Apologies that I am unable to reply in your native tongue, but I think I
can explain your issue:

You are insufficiently quoting your arguments, and happen to have a file
named 'a' in the current directory. Thus, you are experiencing shell
globbing.
$ mkdir example
$ cd example
$ echo [warning]
[warning]
$ touch a
$ echo [warning]
a
$ touch n
$ echo [warning]
a n
$ echo "[warning]"
[warning]
This is not a bug in bash, but in your script.
