$uname -a

$echo $0
   -bash
$cd test
$ls
$ls *             *<== at first,no file/directory under current work directory*
ls: cAnnot access *: No such file or directory
$mkdir abc        *<== create a new directory "abc"*
$ls *             *<== output of "ls *" is empty but directory "abc" has been created.*
$mkdir abcd       *<== create the second directory "abcd"*
$ls *             *<== at this point,all the directories("abc" and "abcd") are displayed.*
abc:

abcd:

任何人都可以解释为什么在创建目录“abc”后@L_696_0@“ls *”为空？谢谢.
