我的样本文件如下:

H343423     Something1          Something2                                                
C343423              0   
A23423432     asdfasdf sdfs 
#2342323

我有以下条例:

if (line =~ /^[HC]d+s/) != nil 
  puts line
end

基本上,我想读一下从H或C开始,然后是编号,我想在遇到空间时停止阅读(我想读一个字)。

产出一:

H343423
C343423

产出:

H343423     Something1          Something2                                                
C343423              0   

因此,它贯穿整个轨道,但我只想在一读之后停止。

任何帮助?

问题回答
if (line =~ /^([HC]d+)/)
  puts $1
end

For more info, see

如果您不希望使用方括号,则对相应的项目金额和计划有特殊变量;

如下:

if line =~ /^[HC]d+/
  puts $&
end
