输入是一个制表符分隔的文件(这里是空格,但无论如何):
Sample1 ACGGGGCGCAGCAGGCGCGA text other122
something ABCDSDDADASDASDSAD hjas 23823sss
ahsdksads AHJHJDHSJHJDALKDLK hello world
我想要做的是在第一列之后添加一列选项卡。所以基本上:
Sample1<TAB><TAB>ACGGGGCGCAGCAGGCGCGA<TAB>text<TAB>other122
something<TAB><TAB>ABCDSDDADASDASDSAD<TAB>hjas<TAB>23823sss
ahsdksads<TAB><TAB>AHJHJDHSJHJDALKDLK<TAB>hello<TAB>world
sed/awk 首选,但无论如何..
