python - 如何将包含文件名和信息的文件分别拆分为多个文件？

Question

我有一个file.txt看起来像这样的（我删除了行以简化我的示例）：

PLXNA3                                                                                     ### <- filename1
Missense/nonsense : 13 mutations                                                           # <- header spaces
accession   codon_change    amino_acid_change                                              # <- column names tsv

ID31        GCC-GTC         Ala307Val                                                      # <- line tsv
NEDD4L                                                                                     ### <- filename2
Splicing : 1 mutation                                                                      # <- header spaces

ID51           IVS1 as G-A -16229                                                          # <-  line tsv

Small insertions : 3 mutations                                                             # <- header spaces

我想拆分此文件以获得 3 个不同的文件：

PLXNA3.txt

Missense/nonsense : 13 mutations                                                           # <- header spaces

OPHN1

OPHN1                                                                                      ### <- filename3
Small insertions : 3 mutations                                                             # <- header spaces

如何使用任何 linux 命令（如awkor ）来实现所需的输出python？

笔记：

• 文件名没有任何空格或制表符，但它们可能包括-.
• 标头包含空格。
• 行是制表符分隔的。
• 真正的分隔符应该是文件名，因为我可以有多个标题。

提前致谢。

Answer 1

awk 'NF==1{filename=$0 ".txt"};{print > filename}' file.txt

一个等效但更具高尔夫球性的选择是

awk 'NF==1{f=$0".txt"}{print>f}' file.txt
