Transpose a column to a line after detecting a pattern - awk

Question

I have this text file format:
01 contig00041 1 878 + YP_003990830.1 metalloendopeptidase, glycoprotease family Geobacillus sp. Y4.1MC1 100.00 291 1 291 47 337 0.0 592 #line 1
01 contig00041 1241 3117 - YP_002948419.1 ABC transporter Geobacillus sp. WCH70 84.94 #line 2
37.31 624 #line 3
260 1 #line 4
321 624 #line 5
532 23 #line 6
12 644 #line 7
270 0.0 #line 8
3e-37 1046 #line 9
154 #line 10
I have to detect a line containing 8 columns (line 2), and transpose the second column of the followning seven lines (lines 3 - 9) to the end of the 8-column line. And finally, exclude line 10. This pattern repeats along a large text file, but it is not frequent (30 time, in a file of 2000 lines). Is it possible doing it using awk?
The edited text file must look like the following text:
01 contig00041 1 878 + YP_003990830.1 metalloendopeptidase, glycoprotease family Geobacillus sp. Y4.1MC1 100.00 291 1 291 47 337 0.0 592 #line 1
01 contig00041 1241 3117 - YP_002948419.1 ABC transporter Geobacillus sp. WCH70 84.94 624 1 624 23 644 0.0 1046 #line 2
Thank you very much in advance.

Answer 1

awk 'NF == 12 { t = $0; for (i = 1; i <= 7; ++i) { r = getline; if (r < 1) break; t = t "\t" $2; } print t; next; } NF > 12' temp.txt
Output:
01 contig00041 1 878 + YP_003990830.1 metalloendopeptidase, glycoprotease family Geobacillus sp. Y4.1MC1 100.00 291 1 291 47 337 0.0 592
01 contig00041 1241 3117 - YP_002948419.1 ABC transporter Geobacillus sp. WCH70 84.94 624 1 624 23 644 0.0 1046
It would automatically print lines having more than 12 fields.
If it detects lines having 12 fields, concatenate second column of other 7 lines with it and print.
Ignore any other line.

Answer 2

edited to only add the second column of the lines with two columns.
I think this does what you want:
awk 'NF >= 8 { a[++i] = $0 } NF == 2 { a[i] = a[i] " " $2 } END { for (j = 1; j <= i; ++j) print a[j] }' file
For lines with more than 8 columns, add a new element to the array a. If the line has 2 columns, append the contents to the current array element. Once the whole file has been processed, go through the array and print all of the lines.
Output:
01 contig00041 1 878 + YP_003990830.1 metalloendopeptidase, glycoprotease family Geobacillus sp. Y4.1MC1 100.00 291 1 291 47 337 0.0 592
