关于xargs cp中,如何确定拷贝的源和目的 (copied)
find . -name "*" |xargs cp ????
这里 xargs cp 怎么区分cp源 和 cp目的
例如:想把 查询到的文件 都copy到/home/users/中去
find . -name "*" | xargs cp /home/users/
cp命令在这里就变成:cp /home/users/ Find_file
默认从管道传来的值是放在最后的 这样的话原本想做cp源文件的值和目的目录的参数就颠倒了
有办法解决一下吗?
xargs 没有想-exec 那种 {} 的变量吗?
find . -name "*" | xargs -i cp {} /home/users/
-i 和{} 什么关系?
-i 表示 find 传递给xargs的结果 由{}来代替

在Ubuntu (Ubuntu 12.04.4 LTS \n \l)上查到的结果:
-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.
