To be able to do this Vim loads each file as if it is being edited.  When
there is no match in the file the associated buffer is wiped out again.  The
'hidden' option is ignored here to avoid running out of memory or file
descriptors when searching many files.  However, when the |:hide| command
modifier is used the buffers are kept loaded.  This makes following searches
in the same files a lot faster.

Note that |:copen| (or |:lopen| for |:lgrep|) may be used to open a buffer
containing the search results in linked form.  The |:silent| command may be
used to suppress the default full screen grep output.  The ":grep!" form of
the |:grep| command doesn't jump to the first match automatically.  These
commands can be combined to create a NewGrep command: >

        command! -nargs=+ NewGrep execute 'silent grep! <args>' | copen 42


5.1 Using Vim's internal grep

					*:vim* *:vimgrep* *E682* *E683*
:vim[grep][!] /{pattern}/[g][j][f] {file} ...
			Search for {pattern} in the files {file} ... and set
			the error list to the matches.  Files matching
			'wildignore' are ignored; files in 'suffixes' are
			searched last.

			{pattern} is a Vim search pattern.  Instead of
			enclosing it in / any non-ID character (see
			|'isident'|) can be used, so long as it does not
			appear in {pattern}.
			'ignorecase' applies.  To overrule it put |/\c| in the
			pattern to ignore case or |/\C| to match case.
			'smartcase' is not used.
			If {pattern} is empty (e.g. // is specified), the last
			used search pattern is used. |last-pattern|

			Flags:
			'g'  Without the 'g' flag each line is added only
			     once.  With 'g' every match is added.

			'j'  Without the 'j' flag Vim jumps to the first
			     match.  With 'j' only the quickfix list is
			     updated.  With the [!] any changes in the current
			     buffer are abandoned.

			'f'  When the 'f' flag is specified, fuzzy string
			     matching is used to find matching lines. In this
			     case, {pattern} is treated as a literal string
			     instead of a regular expression.  See
			     |fuzzy-matching| for more information about fuzzy
			     matching strings.

			|QuickFixCmdPre| and |QuickFixCmdPost| are triggered.
			A file that is opened for matching may use a buffer
			number, but it is reused if possible to avoid
			consuming buffer numbers.

:{count}vim[grep] ...
			When a number is put before the command this is used
			as the maximum number of matches to find.  Use
			":1vimgrep pattern file" to find only the first.
			Useful if you only want to check if there is a match
			and quit quickly when it's found.

			Every second or so the searched file name is displayed
			to give you an idea of the progress made.
			Examples: >
				:vimgrep /an error/ *.c
				:vimgrep /\<FileName\>/ *.h include/*
				:vimgrep /myfunc/ **/*.c
<			For the use of "**" see |starstar-wildcard|.

:vim[grep][!] {pattern} {file} ...
			Like above, but instead of enclosing the pattern in a
			non-ID character use a white space separated pattern.
			The pattern must start with an ID character.
			Example: >
				:vimgrep Error *.c
<
							*:lv* *:lvimgrep*
:lv[imgrep][!] /{pattern}/[g][j][f] {file} ...
:lv[imgrep][!] {pattern} {file} ...
			Same as ":vimgrep", except the location list for the
			current window is used instead of the quickfix list.

						*:vimgrepa* *:vimgrepadd*
:vimgrepa[dd][!] /{pattern}/[g][j][f] {file} ...
:vimgrepa[dd][!] {pattern} {file} ...
			Just like ":vimgrep", but instead of making a new list
			of errors the matches are appended to the current
			list.

						*:lvimgrepa* *:lvimgrepadd*
:lvimgrepa[dd][!] /{pattern}/[g][j][f] {file} ...
:lvimgrepa[dd][!] {pattern} {file} ...
			Same as ":vimgrepadd", except the location list for
			the current window is used instead of the quickfix
			list.

5.2 External grep

Vim can interface with "grep" and grep-like programs (such as the GNU
