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

set to either the first or last line of the buffer, depending on whether the
command was issued in vi or ex mode.
ex[!] [+line] [file].
Begins a new editing session on a new file; the new file replaces the old file
on the screen. This command is usually invalid if you have modified the
contents of the current file without writing it back to the file. Specifying an
exclamation mark (!) goes on to start a new session even you have not
saved the changes of the current session.
You can specify line as either a line number or as a string of the form
/regexp or ?regexp where regexp is a regular expression. When line is a
line number, the current line indicator is set to the specified position. When
it has the form /regexp, vi searches forward through the file for the first
occurrence of regexp and sets the current line indicator to that line. ?regexp
is similar to /regexp except that vi searches through the file backwards. If
you omit line and do not specify a file, the value of the current line indicator
does not change. Otherwise, if a file is specified, the current line indicator is
set to either the first or last line of the buffer, depending on whether the
command was issued in vi or ex mode.
f[ile] [file]
Changes the current file name to file and marks it [Not edited]. If this file
exists, it cannot be overwritten without using the exclamation mark (!)
variant of the write command.
[1,$] g[lobal ] [!] /pat/ [commands]
Matches pat against every line in the given range. On lines that match, the
commands are run. If the exclamation mark (!) variant is set, the
commands are run on lines that do not match. This is the same as using
the vi command.
The global command and the undo command cannot occur in the list of
commands. A subsequent undo command undoes the effect of the entire
global command. In ex mode, multiple command lines can be entered by
ending all but the last with a backslash (\). Commands that will take input
are permitted; the input is included in the command list, and the trailing
period (.) can be omitted at the end of the list. For example:
g/rhino/a\
hippo
appends the single line hippo to each line containing rhino. delim is an
arbitrary, nonalphabetic character. The total length of a global command list
is limited (see “Limits” on page 787).
[.] i[nsert][!]
Enter ex INSERT mode, reads text and places it before the specified line.
Otherwise, this is identical to the append command. This command cannot
be entered from vi mode.
[.,.+1] j[oin][!] [count] [flags]
Joins together the lines of text within the range. Unless an exclamation
mark (!) is specified, all white space between adjacent joined lines is
deleted. Two spaces are provided if the previous line ended in a period, no
spaces if the joined line begins with a opening parenthesis, and one space
otherwise.
[.] k x Synonymous with the mark command.
