I can't imagine how "not to read into a buffer"... I just tried something like this, and it works: (defun process-file (file) (interactive "f") (with-temp-buffer (insert-file-contents file) (delete-non-matching-lines "valid [0-9]+") (replace-regexp "valid \\([0-9]+\\)" "I found a \\1" ) (write-file "test2.txt" nil))) -------- input file ---------------- blablabla valid 39 idasuiahsduihas valid 123 dasuiohdiuahs dasuiohduahs dasudhas valid 29 dasiuhuidah dasjddij d d asijdsj -------- output file -------- I found a 39 I found a 123 I found a 29 Don't know if you can use something from that, but anyway :) Good luck, HS
