How to share Opera settings between Windows & Linux?

Wednesday, 21. February 2007, 03:56:23

, , , ...

To share profile/settings between Windows & Linux, you should have Windows FAT32 partition and it should be mounted (preferably automatically) in Linux with read write access.

Backup both profile & mail directories in Windows & Linux.

In Windows

Method 1

Install another copy of Opera in FAT32 partition with Individual Opera profiles for each user on this computer option unchecked. Copy settings from old Opera to new Opera.

Method 2

Using NTFS junction point (you should have NTFS in system drive)

Move profile & mail directories to FAT32 partition and create junction point from old profile & mail location to new profile & mail location using Junction Link Magic or command line tool Junction. See observed effects of junction point.

Method 3

  1. Move profile & mail directories to FAT32 partition except profile\opera6.ini file and change all absolute file paths to reflect the new location in profile\opera6.ini, profile\widgets\widgets.dat & mail\accounts.ini.
  2. Move profile & mail directories to FAT32 partition, change all absolute file paths to reflect the new location in profile\opera6.ini, profile\widgets\widgets.dat & mail\accounts.ini and run Opera with command line option /settings. Example: C:\Program Files\Opera\Opera.exe /settings D:\Opera\profile\opera6.ini

In Linux

Method 1

Change all file paths to reflect FAT32 partition location in opera6.ini.

Method 2

Using symbolic link (AKA symlink or soft link)

Symbolic links in Linux
Symbolic links in Linux

Move all files from ~./opera except cookies4.dat, opera6.ini, pluginpath.ini & vlink4.dat to some folder. Create a script file with the following code, change /windows/Opera/profile with path to Opera profile in FAT32 partition, set executable permission and run.

#!/bin/bash -

if [ ! -e ~/.opera ]; then mkdir ~/.opera; fi
cd ~/.opera

ln -s /windows/Opera/mail mail
ln -s /windows/Opera/profile/cache4 cache4
ln -s /windows/Opera/profile/cacheOp cacheOp
ln -s /windows/Opera/profile/images images
ln -s /windows/Opera/profile/keyboard keyboard
ln -s /windows/Opera/profile/menu menu
ln -s /windows/Opera/profile/mouse mouse
ln -s /windows/Opera/profile/sessions sessions
ln -s /windows/Opera/profile/skin skin
ln -s /windows/Opera/profile/styles styles
ln -s /windows/Opera/profile/toolbar toolbar
ln -s /windows/Opera/profile/userjs userjs
ln -s /windows/Opera/profile/widgets widgets
ln -s /windows/Opera/profile/contacts.adr contacts.adr
#ln -s /windows/Opera/profile/cookies4.dat cookies4.dat
ln -s /windows/Opera/profile/download.dat download.dat
ln -s /windows/Opera/profile/global.dat global.dat
ln -s /windows/Opera/profile/notes.adr notes.adr
ln -s /windows/Opera/profile/opcacrt6.dat opcacrt6.dat
ln -s /windows/Opera/profile/opera.dir opera.dir
ln -s /windows/Opera/profile/opera6.adr opera6.adr
ln -s /windows/Opera/profile/oprand.dat oprand.dat
ln -s /windows/Opera/profile/opssl6.dat opssl6.dat
ln -s /windows/Opera/profile/override.ini override.ini
ln -s /windows/Opera/profile/search.ini search.ini
ln -s /windows/Opera/profile/speeddial.ini speeddial.ini
ln -s /windows/Opera/profile/urlfilter.ini urlfilter.ini
#ln -s /windows/Opera/profile/vlink4.dat vlink4.dat
ln -s /windows/Opera/profile/wand.dat wand.dat
ln -s /windows/Opera/profile/widgets.adr widgets.adr
exit 0
Even if you create symbolic link for cookies4.dat & vlink.dat, these will be replaced by files when you close Opera.

Warning: There is no security option in FAT32. So, anyone can access your profile in FAT32 partition if they have account in Windows.

Opera backup using RAR for Linux

Create a file opera-backup.sh in your home, add the following and set Execute permission.

#!/bin/bash -
# Opera backup using WinRAR command line
#
# To restore files from backup use the following commands
# cd ~
# unrar x <path-to-archive>
# Example : unrar x /backup/opera-backup-061010-144215.rar
#
echo -e "\nOpera backup using WinRAR command line\n"
cd ~
rar a -hppassword -m5 -r -agYYMMDD-HHMMSS opera-backup- @opera-backup.lst
sleep 5
exit 0

See WinRAR command line switches explanation below.

Create a file opera-backup.lst in your home, add the following and make sure the paths are correct. If you don't want to backup a particular directory or file, add // before that line. Directories (skin, userjs) and files (download.dat, global.dat, vlink4.dat) are disabled by default.

// Opera backup using WinRAR command line
// Remove '//' before file path to archive that directory or file
//
// Directories to backup
.opera/dictionaries/ // Dictionaries
.opera/icons/ // Favicons
.opera/keyboard/ // Keyboard configuration
.opera/mail/ // Mail
.opera/menu/ // Menu configuration
.opera/mouse/ // Mouse configuration
.opera/plugins/ // Plug-ins
.opera/sessions/ // Sessions
.opera/styles/ // Styles
//.opera/thumbnails/ // Speed Dial thumbnails
.opera/toolbar/ // Toolbar configuration
//.opera/skin/ // Skin
.opera/toolbar/ // Toolbar configuration
//.opera/userjs/ // UserJS files
.opera/widgets/ // Widgets
// Files to backup
.opera/bookmarks.adr // Bookmarks
.opera/cookies4.dat // Cookies
.opera/contacts.adr // Contacts for e-mail & instant messaging
//.opera/download.dat // Download history
//.opera/global.dat // Global history
.opera/notes.adr // Notes
.opera/opcacrt6.dat // Certificate authorities
.opera/opcert6.dat // Personal certificates

.opera/typed_history.xml // Typed-in addresses
.opera/urlfilter.ini // Blocked content
//.opera/vlink4.dat // Visited links
.opera/wand.dat // Wand data
.opera/widgets.adr // Widgets configuration

Whenever you want to backup, type ./opera-backup.sh in terminal and WinRAR will create a backup file (example: opera-backup-061010-144215.rar) in your home.

If you want launcher, add /home/username/opera-backup.sh in command and enable Run in terminal



Windows



Use Opera backup list and WinRAR command line shortcut creator.




Create a backup shortcut in desktop with following parameters.
"C:\Program Files\WinRAR\WinRAR.exe" a -hppassword -m5 -r -agYYMMDD-HHMMSS D:\Backup\Opera- @Opera-Backup.lst
Right click on backup shortcut → Properties → Start in (delete the content usually it will have "C:\Program Files\WinRAR" → Shortcut key (press Ctrl+Alt+O).

C:\Program Files\WinRAR\ - Change this if path to your WinRAR directory is different.

a - Add files to archive.

-hppassword - If you want to password protect your backup keep it and replace password with your password else remove -hppassword. If you remove password, WinRAR will ask password during backup process. Without password it is impossible to view even the list of files in archive encrypted with -hp switch.

-m5 - Compression method.

-m0 do not compress file when adding to archive
-m1 use fastest method (less compressive)
-m2 use fast compression method
-m3 use normal (default) compression method
-m4 use good compression method (more compressive, but slower)
-m5 use best compression method (slightly more compressive, but slowest)

-r - Recurse subdirectories.

-agYYMMDD-HHMMSS - Generates archive name using the current date and time.

Y - year
M - month
MMM - month name as text string (Jan, Feb, etc.)
W - a week number (a week starts with Monday)
A - day of week number (Monday is 1, Sunday is 7)
D - day of month
E - day of year
H - hours
M - minutes (treated as minutes if encountered after hours)
S - seconds
N - archive number. RAR searches for already existing archive with generated name and if found, increments the archive number until generating a unique name.

D:\Backup\ - Change this path to your backup directory. This directory must exist.

Opera-Backup.lst - Create a file with this name and add the following lines and make sure the paths are correct. If you don't want to backup a particular directory or file, add // before that line. Directories (Skin, userjs) and files (global.dat, vlink4.dat and download.dat) are disabled by default. This file should be in same place where you created backup shortcut (in our case desktop).

// Opera backup using WinRAR command line
// Remove '//' before file path to archive that directory or file
//
// Directories to backup
C:\Program Files\Opera\program\plug-ins\ // Plug-ins
