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

$ mkdir example
$ cd example
$ echo [warning]
$ touch a
$ echo [warning]
$ touch n
$ echo [warning]
a n
$ echo "[warning]"

This is not a bug in bash, but in your script.
