根据使用awk或bash提交的tbname添加行号

Question

输入文件

tbname id department 
xyz    20 cic 
xyz    21 csp 
xyz    22 cpz 
abc    25 cis 
abc    26 cta 
abc    27 tec 

输出应该是这样的..

tbname id department 
xyz    20 cic          1 
xyz    21 csp          2 
xyz    22 cpz          3 
abc    25 cis          1 
abc    26 cta          2 
abc    27 tec          3

所有字段均由标签分隔

Answer 1

在awk中真的微不足道：

$ awk 'NR>1{$0=$0"\t"++a[$1]}1' file
tbname id department 
xyz    20 cic   1
xyz    21 csp   2
xyz    22 cpz   3
abc    25 cis   1
abc    26 cta   2
abc    27 tec   3
