每六行，我就在$1 1BGL->2BGL中添加一行。怎么做

我尝试过这样的事情，但我不知道下一步是什么：

#!/bin/bash
index=1
awk '{ for (i = 1; i <= NF; ++i) if (i = 6) index=index+1; print $1=($index)BGL  }' after_SOL.gro | tee after_SOL2.gro

到

第一种解决方案：不使用函数的简单解决方案

awk '
FNR==1{
  ++count
  value=count"BGL"
}
{
  $1=value
}
1
FNR%6==0{
  ++count
  value=count"BGL"
}
'  Input_file

说明：添加上述内容的详细说明

awk '                        ##Starting awk program from here.
function add_counter() {     ##Creating function named add_counter here.
  ++count                    ##increment value of count with 1.
  value=count"BGL"           ##Creating variable value whose value is count and string BGL here.
}
FNR==1{                      ##Checking condition if FNR==1 then do following.
  add_counter()              ##Calling function add_counter here.
}
{
  $1=value                   ##Assigning variable value to current 1st field of current line.
}
1                            ##Mentioning 1 will print edited/non-edited lines here.
FNR%6==0{                    ##Checking condition if FNR%6==0 then do following.
  add_counter()              ##Calling function add_counter here.
}
'  Input_file                ##Mentioning Input_file name here.

第二种解决方案：采用函数法：

awk '
function add_counter() {
  ++count
  value=count"BGL"
}
FNR==1{
  add_counter()
}
{
  $1=value
}
1
FNR%6==0{
  add_counter()
}
'  Input_file

另一种仅使用模运算的

awk

解决方案：

awk '{$1 = value ? value : $1} 1; NR%6 == 0{value = int(NR/6)+1 "BGL"}' file.csv |
column -t

column-t

用于获取表格数据，如果您不需要，可以跳过它。

谢谢。你在哪里学的awk。我找不到很好的课程。例如，我用0美元代替1美元谢谢。你在哪里学的awk。我找不到很好的课程。例如，我用$0而不是1来打印整行，我不知道我可以用“1”而不是$0$0 FNR%6==0{add_counter（）}`我不知道，为什么要检查FNR==1？你检查是否有一行，它停在文件的末尾？@Jakub，我从它的手册页学到了awk，为了解释，我相信我在我的帖子中添加了详细的解释，请检查一下，让我知道then@Jakub，我刚去了awk标签的SO页，拿到了这本书，你可以读这本书来学习awk
