This article details how to change the home directory for PGP Command Line when using AIX, Solaris, Linux, Fedora Core, or HP-UX.
Changing the Home Directory for PGP Command Line
The home directory is where PGP Command Line stores the files that it creates and uses; for example, keyring files. By default, the PGP Command Line installer creates the PGP Command Line home directory at $HOME/.pgp. If this directory does not exist, it will be created.
For example, if the value of $HOME for user "alice" is /usr/home/alice, PGP Command Line will attempt to create /usr/home/alice/.pgp.
The PGP Command Line installer will not try to create any other part of the directory listed in the $HOME variable, only .pgp.
If you want the home directory changed on a permanent basis, you will need to create the $PGP_HOME_DIR environment variable and specify the path of the desired home directory.
To change the home directory for a command
pgp --list-keys --home-dir other-pgp-files/
This changes the home directory for this command to "other-pgp-files/"
