Remove all lines containig a keyword

Remove all lines containig a keyword

[Christian Herenz]

Hi,
I have a huge list of "stuff" I sell / sold.
To print out an actual list, without the stuff that is sold already, It would be 
nice to have a command for doing this task automated - Remove all lines with the 
keyword "sold".
Thanks for your Help,
Christian

grep?

or M-x flush-lines

Re: Remove all lines containig a keyword

[harven]

M-x replace-regexp RET .*Sold.* C-o RET RET
also works.

Org-mode is great for this kind of thing. It allows searches and views
by tags, as well as customized cycling of states (eg FORSALE --> BIDFOR
--> SOLD).

We're getting far afield. The simple answer to the OP's question, as has already
been said, is `M-x flush-lines' (aka `delete-matching-lines').

you can just use M-x delete-matching-lines.

Note that there's also list-matching-lines.

Thanks.. I even bookmarked your site.. But sometimes you don't know where to 
find something, if you need it. I use emacs now for 2 years, and still I do some 
things manually, where I think there is an emacs-command. But I am just a 
student, and maybe looking up a particular command is at first not so fast, as 
doing a specific task manually - and my fellow students may have changed their 
codes faster than me, because I still fiddle out what keys next to press... But 
I think there is a long-term benifit from trying to avoid the mouse while inside 
emacs.


Greets,
Christian

Looks like you have several suggestions. I'll chime in with M-x
flush-lines.

RE: Remove all lines containig a keyword

[Bourgneuf Francois]

C-M-% .*sold.*C-q C-j Enter !

I explain :
C-M-% : query-replace-regexp
.*sold.*C-q C-j : 0-n character followed by "sold" followed by 0-n character followed by NEWLINE ( C-q C-j )

Hide-lines.el is also useful

http://www.emacswiki.org/cgi-bin/wiki/hide-lines.el

from the commentary...


;; Now, when you type C-c h, you will be prompted for a regexp
;; (regular expression).  All lines matching this regexp will be
;; hidden in the buffer.
;; 
;; Alternatively, you can type C-u C-c h (ie. provide a prefix
;; argument to the hide-lines command) to hide all lines that *do not*
;; match the specified regexp.
;; 
;; If you want to make all of the hidden areas re-appear again, type:
;; M-x show-all-invisible
;; Or you can bind show-all-invisible to a key and use that to show
;; all the hidden areas again.






And from the emacs manual...

20.10 Other Search-and-Loop Commands
====================================

Here are some other commands that find matches for a regular
expression.  They all ignore case in matching, if the pattern contains
no upper-case letters and `case-fold-search' is non-`nil'.  Aside from
`occur' and its variants, all operate on the text from point to the end
of the buffer, or on the active region in Transient Mark mode.

`M-x occur <RET> REGEXP <RET>'
     Display a list showing each line in the buffer that contains a
     match for REGEXP.  To limit the search to part of the buffer,
     narrow to that part (*note Narrowing::).  A numeric argument N
     specifies that N lines of context are to be displayed before and
     after each matching line.  Currently, `occur' can not correctly
     handle multiline matches.

     The buffer `*Occur*' containing the output serves as a menu for
     finding the occurrences in their original context.  Click
     `Mouse-2' on an occurrence listed in `*Occur*', or position point
     there and type <RET>; this switches to the buffer that was
     searched and moves point to the original of the chosen occurrence.
     `o' and `C-o' display the match in another window; `C-o' does not
     select it.

     After using `M-x occur', you can use `next-error' to visit the
     occurrences found, one by one.  *Note Compilation Mode::.

`M-x list-matching-lines'
     Synonym for `M-x occur'.

`M-x multi-occur <RET> BUFFERS <RET> REGEXP <RET>'
     This function is just like `occur', except it is able to search
     through multiple buffers.  It asks you to specify the buffer names
     one by one.

`M-x multi-occur-in-matching-buffers <RET> BUFREGEXP <RET> REGEXP <RET>'
     This function is similar to `multi-occur', except the buffers to
     search are specified by a regular expression that matches visited
     file names.  With a prefix argument, it uses the regular
     expression to match buffer names instead.

`M-x how-many <RET> REGEXP <RET>'
     Print the number of matches for REGEXP that exist in the buffer
     after point.  In Transient Mark mode, if the region is active, the
     command operates on the region instead.

`M-x flush-lines <RET> REGEXP <RET>'
     This command deletes each line that contains a match for REGEXP,
     operating on the text after point; it deletes the current line if
     it contains a match starting after point.  In Transient Mark mode,
     if the region is active, the command operates on the region
     instead; it deletes a line partially contained in the region if it
     contains a match entirely contained in the region.

     If a match is split across lines, `flush-lines' deletes all those
     lines.  It deletes the lines before starting to look for the next
     match; hence, it ignores a match starting on the same line at which
     another match ended.

`M-x keep-lines <RET> REGEXP <RET>'
     This command deletes each line that _does not_ contain a match for
     REGEXP, operating on the text after point; if point is not at the
     beginning of a line, it always keeps the current line.  In
     Transient Mark mode, if the region is active, the command operates
     on the region instead; it never deletes lines that are only
     partially contained in the region (a newline that ends a line
     counts as part of that line).

     If a match is split across lines, this command keeps all those
     lines.
