===== Поиск и замена текста =====

<box round 80%|[[http://www.vim.org/tips/tip.php?tip_id=31|Tip #31: Find and Replace]]>
To find and replace one or more occurences of a given text pattern with a
new text string, use the s[ubstitute] command.

There are a variety of options, but these are what you most probably want:

||'':%s/foo/bar/g''          | find each occurance of 'foo' and replace it with 'bar' without asking for confirmation||
||'':%s/foo/bar/gc''         | find each occurance of 'foo' and replace it with 'bar' asking for confirmation first||
||'':%s/<foo>/bar/gc''     | find (match exact word only) and replace each occurance of 'foo' with 'bar'||
||'':%s/foo/bar/gci''        | find (case insensitive) and replace each occurance of 'foo' with 'bar'||
||'':%s/foo/bar/gcI''        | find (case sensitive) and replace each occurance of 'foo' with 'bar'||

<note>Without the 'g' flag, replacement occurs only for the first occurrence in each line.</note>

For a full description and some more interesting examples of the substitute command refer to

Замена результатов предыдущего поиска:
<code>
/ищем-что-то
:%s//меняем-на-другое/g
</code>
В итоге будет произведена замена ''ищем-что-то'' на строку ''меняем-на-другое''. Плюс в том, что не надо дважды вводить выражение для поиска, и исключается возможность ошибки в написании.

===== Copy and paste text =====

<box round 80%|[[http://www.tech-recipes.com/unix_tips219.html|Copy and paste text with vi or vim]]>
The command 'Y' or 'yy' copies (yanks) one or more lines. To copy one line, two lines, 10 lines, and all lines to the end of the file, respectively:

<code>
Y
2Y
10Y
yG
</code>

To paste the text contained in the buffer above (uppercase P) or below the current cursor position (lowercase p), respectively:

<code>
P
p
</code>

It is also possible to yank text within a line. The following commands yank text from the current cursor position to the end of the word and the end of the line, respectively:

<code>
yw
y$
</code>

The same commands paste the text within a line. Lower case p pastes after the cursor position and upper case P pastes before.

Paste will also work with deleted text, either lines or parts of lines. Be careful not to execute any other commands prior to pasting as this will empty the buffer.

===== Show/hide line numbers =====

<box round 80%|[[http://www.vim.org/tips/tip.php?tip_id=19|Tip #19 - line numbers...]]>
<code>:set number</code>
or shorter:
<code>:set nu</code>
<note tip>An even better way, if you like maps: Put this in your .vimrc file:\\  
'':nmap <C-N><C-N> :set invnumber <CR>''\\
By pressing Ctrl-N twice  (or some other shortcut you fancy) in normal mode, you can toggle between showing and hiding line numbers.</note>
