"updatedb; locate foo" vs "ls -laR > somefile; grep foo somefile" -

-

on single-user system security isn't issue, there any
advantage using "updatedb" , "locate" (or slocate or mlocate) instead of doing "ls -lar > somefile" nightly , using "grep phrase somefile" find files?

in fact, seem grep more flexible locate since allows regular expressions.

what missing here?

for specific scenario, differences marginal, locate database optimized fast searches.

on multiuser system, modern locate replacements have various additional security features e.g. not reveal user files have in private directories.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
