global

:[2addr]g[lobal]/pattern/[commands]
:[2addr]v/pattern/[commands]

otherwise if commands are empty: mark lines containing pattern
otherwise executes all commands for each line matching pattern, commands separated by |, or (for v) executes all commands for each line not matching pattern

goto

:[1addr]

Goto specified address. Addresses are constructed as follows: - The character '.' (period) shall address the current line. - The character '$' shall address the last line of the edit buffer. - The positive decimal number n shall address the nth line of the edit buffer. - The address "'x" refers to the line marked with the mark name character 'x', which shall be a lowercase letter from the portable character set, the backquote character, or the single-quote character. It shall be an error if the line that was marked is not currently present in the edit buffer or the mark has not been set. Lines can be marked with the ex mark or k commands, or the vi m command. - A regular expression enclosed by slash characters ( '/' ) shall address the first line found by searching forwards from the line following the current line toward the end of the edit buffer and stopping at the first line for which the line excluding the terminating newline matches the regular expression. As stated in Regular Expressions in ex, an address consisting of a null regular expression delimited by slash characters ( "//" ) shall address the next line for which the line excluding the terminating newline matches the last regular expression encountered. In addition, the second slash can be omitted at the end of a command line. If the wrapscan edit option is set, the search shall wrap around to the beginning of the edit buffer and continue up to and including the current line, so that the entire edit buffer is searched. Within the regular expression, the sequence "\/" shall represent a literal slash instead of the regular expression delimiter. - A regular expression enclosed in question-mark characters ( '?' ) shall address the first line found by searching backwards from the line preceding the current line toward the beginning of the edit buffer and stopping at the first line for which the line excluding the terminating newline matches the regular expression. An address consisting of a null regular expression delimited by question-mark characters ( "??" ) shall address the previous line for which the line excluding the terminating newline matches the last regular expression encountered. In addition, the second question-mark can be omitted at the end of a command line. If the wrapscan edit option is set, the search shall wrap around from the beginning of the edit buffer to the end of the edit buffer and continue up to and including the current line, so that the entire edit buffer is searched. Within the regular expression, the sequence "\?" shall represent a literal question-mark instead of the RE delimiter. - A plus or a minus ( '+-' ) followed by a decimal number shall address the current line plus or minus the number. A '+' or '-' not followed by a decimal number shall address the current line plus or minus 1.

source

substitute

:[2addr]s[ubstitute]/pattern/repl/[options]
:[2addr]&[options]
:[2addr]~[options]

Replace the first instance of the pattern pattern by the string repl on each specified line. If both pattern and repl are not specified or are empty (for example, "//" ), the last s command is repeated. If only pattern is not specified or is empty, the last regular expression used in the editor is used as the pattern.
Supported options:
i: ignore case
c: ask for confirmation
g: global, otherwise only first match on line
When substituting you can use:

• & or \0 to represent the target,
• \U to convert to uppercase,
• \L to convert to lowercase,
• $ to match a line end, e.g. %s/$/EOL appends the string EOL at the end of each line.
• ~ to match against a previous replacement string.

Merging is not yet possible using a \n target, you can create a macro for that.

Any character

(

This marks the start of a region for tagging a match.

)

This marks the end of a tagged region.

\int

The result of the submatch whose opening parenthesis is the int-th (int shall begin by a digit other than 0). For example, if the search string was Fred\([1-9]\)XXX and the replace string was Sam\1YYY, when applied to Fred2XXX this would generate Sam2YYY. \0 refers to all of the matching text.

\b

This matches a word boudary.

\x

This allows you to use a character x that would otherwise have a special meaning. For example, \[ would be interpreted as [ and not as the start of a character set.

[...]

The target character is part of the class, for example, [abc] means any of the characters a, b or c. You can also use ranges, for example [a-z] for any lower case character.

[^...]

The target character is not part of the class. For example, [^A-Za-z] means any character except an alphabetic character.

^

This matches the start of a line (unless used inside a class, see above).

$

This matches the end of a line.

*

This matches 0 or more times. For example, Sa*m matches Sm, Sam, Saam, Saaam and so on.

+

This matches 1 or more times. For example, Sa+m matches Sam, Saam, Saaam and so on.
