Missing two entries. The descriptions are for my personal notes. I have
no opinion whether they should be included.
3.2 |sed| commands summary
$ Last line of last input file.
a\ Append text after a line.
text
a text Append text after a line.
b label Branch to label.
missing c Comment, newline delimited.
c\ Change lines with text.
text
c text Change lines with text.
d Delete pattern space and start next cycle.
D If pattern space contains newlines, delete text up to the
first newline, and restart cycle with the resultant pattern
space, without reading a new line of input.
e Executes the command that is found in pattern space in the
shell, and replaces the pattern space with the output; a
trailing newline is suppressed.
e command Executes command in the shell, and sends its output to the
output stream.
F Print the file name of the current input file
g Replace the contents of the pattern space with the contents
of the hold space.
G Append a newline to the contents of the pattern space, and
then append the contents of the hold space to that of the
pattern space.
h Replace the contents of the hold space with the contents of
the pattern space.
H Append a newline to the contents of the hold space, and then
append the contents of the pattern space to that of the hold
space.
i\ Insert text before a line.
text
i text Insert text before a line.
missing l [num] Print the pattern space in an unambiguous form
and wrap after
num columns.
n If auto-print is not disabled, print the pattern space, then
replace the pattern space with the next line of input.
N appends the next line from the input file to the pattern space.
p If auto-print is not disabled, print the pattern space, then,
regardless, replace the pattern space with the next line of
input. If there is no more input then sed exits without
processing any more commands.
P Print the pattern space, up to the first <newline>.
q[num] Print pattern-space and exit with optional exit code, num.
Q[num] Do not print pattern-space and exit with optional exit code,
num.
r filename Reads file filename.
R filename Queue a line of filename to be read and inserted into the
output
stream at the end of the current cycle, or when the next input
line is read.
s///[flags] Match the regular-expression against the content of the pattern
space and replace with replacement.
t [label] Branch to label if there has been a successful substitution or
conditional branch. If no label the next cycle is started.
T [label] Branch to label if there has been no successful substitution or
conditional branch. If no label the next cycle is started.

W filename Write to the given filename the portion of the pattern space up
to the first newline.
x Exchange the contents of the hold and pattern spaces.
