I'm doing server maintainence to a HP UX server and I have 2 files that someone need for an unknown reason. I was wondering If I can put this files on a memory stick, or is there someother way I have to copy it for them?

Easiest I can think of is use a script to email the files to yourself or to them, I guess that would depend on how big they are though.

There are quite a few threds on here dealing with that.

Have never tried using a USB disk on our HP-UX. We either send email attachment or ftp to/from them.

A couple of approaches:

use mailx to mail an attachment file to an email address available on a pc (don't mail to your unix account)
[see this link, and there are many more mentions of mailx on this forum -- Sending Attachments Through mailx

use an ftp program to transfer the file
[see this link for ftp and much more -- transfering files unix to pc

I use smb mount to my pc and so can copy it after...
