It is because the * gets interpreted and expanded by the shell to the content of the current directory. Just go into a directory and issue:
Code:
var=*
echo $var

If you put quotes around $var, you just get the asterisk

Hi, another question.
Is there any posibility that this error only happens in some versions of the operation system?
I received that script from a friend of mine, and he said that there were no such error in his computer. I am using Ubuntu 10, and he is using Ubuntu 9.

No not really. What could have happened is that his input files simply did not have asterisks in them. It could also be that he set globbing to off (i.e. no asterisk expansion) in his shell (not very likely) It could also be that he always executed the script from an empty directory, in which case the asterisk would also not get expanded. To illustrate:
Code:
$ mkdir test
$ cd test
$ echo *
*
