ed
the current line to the last line on which a substitution occurred. If ed makes
no such replacements, ed considers it an error.
flags can be one of the following:
n Replaces the nth matching string in the line instead of the first one.
g Replaces every matching string in each line, not just the first one.
l Displays the new current line in the format of the l subcommand.
n Displays the new current line in the format of the n subcommand.
p Displays the new current line in the format of the p subcommand.
You can use any single printable character other than space or newline
instead of / to separate parts of the subcommand provided that you use the
same character to delimit all parts of the subcommand. You can omit the
trailing delimiter.
You can include a newline in the new string by putting a \ immediately in
front of the newline. This is a good way to split a line into two lines. If new
consists only of the % character, s uses the new string from the previous s
command. If the variable _UNIX03=YES is set and there was no previous s
command, the use of % in this manner is an error. If & appears anywhere in
new, ed replaces it with the text matching the regexp. If you want new to
contain a literal ampersand, or percent sign, put a backslash (\) in front of
the & or % character.
.,.ta Copies the addressed lines to the point after the line given by the address
a. The address a must not fall in the range of addressed lines. If address a
is 0, ed copies the lines to the beginning of the buffer. This sets the current
line to the last line copied.
u Rolls back the effect of the last subcommand that changed the buffer. For
the purposes of u, subcommands that change the buffer are: a, c, d, g, G,
i, j, m, r, s, t, v, V, and (of course) u. This means that typing u repeatedly
switches the most recent change back and forth. This subcommand sets
the current line number to the value it had immediately before the
subcommand being undone started.
1,$V/regexp/
Is similar to the G subcommand, except that this subcommand gives you
the chance to edit only those lines that do not match the given regular
expression.
1,$v/regexp/commands
Is similar to the g (global) command, except that ed applies the given
commands only to lines that do not match the given regular expression.
1,$W [file]
Is similar to the w subcommand, except that this command appends data to
the given file if the file already exists.
1,$w [file]
Writes the addressed lines of the buffer to the named file. This does not
change the current line. If you do not provide file, ed uses the remembered
filename; if there is no remembered filename, file becomes the remembered
name. If the output file does not exist, ed creates it. ed displays the number
of characters written unless you had specified the –s option.
X Prompts you to enter an encryption key. All subsequent e, r, and w
subcommands use this key to decrypt or encrypt text read from or written to
files. To turn encryption off, issue an X subcommand and press in
response to the prompt for an encryption key.
