4.9 Environment variables

A few of the compile-time defaults may be overridden at run-time by using environment variables. The following variables are supported.

• SHISHI_CONFIG Specify the location of the default system configuration file. Used by the Shishi library. If not specified, the default is specified at compile-time and is usually $prefix/etc/shishi.conf.
• SHISHI_HOME Specify the user specific directory for configuration files, ticket cache, etc. Used by the Shishi library. If not specified, it is computed as $HOME/.shishi.
• SHISHI_USER Specify the default principal user name. Used by the Shishi library. If not specified, it is taken from the environment variable USER.
• SHISHI_TICKETS Specify the file name of the ticket cache. Used by the Shishi library. If not specified, it will be $SHISHI_HOME/tickets, or $HOME/.shishi/tickets if $SHISHI_HOME is not specified.
