addgnupghome account_1 account_2...account_n
If GnuPG is installed on a system with existing user accounts, it is sometimes required to populate the GnuPG home directory with existing files. Especially a trustlist.txt and a keybox with some initial certificates are often desired. This scripts help to do this by copying all files from /etc/skel/.gnupg to the home directories of the accounts given on the command line. It takes care not to overwrite existing GnuPG home directories.
addgnupghome is invoked by root as:
addgnupghome account1 account2 ... accountn
