a,bN Appends the next line of input to the end of the pattern buffer, using a new
line to separate the appended material from the original. The current line
number changes.
a,bp Prints the text in the pattern buffer to the standard output. The –n option
does not disable this form of output. If you do not use –n, the pattern buffer
is printed twice.
a,bP Operates like the p subcommand, except that it prints the text in the pattern
buffer only up to and including the first newline character.
aq Quits sed, skipping the rest of the script and reading no more input lines.
ar file Reads text from file and writes it to the standard output before reading the
next input line. The timing of this operation is the same as for the a
subcommand. If file does not exist or cannot be read, sed treats it as an
empty file.
a,bs/reg/ sub/[gpn] [wfile]
Substitutes the new text string sub for text matching the regular expression,
reg. Normally, the s subcommand replaces only the first such matching
string in each input line. You can use any single printable character other
than space or newline instead of the slash (/) to delimit reg and sub. The
delimiter itself may appear as a literal character in reg or sub if you precede
it with a backslash (\). You can omit the trailing delimiter.
If an ampersand (&) appears in sub, sed replaces it with the string
matching reg. For more information, see Appendix C. A \n in reg matches
an embedded newline in the pattern buffer (resulting, for example, from an
N subcommand). The subcommand can be followed by a combination of
the following:
n Substitutes only the nth occurrence of regexp.
g Replaces all non-overlapping occurrences of regexp rather than the
default first occurrence. If both g and n are specified, the last one
specified takes precedence.
p Executes the print (p) subcommand only if a successful substitution
occurs.
w file Writes the contents of the pattern buffer to the end of file, if a
substitution occurs. When the variable _UNIX03=YES is set, the file
must be preceded with one or more s. When the variable
_UNIX03 is unset or is not set to YES, zero separation
between w and file is allowed.
a,bt [label]
Branches to the indicated label if a successful substitution has occurred
since either reading the last input line or running the last t subcommand. If
you do not specify label, sed branches to the end of the script.
a,bw file
Writes the text in the pattern buffer to the end of file.
a,bx Exchanges the text in the hold buffer with that in the pattern buffer.
sed
a,by/set1/set2/
Transliterates any input character occurring in set1 to the corresponding
element of set2. The sets must be the same length. You can use any
character other than backslash or newline instead of the slash to delimit the
strings.
