I know these have been asked before, but after searching for an hour or so, I was unable to find a complete answer.
Question 1. What is the full, proper, and space optimized syntax for 7-zip command line to recompress all jar files in a directory?
-still lost
-can't implement it yet
Question 2. What is the full, proper, and space optimized syntax for UPX?
-Answered, thanks Ryan
-currently being implemented
I'm asking these because I'm currently using my free time to write an AutoHotKey program, with GUI, that will allow the user to UPX all supported files in a given directory and subdirectories, as well as recompress all jar files in that directory and it's subdirectories.

For question 2, see the support page for almost any app.
e.g. AbiWord Support » Modifications
The options used were: --best --compress-icons=0 --nrv2d --crp-ms=999999 -k

thanks. I thought I had seen it somewhere, but then when I looked back, i just saw "compressed with UPX using optimized settings" or something like that

The UPX part is nearly finished, I have a question though. What is "--nrv2d --crp-ms=999999" I couldnt find these commands when I ran upx.exe --help. Were they commands in the older version that have now been replaced with something else, or did I just miss something?
I'd very much appreciate a response for the 7-zip commands as well. I found a post where John provided some syntax, but I can't get it to work properly, any help would be great. Thanks in advance.

The correct way to get extended help is "upx.exe -h", not "upx.exe --help".
If you read the docs on the UPX site they explain the compression engine options.
See v1.21 in the changelog too. http://upx.sourceforge.net/upx-news.txt
I'm advocating LZMA compression in the latest version of UPX so replace "--nrv2d" with "--lzma" for a tigher "squeeze" if you'd like.

Thanks, "upx --help" was the syntax listed in the readme, but in the actual displayed help after running that command says to use "upx -h". Thanks for the link as well. I now have UPX 3.0, and have noticed that lzma gets better compression by quite a bit
