我最近正在阅读Linux 手册页xargs，似乎该-i选项已被弃用。从文档中引用：
-i[replace-str], --replace[=replace-str]
This option is a synonym for -Ireplace-str if replace-str is
specified. If the replace-str argument is missing, the effect
is the same as -I{}. This option is deprecated; use -I
instead.
只是好奇，为什么它被弃用了？使用更冗长的-I{}语法的原因是什么？
