Unix extract lines in between 2 lines and store them in respective files

Question

I have a file like below in file allreport.txt:

11:22:33:456        Script started                  Running: first_script
11:22:34:456        GetData - Read                  Read 12 Bytes
11:22:34:456        SetData - Write                 Write 12 Bytes
11:32:33:456        Script started                  Running: second_script
11:32:34:456        GetData - Read                  Read 12 Bytes
11:32:34:456        SetData - Write                 Write 12 Bytes
11:42:33:456        Script started                  Running: third_script
11:42:34:456        GetData - Read                  Read 12 Bytes
11:42:34:456        SetData - Write                 Write 12 Bytes
11:52:33:456        Script started                  Running: fourth_script

My requirement is that I need to extract the '....' lines which are in between '*scripts'. I tried something like below:

grep 'Running:' allreport.txt | sed 's/[^ ]* //' | cut -d":" -f2 | tr '\n' ' ' | awk -v col=1 '/$col/,/$($col+1)/ allreport.txt  > $col'

But after execution of the command I see no output and no result files also created?

How can I achieve the same - the expected output is to have files like first_script, second_script and so on and each of the files contains logs of its run - example first_script should have below lines only:

11:22:34:456        GetData - Read                  Read 12 Bytes
11:22:34:456        SetData - Write                 Write 12 Bytes

Similarly second_script should have below lines and so on:

11:32:34:456        GetData - Read                  Read 12 Bytes
11:32:34:456        SetData - Write                 Write 12 Bytes

Answer 1

With your shown samples only, please try following. As an output it will create 3 files named first_script, second_script and third_script with shown samples.

awk -F': ' '/Running/{close(outFile);outFile=$2;next} {print > (outFile)}' Input_file

Explanation: Simple explanation would be, making field separator as : then checking if line has Running in it then set output file name as 2nd field. If line is NOT having Running then print that line into output file. Also making sure to close the output file in backend to avoid "too many opened files error" here.

Answer 2

You may try this awk also:

awk '$(NF-1) == "Running:" {close(fn); fn = $NF; next} {print > fn}' file
