find . -name "*" |xargs cp ????
這里 xargs cp 怎么區分cp源 和 cp目的
例如:想把 查詢到的文件 都copy到/home/users/中去
find . -name "*" | xargs cp /home/users/
cp命令在這里就變成:cp /home/users/ Find_file
默認從管道傳來的值是放在最后的 這樣的話原本想做cp源文件的值和目的目錄的參數就顛倒了
有辦法解決一下嗎?
xargs 沒有想-exec 那種 {} 的變量嗎?
find . -name "*" | xargs -i cp {} /home/users/
-i 和{} 什么關系?
-i 表示 find 傳遞給xargs的結果 由{}來代替

在Ubuntu (Ubuntu 12.04.4 LTS \n \l)上查到的結果:
-I replace-str
Replace occurrences of replace-str in the initial-arguments with names read from standard input. Also, unquoted blanks do not terminate input items; instead the separator is the new‐
line character. Implies -x and -L 1.
--replace[=replace-str]
-i[replace-str]
This option is a synonym for -Ireplace-str if replace-str is specified, and for -I{} otherwise. This option is deprecated; use -I instead.
