OPERA(1)                                                              OPERA(1)



NAME
       opera - a standards-compliant graphical Web browser

SYNOPSIS
       opera [options] [URL...]

DESCRIPTION
       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 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
              Use  path  as  personal  configuration directory (ignore default
              location).

       --remote command
              Send command to an existing Opera window.  See "REMOTE COMMANDS"
              section below.

       --nomail
              Start  Opera  without internal e-mail client (also disables chat
              and newsfeeds).

       --nosession
              Do not open a saved window session or homepage.

       --noshape
              Suppress X shape-extension  for  widgets,  to  make  their  full
              underlying rectangle visible (useful for debug).

       --nowin
              Do not open any document windows.

       --version
              Display version information and exit.

       -h, --help
              Print option summary and exit.

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.

       openURL(URL)
              Open URL in active window.

       openURL(URL,destination)
              open URL in destination window, tab or background.

       openFile(destination)
              Open file selector in destination window or page (background not
              supported).

       openM2(new-window)
              Open Opera mail client list view in a new window.

       openComposer(new-window)
              Open Opera mail composer in a new window.

       addBookmark(URL)
              Add URL to bookmark list.

       raise()
              Raises the Opera window.

       lower()
              Lowers the Opera window.

FILES AND DIRECTORIES
       /usr/lib/opera
              Installation directory for Opera binaries, with a separate plug‐
              ins sub-directory for plugins.

       /usr/share/opera
              Opera shared resource directory.  Contains assorted data files.

       /etc/operaprefs_default.ini
              Default settings for Opera configurations; may be overridden  by
              the operaprefs.ini in a user's personal configuration directory.

       /etc/operaprefs_fixed.ini
              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 direc‐
       tory.  By default this is ~/.opera but you can override this by setting
       OPERA_PERSONALDIR (for example in your login shell's standard  configu‐
       ration  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 prefer‐
       ence 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  oper‐
       aprefs.ini in this directory records most user preferences.  Entries in
       it can override the locations of some of the other files; this descrip‐
       tion  relates  each  to  its default location.  A fuller account of the
       operaprefs.ini file may be found at http://www.opera.com/support/using‐
       opera/operaini/.   Bookmarks  are recorded in bookmarks.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 ses‐
       sions.  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.

       OPERA_SYSTEM_UNAME
              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 system.
