Java Grep the word from pattern line and update in subsequent lines till next pattern line reached
Hi,

I have got the below requirement. please suggest.

I have a file like,

Code:
Processing Item is: [08765]
/data/ing/cfg2/abc.txt
/data/ing/cfg3/bgc.txt
Processing Item is: [0975398]
/data/cmd/for2/ght.txt
/data/kernal/config.klgt.txt

I want to process the above file to get the output file like,

Code:
08765:/data/ing/cfg2/abc.txt
08765:/data/ing/cfg3/bgc.txt
0975398:/data/cmd/for2/ght.txt
0975398:/data/kernal/config.klgt.txt

i.e, here the pattern line is the one starts with "Processing Item is:" which has the string/number in square bracket at the end. i want to grep the string/number and put it in the next few lines until next pattern line starts. once the next pattern line comes, grep the number/string from that new pattern line and add it to the below lines until next pattern line is reached and so on..

fmt

fmt(1)							      General Commands Manual							    fmt(1)

NAME

       fmt - format text

SYNOPSIS

       width] [file...]

DESCRIPTION

       The  command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in
       the width option.  The default width is 72.  concatenates the arguments.  If none are given, formats text from the standard input.

       Blank lines are preserved in the output, as is the spacing between words.  does not fill lines beginning with a	period	for  compatibility
       with Nor does it fill lines starting with

       Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used).

       can also be used as an in-line text filter for the command:

       reformats the text between the cursor location and the end of the paragraph.

   Options
       recognizes the following options:

	      Crown margin mode.
		    Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that
		    of the second line.  This is useful for tagged paragraphs.

	      Split lines only.
		    Do not join short lines to form longer ones.  This prevents sample lines of code, and other such "formatted" text, from  being
		    unduly combined.

	      Fill output lines to up to
		    width columns.

WARNINGS

       The width option is acceptable for BSD compatibility, but it may go away in future releases.
