男人 写了: xargs - build and execute command lines from standard input
----------男人 写了:The args are read and concatenated together into a single com-
mand. This command is then read and executed by the shell, and
its exit status is returned as the value of eval.
从字面上xargs,和eval没有多大区别,但细看xargs,太复杂了,愣是不会用,还请高手指教。
拜过。
