z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

\< Matches the empty string preceding the start of a word. A word is a series
of alphanumeric or underscore characters preceded by and followed by
characters that are not alphanumeric or underscore.
\> Matches the empty string following the end of a word. A word is a series of
alphanumeric or underscore characters preceded by and followed by
characters that are not alphanumeric or underscore.
[string]
Matches any of the characters in the class defined by string. For example,
[aeiouy] matches any of the vowels. You can put a range of characters in a
class by specifying the first and last characters of the range, with a hyphen
(-) between them. For example, in ASCII [A–Za–z] matches any upper or
lowercase letter. If the first character of a class is the caret (^), the class
matches any character not specified inside the square brackets. Thus, in
ASCII [a–z_][^0–9] matches a single alphabetic character or the
underscore, followed by any nonnumeric character.
\( ...\) A set of characters in the pattern can be surrounded by escaped
parentheses. See “Summary of Replacement Patterns” for a discussion of
the \n replacement pattern. This is not affected by the setting of magic.
~ Matches the replacement part of the last substitute command.
A replacement (indicated by repl in the command descriptions) describes what to
put back in a line for the set of characters matched by the regular expression.

& Is replaced by the entire string of matched characters.
~ Is replaced by the entire replacement pattern from the last substitute.
\n Is replaced by the string that matched the nth occurrence of a \( ...\) in the
regular expression. For example, consider:
s/\([a-zA-Z]*\)our/\1or/
The \1 represents the string that matched the regular expression
\([a-zA-Z]*\). Thus the previous command might change the word colour to
color.
\u Turns the next character in the replacement to uppercase.
\l Turns the next character in the replacement to lowercase.
\U Turns the following characters in the replacement to uppercase.
\L Turns the following characters in the replacement to lowercase.
\E, \e Turns off the effects of \U or \L.
You can enter these commands as shown in ex mode. In vi mode, they must be
preceded by the colon (:) character.
ab[breviate] lhs rhs
Indicates that the word lhs should be interpreted as abbreviation for rhs.
(See “Context-Dependent Movement Commands” on page 762 for the
definition of word.) If you enter lhs surrounded by white space in vi INSERT
mode, it is automatically changed into rhs. If you do not specify any
