in emacs or elisp packages without external utils.
for example:
this is line a
this is line b
this is line a
to remove the 3rd line (same as 1st line)
this is line a
this is line b
解决方案
Put this code to your .emacs:
(defun uniq-lines (beg end)
"Unique lines in region.
Called from a program, there are two arguments:
BEG and END (region to sort)."
(interactive "r")
(save-excursion
(save-restriction
(narrow-to-region beg end)
(goto-char (point-min))
(while (not (eobp))
(kill-line 1)
(yank)
(let ((next-line (point)))
(while
(re-search-forward
(format "^%s" (regexp-quote (car kill-ring))) nil t)
(replace-match "" nil nil))
(goto-char next-line))))))
Usage:
M-x uniq-lines
