我有一条线：
Jon Favreau,Stan Lee,Justin Theroux,Robert Downey Jr. (Tony Stark) Gwyneth Paltrow (Pepper Potts) Don Cheadle (James Rhodes)
我想用逗号分割行,并用该结果括起来：
Jon Favreau Stan Lee Justin Theroux Robert Downey Jr. (Tony Stark) Gwyneth Paltrow (Pepper Potts) Don Cheadle (James Rhodes)
编辑：特殊情况
线路：Jon Favreau,Robert Downey(Jr.)(Tony Stark)Gwyneth Paltrow(Pepper Potts)Don Cheadle(James Rhodes)
与世界(Jr.)在brakets.输出：
Jon Favreau Stan Lee Justin Theroux Robert Downey (Jr.) (Tony Stark) Gwyneth Paltrow (Pepper Potts) Don Cheadle (James Rhodes)
解决方法
首先在每个之后添加一个逗号然后拆分(并丢弃)逗号：
perl -e '$_="Jon Favreau,...";s/\)/\),/g;split ",";foreach (@_) {s/^\ //;print "$_\n"}'
产量：
Jon Favreau Stan Lee Justin Theroux Robert Downey Jr. (Tony Stark) Gwyneth Paltrow (Pepper Potts) Don Cheadle (James Rhodes)
