Opera FAQs, Tips, Tricks & Tweaks

Last year, I posted Opera Bookmarks Description Remover for Windows to reduce bookmarks file size by removing bookmarks description. You can do it in Linux using shell script or Terminal command.

Shell script

1. Create a file with name opera-bookmarks-description-remover.sh with the following code inside ~/.opera directory.

   #! /bin/bash
   #
   # A script to remove Opera bookmarks description
   #
   # Place inside ~/.opera and make it executable (chmod a+x)
   #
   
   mv bookmarks.adr bookmarks.adr.bak
   awk '!/DESCRIPTION=/' bookmarks.adr.bak > bookmarks.adr

   
   opera-bookmarks-description-remover.sh file inside ~/.opera directory

2. Right click on opera-bookmarks-description-remover.sh > Properties > Permissions > [Enable] Allow executing file as program

   
   Enable 'Allow executing file as program'

3. Close Opera.
4. Open opera-bookmarks-description-remover.sh > Run

   
   Click 'Run in Terminal' or 'Run' button

Terminal command

Close Opera and run the following code in Terminal.

cd ~/.opera && mv bookmarks.adr bookmarks.adr.bak && awk '!/DESCRIPTION=/' bookmarks.adr.bak > bookmarks.adr

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/operaprefs.ini // Opera settings .opera/opssl6.dat // SSL preferences .opera/override.ini // Site preferences .opera/search.ini // Search engines .opera/speeddial.ini // Speed Dials .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 C:\Program Files\Opera\profile\dictionaries\ // Dictionaries C:\Program Files\Opera\profile\icons\ // Favicons C:\Program Files\Opera\profile\keyboard\ // Keyboard configuration C:\Program Files\Opera\profile\mail\ // Mail C:\Program Files\Opera\profile\menu\ // Menu configuration C:\Program Files\Opera\profile\mouse\ // Mouse configuration C:\Program Files\Opera\profile\sessions\ // Sessions // C:\Program Files\Opera\profile\skin\// Skin C:\Program Files\Opera\profile\styles\ // Styles // C:\Program Files\Opera\profile\thumbnails\ // Speed Dial thumbnails C:\Program Files\Opera\profile\toolbar\ // Toolbar configuration // C:\Program Files\Opera\profile\userjs\ // User JavaScript files C:\Program Files\Opera\profile\widgets\ // Widgets // Files to backup C:\Program Files\Opera\profile\bookmarks.adr // Bookmarks C:\Program Files\Opera\profile\cookies4.dat // Cookies C:\Program Files\Opera\profile\contacts.adr // Contacts for e-mail & instant messaging //C:\Program Files\Opera\profile\download.dat // Download history //C:\Program Files\Opera\profile\global.dat // Global history C:\Program Files\Opera\profile\notes.adr // Notes C:\Program Files\Opera\profile\opcacrt6.dat // Certificate authorities C:\Program Files\Opera\profile\opcert6.dat // Personal certificates C:\Program Files\Opera\profile\operaprefs.ini // Opera settings C:\Program Files\Opera\profile\opssl6.dat // SSL preferences C:\Program Files\Opera\profile\override.ini // Site preferences C:\Program Files\Opera\profile\search.ini // Search engines C:\Program Files\Opera\profile\speeddial.ini // Speed Dials C:\Program Files\Opera\profile\typed_history.xml // Typed-in addresses C:\Program Files\Opera\profile\urlfilter.ini // Blocked content //C:\Program Files\Opera\profile\vlink4.dat // Visited links C:\Program Files\Opera\profile\widgets.dat // Widgets configuration C:\Program Files\Opera\profile\wand.dat // Wand data

Whenever you want to backup, press shortcut key, Ctrl+Alt+O and WinRAR will create a backup file (example: Opera-050319-153045.rar) in D:\Backup\ directory. See user's manual, Rar.txt in WinRAR directory to learn more about console RAR. Update Oct 17, 2006: Linux version Nov 12, 2009
