searching and editing file contents
Can you please help me to edit parts of a file and write into a new file.
=====================================
Suppose I have a huge data dump in a file I need to search for a tag in that and cut few lines around that tag in the file. Is there a way to keep track of line numbers and operate on the file.
I can explain with example.
I have this file AAA
-----AAA------
Start:
name:1111
date:222
id:3333
address:12444
end
Start:
name:5555
date:3312
id:6666
address:qwds
end
Start:
name:7777
date:9090
id:4571
address:abc444
end
----------------
ID is unique for each start-end block in above file.
In above file, I need to search for a ID, say 4571 and just extract the block Start-End having details about id:4571
expected output is:
name:7777
date:9090
id:4571
address:abc444
can you please suggest how I can go about getting the necessary data from AAA given a ID as input?
