SED is a stream editor.
|
||||
A stream editor is used to perform basic text
|
||||
transformations on an input stream
|
||||
(a file or input from a pipeline).
|
||||
While in some ways similar to an editor which
|
||||
permits scripted edits (such as ED),
|
||||
SED works by making only one pass over the
|
||||
input(s), and is consequently more efficient.
|
||||
But it is SED's ability to filter text in a pipeline
|
||||
which particularly distinguishes it from other types of
|
||||
editors.

A SED program consists of one or more SED commands,

passed in by one or more of the
|

<CODE>-e</CODE>, <CODE>-f</CODE>, <CODE>--expression</CODE>, and <CODE>--file</CODE>
|

options, or the first non-option argument if zero of these
|

options are used.
|

This document will refer to "the" SED script;
|
||||
this will be understood to mean the in-order catenation
|
||||
of all of the <VAR>script</VAR>s and <VAR>script-file</VAR>s passed in.
|
||||
|
||||
</P>
|
||||
<P>
|
||||
Each SED command consists of an optional address or
|
||||
address range, followed by a one-character command name
|
||||
and any additional command-specific code.

Addresses in a SED script can be in any of the following forms:

<DL COMPACT>
|

<DT><SAMP>`<VAR>number</VAR>'</SAMP>
|

<DD>
|

<A NAME="IDX24"></A>
|

<A NAME="IDX25"></A>
|

Specifying a line number will match only that line in the input.
|
||||
(Note that SED counts lines continuously across all input files.)
|
||||
|
||||
<DT><SAMP>`<VAR>first</VAR>~<VAR>step</VAR>'</SAMP>
|
||||
<DD>
|
||||
<A NAME="IDX26"></A>
|
||||
This GNU extension matches every <VAR>step</VAR>th line
|
||||
starting with line <VAR>first</VAR>.
|
||||
In particular, lines will be selected when there exists
|
||||
a non-negative <VAR>n</VAR> such that the current line-number equals
|
||||
<VAR>first</VAR> + (<VAR>n</VAR> * <VAR>step</VAR>).
|
||||
Thus, to select the odd-numbered lines,
|
||||
one would use <CODE>1~2</CODE>;
|
||||
to pick every third line starting with the second, <CODE>2~3</CODE> would be used;
|
||||
to pick every fifth line starting with the tenth, use <CODE>10~5</CODE>;
|
||||
and <CODE>50~0</CODE> is just an obscure way of saying <CODE>50</CODE>.

||||

<DT><SAMP>`$'</SAMP>

<A NAME="IDX27"></A>
|

<A NAME="IDX28"></A>
|

<A NAME="IDX29"></A>

This address matches the last line of the last file of input.

|

<DD>
|

<A NAME="IDX30"></A>
|

<A NAME="IDX31"></A>
|
||||
This will select any line which matches the regular expression <VAR>regexp</VAR>.
|
||||
If <VAR>regexp</VAR> itself includes any <CODE>/</CODE> characters,
|
||||
each must be escaped by a backslash (<CODE>\</CODE>).

|

<A NAME="IDX32"></A>
|
||||
This also matches the regular expression <VAR>regexp</VAR>,
|
||||
but allows one to use a different delimiter than <CODE>/</CODE>.
|
||||
This is particularly useful if the <VAR>regexp</VAR> itself contains
|
||||
a lot of <CODE>/</CODE>s, since it avoids the tedious escaping of every <CODE>/</CODE>.
|

If <VAR>regexp</VAR> itself includes any delimiter characters,

each must be escaped by a backslash (<CODE>\</CODE>).

The <CODE>I</CODE> modifier to regular-expression matching is a GNU

extension which causes the <VAR>regexp</VAR> to be matched in

a case-insensitive manner.

|

</DL>
|

If no addresses are given, then all lines are matched;

An address range can be specified by specifying two addresses
|
||||
separated by a comma (<CODE>,</CODE>).
|
||||
An address range matches lines starting from where the first
|
||||
address matches, and continues until the second address matches
|
||||
(inclusively).
|
||||
If the second address is a <VAR>regexp</VAR>, then checking for the
|
||||
ending match will start with the line <EM>following</EM> the
|
||||
line which matched the first address.
|
||||
If the second address is a <VAR>number</VAR> less than (or equal to)
|
||||
the line matching the first address,
|
||||
then only the one line is matched.

<A NAME="IDX37"></A>
|
||||
Appending the <CODE>!</CODE> character to the end of an address
|
||||
specification will negate the sense of the match.
|
||||
That is, if the <CODE>!</CODE> character follows an address range,
|
||||
then only lines which do <EM>not</EM> match the address range
|
||||
will be selected.
|
||||
This also works for singleton addresses,
|
||||
and, perhaps perversely, for the null address.

SED maintains two data buffers: the active <EM>pattern</EM> space,
|

and the auxiliary <EM>hold</EM> space.
|
||||
In "normal" operation, SED reads in one line from the
|
||||
input stream and places it in the pattern space.
|
||||
This pattern space is where text manipulations occur.
|
||||
The hold space is initially empty, but there are commands
|

for moving data between the pattern and hold spaces.

If you want to put a comment in the first line of your script

Print out the pattern space (to the standard output).

command-line option.

Note: some implementations of SED, such as this one, will

double-print lines when auto-print is not disabled and the <CODE>p</CODE>

command is given.

Other implementations will only print the line once.

Both ways conform with the POSIX.2 standard, and so neither

way can be considered to be in error.

Portable SED scripts should thus avoid relying on either behavior;

either use the <CODE>-n</CODE> option and explicitly print what you want,

or avoid use of the <CODE>p</CODE> command (and also the <CODE>p</CODE> flag to the

For those who want to write portable SED scripts,
|
||||
be aware that some implementations have been known to
|
||||
limit line lengths (for the pattern and hold spaces)
|
||||
to be no more than 4000 bytes.
|
||||
The POSIX.2 standard specifies that conforming SED
|
||||
implementations shall support at least 8192 byte line lengths.
|
||||
GNU SED has no built-in limit on line length;
|
||||
as long as SED can malloc() more (virtual) memory,
|
||||
it will allow lines as long as you care to feed it
|
||||
(or construct within it).
