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..
