I'm wondering if Opera 15+ admits command line options like described here for 12 or earlier?
All I get when I run
-help are the feature switches, i.e., flags:
$ /Applications/Opera.app/Contents/MacOS/Opera -help Opera 23.0.1522.75 Stable Features available through command-line switches: --with-feature:accessible_panes : Enables keyboard navigation between various focusable panes (toolbar, tab bar, web content) by means of the shortcuts F6, Shift+F6, and F10. [Enabled by default: false] --with-feature:activation-order-tab-cycling : Enables tab cycling in activation order rather than tab strip order. [Enabled by default: false] --with-feature:warn-about-insecure-content : Enables a warning before insecure content is loaded over HTTPS. [Enabled by default: true] ......
There seem to be no ways to get behaviors like
activetab, etc. as seen in Opera 12 or earlier. One particularly annoying thing is that if there's no GUI window currently open, then I can't open a new window/tab from the command line:
$ /Applications/Opera.app/Contents/MacOS/Opera google.com [0813/175422:ERROR:process_singleton_posix.cc(264)] Failed to create /Users/zmwang/Library/Application Support/com.operasoftware.Opera/SingletonLock: File exists [0813/175422:ERROR:opera_browser_main_parts.cc(574)] Failed to create a ProcessSingleton for your profile directory. This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption.
Anyway to bypass this?
