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

vi
(^), the editor displays the screenful before that. If type is an equal sign (=),
the current line is centered on the screen with a line of hyphens printed
immediately before and after it. The current line indicator points to the last
line displayed.
[.,.] ), each one causes another shift. The
current line indicator points to the last line displayed. If a count is specified,
that many lines are shifted.
[range] ! command
Submits command to be run by the command interpreter named by the
SHELL variable. If range is given, the command is invoked with the
contents of that line range as input. The output from the command then
replaces that line range. Thus:
1,$!sort
sorts the entire contents of the file.
Substitutions are made in command before it is run. Any occurrences of an
exclamation mark (!) are replaced by the previous command line, while
occurrences of percentage (%) and hash mark (#) characters are replaced
with the pathnames of the current and alternate files, respectively. If any
such substitutions actually take place, the new command line is displayed
before it is executed. (See the read and write sections in “ex Command
Mode” on page 769 for more information about the current and alternative
files.)
If the file has been modified and the variable autowrite is on, the file is
written before calling the command. If autowrite is off, a warning message
is given.
[$] = Displays the given line number. The default line number is the last line of
the file. The current line indicator is not changed.
“ a line of text
This is a comment.
[.,.] & [options] [count] [flags]
Repeats the last substitute command. If any options, count, or flags are
specified, they replace the corresponding items in the previous substitute
command.
[.,.] ~ [options] [count] [flags]
Repeats the last substitute command. However, the regular expression
that is used is the last regular expression; that is, if there has been a
search, the search’s regular expression is used. The simple substitute with
no arguments, or the & command, uses the regular expression from the
previous substitute. substitute with an empty regular expression uses the
last regular expression, like ~. If any options, count, or flags are specified,
they replace the corresponding items in the previous substitute command.
