shell脚本的$@和$*

@ 和 @和 @和*的区别

#!/bin/bash# $@ and $* my_fun (){echo "$#"}echo 'the number of parameter in "$@"   is'    $(my_fun  "$@")
echo 'the number of parameter in "$*"     is'     $(my_fun  "$*")echo 'the number of parameter in $@      is'    $(my_fun  $@)
echo 'the number of parameter in $*        is'     $(my_fun  $*)

[lf@x201t ~]$ sh a.sh p1 "p2 p3" p4the number of parameter in "$@" is 3  
the number of parameter in "$*" is 1the number of parameter in $@ is 4
the number of parameter in $* is 4

看出区别了吗？关键 $@ 靠谱一点
