To change the behaviour, you can either edit this variable or set `gnus-uu-user-view-rules' to something useful.

The first string is a regular expression. If the file name matches this regular expression, the command in the second string is executed with the file as an argument. If the command string contains \"%s\", the file name will be inserted at that point in the command string. If there's no \"%s\" in the command string, the file name will be appended to the command string before executing. There are several user variables to tailor the behaviour of gnus-uu to your needs.
