如何在 linux 中重新格式化 Kegg 映射器輸出？

我需要重新格式化kegg reconstruct pathway輸出，我在file1中有這樣的東西：

00550 Peptidoglycan biosynthesis (2)

K01000

K02563

00511 Other glycan degradation (8) K01190   K01191

K01192

K01201

K01227

K12309

我在file2中需要一些類似的東西：

00550 Peptidoglycan biosynthesis (2)   K01000   K02563
00511 Other glycan degradation (6)   K01190   K01191   K01192   K01201   K01227   K12309

我如何在 linux 或 python 中重新格式化它？

謝謝

這會讓你走多遠：

awk '
!NF             {next                                                   # don"t process empty lines
               }
/^[0-9]+ /      {sub (/\([0-9]*\)/, "(" CNT ")", PRT)                   # for the "glycan" lines (leading numerical)
                                                                       # correct the count in parentheses
                if (PRT) print PRT                                     # print the PRT buffer (NOT first line when empty)
                PRT = ""                                               # empty it after print
                CNT = gsub (/K[0-9]*/, "&") - 1                        # get this line"s "K..." count, corr.for later incr.
               }
               {PRT = sprintf ("%s%s%s", PRT, PRT?" ":"", $0)          # append this line to buffer
                CNT++                                                  # increment "K..." count
               }
END             {sub (/\([0-9]*\)/, "(" CNT ")", PRT)                   # see above
                print PRT
               }
