In sed, one can delete every line matching a pattern with the command
"/pattern/d". In vi, using the analagous command ":/pattern/d" only deletes the first line that matches the pattern. How do you delete all the lines that match the pattern? ":g/pattern/d" (:g[lobal] lets you apply an ex command to every line matching a pattern)

if anybody has any vim tips they'd like to share, i'd love to see a
thread of people's favorite vim tricks.

here's another one i learned just recently:


1 one 2 two 3 three 4 four 5 five 6 six 7 seven 8 eight 9 nine

use line highlighting (shift v) and highlight lines 4, 5, and 6.
type "zf".
you've now "folded" lines 2, 3, 4, 5, and 6:

1 one
+--  5 lines: 2----------------------------------------------------
7 seven
8 eight
9 nine

now use line highlighting to to highlight the first 4 lines.
type "zf"
you've now folded the first four line:

+--  8 lines: 1----------------------------------------------------
9 nine

place the cursor somewhere on the fold.
type "zo" to unfold:

1 one
+--  5 lines: 2----------------------------------------------------
7 seven
8 eight
9 nine

place the cursor somewhere on the fold.
type "zo" to unfold again:

1 one
2 two
3 three
4 four
5 five
6 six
7 seven
8 eight
9 nine


really great for programming. one of the uses is when i'm editing a function and need to see another function that's way down in the source file. i can bring them "close together" by folding.

previously, i either moved the functions using block cut and copy (ick)
or by using vim's marks (better, but still ick).


zf: fold the highlighted selection. it can take movement commands too, like "zf}" to fold the next paragraph.

zo: open a fold. the cursor must be on top of the proper fold.

zc: refold the last fold.

what would be nice is if we could have "named folds", like named
registers or named marks.


wouldn't mind hearing other people's tips.... :-)
