DESCRIPTION
Opera is a graphical Web browser available on several platforms. The desktop version described in this manual
page runs on GNU/Linux, FreeBSD, and Solaris. Versions for Macintosh and Windows are also available.
COMMAND LINE OPTIONS
These support both double and single dash as prefix. Several other options are also supported, notably including
many generic X Toolkit options; see --help output for details.
--personaldir path
--pd path

--remote command

debug).
--nowin
Do not open any document windows.
--version
Display version information and exit.
-h , --help

REMOTE COMMANDS
Since commands include parentheses, which have special meaning to the shell, it is important to enclose remote
commands in quotes, like --remote 'openURL()' so as to prevent the shell from interpreting the parentheses. In
the following, destination is one of new-window for a new window, new-page for a new page (or tab) or background-
page for a (new) background page (opened in an inactive new tab).
openURL()
Open "Go to" dialog box prompting for input.

FILES AND DIRECTORIES
/usr/bin/opera
Standard installation location for Opera driver script; configures environment and invokes the binary.
/usr/lib/opera/
Installation directory for Opera binaries, in version-specific sub-directories, with a separate plugins/
sub-directory for plugins.
/usr/share/opera/
Opera shared resource directory. Contains assorted data files.
/etc/opera6rc
Default settings for Opera configurations; may be overridden by the opera6.ini in a user's personal con-
figuration directory.
/etc/opera6rc.fixed
System settings for Opera configurations; cannot be overridden by users.
~/.opera/
The default personal configuration directory.
CONFIGURATION DIRECTORY
Private data for each user is stored in a personal configuration directory. By default this is ~/.opera/ but you
can override this by setting OPERA_PERSONALDIR (for example in your login shell's standard configuration file) to
a location of your choosing; or by passing a chosen directory with the --personaldir command-line option. For
the most part it is best to access the files in this directory via the preference and appearance dialogs -
accessed either from the Tools menu of the Opera user interface or via a keyboard shortcut: type Alt+P for the
main preferences dialog, Shift+F12 for the appearance dialog or simply F12 for a menu of the more commonly set
basic preferences from each. (You can control Opera entirely from the keyboard, including any of these dialogs;
to dismiss a dialog, use the Esc key.)
Most files in the directory have names which express their functions. Many of them have backups saved in *.bak
files. The file opera6.ini in this directory records most user preferences. Entries in it can override the
locations of some of the other files; this description relates each to its default location. A fuller account of
the opera6.ini file may be found at http://www.opera.com/support/usingopera/operaini/. Bookmarks are recorded in
opera6.adr, and global browsing history is recorded in global.dat; browsing histories for individual tabs are a
part of the session state saved as files in sessions/. In this sub-directory, the state of the current session
is saved in autosave.win; other sessions may be saved (see the Sessions sub-menu of the main File menu) to other
files in this directory. It is prudent to save such a named session before starting up Opera with a radically
new version (especially if it is a beta release).
ENVIRONMENT VARIABLES
OPERA_PERSONALDIR Override default personal configuration directory
OPERA_STRICT_FILE_PERMISSIONS Use owner-only permissions for all files created (as if by umask 077) if set to
YES, TRUE (case insensitively matched) or 1. Otherwise honour umask setting in the normal way.
