java - gzip a folder and its subfolders on the fly -

-

i have big folder want send zipped version of while saving on sub-folders hierarchy.

currently i'm doing creating large zip file , sending it.

i'm looking way write folder content outputstream redirected socket output stream.

my motivation avoid keeping large files in machine on run time

i know how single file, have no idea how process folder many sub folders , save inner hierarchy...

thanks!

it's little unclear you're after, since gzip has no notion of files - bytes compressed - need archive format tar combine bunch of files , directories single stream, , can gzip that.

if want compressed archive format, jdk's zipoutputstream let use zip compression.

if need gzip format, there number of implementstions of tar output streams out there - use 1 of , pipeline jdk's gzip output stream.

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.
