ed
did not specify file, ed uses the remembered filename, if any. In all cases,
the e subcommand sets the remembered filename to the file that it has just
read into the buffer. ed displays a count of the bytes in the file unless it is in
quiet mode. If you have changed the current buffer since the last time its
contents were written, ed warns you if you try to run an e subcommand,
and does not run the subcommand. If you enter the e subcommand a
second time, ed goes ahead and runs the command.
f [file] Changes the remembered filename to file. ed displays the new
remembered filename. If you do not specify file, ed displays the current
remembered filename.
1,$G/regexp/
Is similar to the g command except that when ed finds a line that matches
regexp, it prints the line and waits for you to type in the subcommand to be
run. You cannot use the a, c, i, g, G, v, and V subcommands. If you enter
&, the G subcommand reruns the last subcommand you typed in. If you just
press , G does not run any subcommand for that line. Note that the
subcommands input as part of the execution of the G subcommand can
address and affect any lines in the buffer. If the variable _UNIX03 is set to
YES, any line modified by the subcommand will be unmarked.
1,$g/regexp/command
Performs command on all lines that contain strings matching the regular
expression regexp. This subcommand works in two passes. In the first
pass, ed searches the given range of lines and marks all those that contain
strings matching the regular expression regexp. The second pass performs
command on those lines. If the variable _UNIX03 is set to YES, any line
modified by the command will be unmarked. You cannot use !, g, G, V, or v
as command. command consists of one or more ed subcommands, the first
of which must appear on the same line as the g subcommand. All lines of a
multiline command list, except the last, must end with a backslash (\). If
command is empty, ed assumes it to be the p subcommand. If no lines
match regexp, ed does not change the current line number; otherwise, the
current line number is the one set by the last subcommand in command.
Instead of the slash (/) to delimit regexp, you can use any character other
than space or newline.
H Tells ed to display more descriptive messages when errors occur. If ed is
already printing descriptive messages, H returns to terse error messages.
Normally, ed indicates error messages by displaying a ?. When you turn on
descriptive error messages with this subcommand, ed also displays the
descriptive message for the most recent ? message.
h Provides a brief explanation of the last error that occurred. This does not
change the current line number.
.i Works similarly to the a subcommand, except that ed places the text before
the addressed line. Valid addresses range from line 1 to $ (the last line). ed
sets the current line number to the last inserted line. If the variable
_UNIX03 is set to YES, address 0 is valid for this subcommand and it will
be interpreted as if address 1 were specified.
.,.+1j Joins a range of lines into one line. To be precise, the j command removes
all newline characters from the addressed range of lines, except for the last
one. ed sets the current line number to the resulting combined line.
.kx Marks the addressed line with the mark name x, which is any single
lowercase letter of the alphabet. This lets you refer to a marked line with
