Java sed: working with multiple lines
Got another sed question Smilie

My text block is

10002,9:12/123456789
10002,10:1
10002,11:1
10004,9:12/123456789
10004,10:1
I need to do the following:
If (and only if) the line starting with 10002,11 is followed by a line starting with 10004,9 , insert the line 10003,9 between the 2

Thus, my output should be

10002,11:1
10003,9
10004,9:12/123456789
10004,10:1
I tried
Quote:
sed '
/^10002,11/ {
N
/\n.*10004/ a\
10003,9:1
}'
but this gives me

10003,9
10004,10:1
(the order is not as i wanted it)

What am I doing wrong?

Thanks once again!

DESCRIPTION

       The  libpng  library  supports encoding, decoding, and various manipulations of the Portable Network Graphics (PNG) format image files. The
       libpng library uses the zlib(3) compression library.

EXTENDED DESCRIPTION

   Version Numbers
       Due to various miscommunications, unforeseen code incompatibilities and occasional factors outside the authors' control, version  numbering
       on  the	library  has not always been consistent and straightforward. The following table summarizes matters since version 0.89c, which was
       the first widely used release.

       *		       From this release forward, the png.h string is identical to the source version.

       #		       From this release forward, the shared library is 2.V, where V is the source code version except as noted.

       Henceforth, the source version will match the shared-library minor and patch numbers. The shared-library major version number will be  used
       for  changes  in  backward compatibility, as it is intended. The PNG_PNGLIB_VER macro, which is not used within libpng but is available for
       applications, is an unsigned integer of the form xyyzz corresponding to the source version x.y.z (leading zeros in y and z). Beta  versions
       were  given  the  previous  public  release  number  plus a letter, until version 1.0.6j. From then on, they were given the upcoming public
       release number plus "betaNN" or "rcN".
