My mean is test.txt in /tmp,
how to set the file permission
or other ways to restrict ftp user to catch the test.txt file.

I will assume you want the file to be visible only to one user.

chown user:group filename
chmod 700 filename

These two command will make give the owner full permissions on it, when connected via ftp.

I hope I guessed your question correctly, if not, clarify.

For example: /tmp/test.txt
the file permission is r--r--r--. When user using ftp from client,I don't want to test.txt can get from ftp. Is it possible to do this in HPUX?

There are many things to consider to properly restrict ftp access. I strongly suggest you study the "how-to" guides found at this web site.

To say it another way,....

You do not want any user to be able to get "test.txt" using ftp?

Use the file /etc/ftpd/ftpaccess, and specify an option of "noretrieve" within it for the full file name.

To activate this, edit the /etc/inetd.conf file and specify options of "-a" on the "ftpd" line. Stop and restart internet services using /sbin/init.d/inetd.

I would suggest trying this on a test box first to validate it before rolling it out.

Alternatively, there are a lot of excellent FTP Servers out there that have many configuration options.
