Xargs
為什麼不推薦使用 xargs -i 選項?
我最近正在閱讀Linux 手冊頁
xargs
,看來該-i
選項已被棄用。從文件中引用:-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,為什麼它被棄用了?使用更冗長的
-I{}
語法的原因是什麼?
muru是對的,如果你檢查
findutil
changelog @line 1645
- 2004-12-05 版本 4.2.9 的主要變化
xargs
現在支持 POSIX 選項-E
和. 這些是現有選項和的同義詞,但後三個現在已棄用。-I``-L``-e``-i``-l
頁面中也有解釋
man
,請參閱-l
選項:
The -l option is deprecated since the POSIX standard specifies -L instead.
並且進一步向下:
The -l and -i options appear in the 1997 version of the POSIX standard, but do not appear in the 2004 version of the standard. Therefore you should use -L and -I instead, respectively.
