I have installed my flash application using packagemaker installer. I have created short cut to desktop using shell Script. Now i want to change the default short cut Icon. Please tell me shell script to change the short cut icon.
MAC OS 10.7.2
Mac OS X doesn't have "shortcut files". It has either alias files or symbolic links (symlinks).
I imagine that you created a symlink, since you're working from a shell. Symlinks can't have custom icons. They have almost no real data or metadata of their own.
I don't know of a way to set an icon for an alias file (or any other file) from the shell. My first thought was AppleScript, which you can use from a shell via the osascript command. But I find that the Finder's AppleScript support does not include working with file icons. There's a definition of an icon family class, but it's marked as "NOT AVAILABLE YET".
