bash,Ksh 相同的Bug???

twf_cc

剛在網上看到有人問這個是不是 Ksh 的 bug
$ [ skdfjh -ot /etc/group ] && echo hi
hi
$

But "man ksh" says:

  file1 -ot file2
         True, if file1 exists and is older than file2.

But file1 does not exist!

bash 3 一樣啊...

[victor@localhost ~]$ echo $0
bash
[victor@localhost ~]$ [ skdfjh -ot /etc/shells ] && echo hi
hi
[victor@localhost ~]$

ash 沒問題...

一梦如是

       file1 -nt file2
              True if file1 is newer (according to modification date)  than
              file2, or if file1 exists and file2 does not.
       file1 -ot file2
              True  if  file1  is  older than file2, or if file2 exists and
              file1 does not.
