I am new to linux searching and would appreciate any help that can be provided. I would like to be able to perform a command line to execute my search.
I have a text file with multiple log data, I would like to search for 'Keyword-1' in a line, and when it finds the line, to search within that line for another keyword such as 'engine-1'. Then extract the section from the start of 'engine-1' until it reaches a different engine such as 'engine-2'. I would like all 'engine-1' section extracted, that includes all lines between the start and end of 'engine-1'. The end of 'engine-1' is defined by reaching any other number such as 'engine-2' or 'engine-xx'.
Note, not all lines contain the word engine, but I still want to extract the 'Data' between 'engine-1' start and 'engine-1' end.
Then moved on to the next section in the file and repeat the process by searching for keyword-1 first and finding out engine it uses, and extracted the start/end section of the new different engine. The link between all sections would be 'keyword-1'
The text file looks like this:
Data engine-1
Data engine-1
Data
Data
Data engine-1 **keyword-1**
Data engine-1
Data engine-2
Data engine-2
Data
Data
Data engine-2
Data engine-2
Data engine-3
Data engine-3
Data
Data
Data engine-3 **keyword-1**
Data engine-3
Data engine-1
Data engine-1
Data
Data
Data engine-1
Result should look like this after extraction:
Data engine-1
Data engine-1
Data
Data
Data engine-1 **keyword-1**
Data engine-1
Data engine-3
Data engine-3
Data
Data
Data engine-3 **keyword-1**
Data engine-3
Any help would be greatly appreciated.
Thanks
