It is usually run interactively without arguments. It +also supports a batch mode where all the options can be specified +via the command-line. + +For upgrading BackupPC you need to make sure that BackupPC is not +running prior to running BackupPC. + +Typically configure.pl needs to run as the super user (root). + +=head1 OPTIONS + +=over 8 + +=item B<--batch> + +Run configure.pl in batch mode. configure.pl will run without +prompting the user. The other command-line options are used +to specify the settings that the user is usually prompted for. + +=item B<--bin-path PROG=PATH> + +Specify the path for various external programs that BackupPC +uses. Several --bin-path options may be specified. configure.pl +usually finds sensible defaults based on searching the PATH. +The format is: + + --bin-path PROG=PATH + +where PROG is one of perl, tar, smbclient, nmblookup, rsync, ping, +df, ssh, sendmail, hostname, split, par2, cat, gzip, bzip2 and +PATH is that full path to that program. + +Examples + + --bin-path cat=/bin/cat --bin-path bzip2=/home/user/bzip2 + +=item B<--config-path CONFIG_PATH> + +Path to the existing config.pl configuration file for BackupPC. +This option should be specified for batch upgrades to an +existing installation. The option should be omitted when +doing a batch new install. + +=item B<--cgi-dir CGI_DIR> + +Path to Apache's cgi-bin directory where the BackupPC_Admin +script will be installed. This option only needs to be +specified for a batch new install. + +=item B<--data-dir DATA_DIR> + +Path to the BackupPC data directory. This is where all the backup +data is stored, and it should be on a large file system. This option +only needs to be specified for a batch new install. + +Example: + + --data-dir /data/BackupPC + +=item B<--dest-dir DEST_DIR> + +An optional prefix to apply to all installation directories. +Usually this is not needed, but certain auto-installers like +to stage an install in a temporary directory, and then copy +the files to their real destination. This option can be used +to specify the temporary directory prefix. Note that if you +specify this option, BackupPC won't run correctly if you try +to run it from below the --dest-dir directory, since all the +paths are set assuming BackupPC is installed in the intended +final locations. + +=item B<--help|?> + +Print a brief help message and exits. + +=item B<--hostname HOSTNAME> + +Host name (this machine's name) on which BackupPC is being installed. +This option only needs to be specified for a batch new install. + +=item B<--html-dir HTML_DIR> + +Path to an Apache html directory where various BackupPC image files +and the CSS files will be installed. This is typically a directory +below Apache's DocumentRoot directory. This option only needs to be +specified for a batch new install. + +Example: + + --html-dir /usr/local/apache/htdocs/BackupPC + +=item B<--html-dir-url URL> + +The URL (without http://hostname) required to access the BackupPC html +directory specified with the --html-dir option. This option only needs +to be specified for a batch new install. + +Example: + + --html-dir-url /BackupPC + +=item B<--install-dir INSTALL_DIR> + +Installation directory for BackupPC scripts, libraries, and +documentation. This option only needs to be specified for a +batch new install. + +Example: + + --install-dir /usr/local/BackupPC + +=item B<--man> + +Prints the manual page and exits. + +=item B<--uid-ignore> + +configure.pl verifies that the script is being run as the super user +(root). Without the --uid-ignore option, in batch mode the script will +exit with an error if not run as the super user, and in interactive mode +the user will be prompted. Specifying this option will cause the script +to continue even if the user id is not root. + +=head1 EXAMPLES + +For a standard interactive install, run without arguments: + + configure.pl + +For a batch new install you need to specify answers to all the +questions that are normally prompted: + + configure.pl \ + --batch \ + --cgi-dir /var/www/cgi-bin/BackupPC \ + --data-dir /data/BackupPC \ + --hostname myHost \ + --html-dir /var/www/html/BackupPC \ + --html-dir-url /BackupPC \ + --install-dir /usr/local/BackupPC + +For a batch upgrade, you only need to specify the path to the +configuration file: + + configure.pl --batch --config-path /data/BackupPC/conf/config.pl + +=head1 AUTHOR + +Craig Barratt + +=head1 COPYRIGHT + +Copyright (C) 2001-2004 Craig Barratt. + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. + +=cut
