The passwd Command

This will create a file named .wrpasswd in the user's home directory, which is an encrypted file containing the user name and password to the program distribution repository. The user name and password are provided by Whiteley Research upon program or maintenance extension purchase, and must be supplied in order to access the distribution point for updates. This command prompts the user for the user name and password, and writes the .wrpasswd file. This needs to be done only once.

With the .wrpasswd file present, WRspice will check for the availability of updates when the program starts, and alert the user if an update is available (this can be prevented by setting the nocheckupdate variable in an initialization file).

The .wrpasswd file is also necessary for the wrupdate command to function.
