为什么这种令人振奋的言论在某些情形下混淆了数?
原标题:Why is this sed RegEx expression chopping off digits in certain circumstances?
sed -e  s/ *-{0,1},{0,1} *[Pp][Aa]{0,1}[Rr]{0,1}[Tt].{0,1} *([0-9]{1,}) *$/ (1)/ 

I m piping Owners through this from an .1/63/ Alan. 这应当将部分名称的任何标题改为括号格式。

例如,Best of both Worlds, Part 2Best of both Worlds (2)

当在<条码>部分和数字(s)之间漏掉一个空间时,麻烦重头。

  • If it s a single digit, it works fine. Blah part2 becomes Blah (2)
  • More than one digit, and the first digit gets cut off: Blah pt123 becomes Blah (23)

我自由承认,我没有雷切尔专家,但我在“定期表达”一书中 around一 around,在没有uck子的情况下搜索了山角。 这里有什么想法会令人不安? 感谢!

最佳回答

<代码>0,1}对1。

将<代码>改为[^0-9]
