opera - Fast and secure web browser and Internet suite
Opera is a graphical Web browser available on several platforms. The desktop
version described in this manual page runs on GNU/Linux and FreeBSD. Versions
for Windows and MacOS X are also available.
These support both double and single dash as prefix. Several other options are

- Do not open any document windows.
- Display version information and exit.
- -h, --help
- Print option summary and exit.
Since commands include parentheses, which have special meaning to the shell, it
is important to enclose remote commands in quotes, like --remote
so as to prevent the shell from interpreting the parentheses.

- System settings for Opera configurations; cannot be overridden by
- The default personal configuration directory.
Private data for each user is stored in a personal configuration directory. By
default this is ~/.linux-opera
but you can override this by setting
(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
main preferences dialog, Shift
for the appearance dialog or
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
Most files in the directory have names which express their functions. Many of
them have backups saved in *.bak
files. The file operaprefs.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 operaprefs.ini

; 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).
- Override default personal configuration directory
- 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.
- Override the operating system name. If set, Opera will use this value as
part of the User Agent string instead of trying to detect the operating
