Tested on Ubuntu 16.04 to batch or bulk optimize all jpegs recursively given any folder using mozjpeg pre-compiled binaries. Execute the following commands:

First download and install mozjpeg... For 64bit: 

wget https://mozjpeg.codelove.de/bin/mozjpeg_3.2_amd64.deb
dpkg -i mozjpeg_3.2_amd64.deb

For 32bit: 

wget https://mozjpeg.codelove.de/bin/mozjpeg_3.2_i386.deb
dpkg -i mozjpeg_3.2_i386.deb

Then link mozjpeg's jpegtran...

ln -s /opt/mozjpeg/bin/jpegtran /usr/bin/jpegtran

Then download this perl script which will recursively scan for jpegs, optimize with the new jpegtran, and print results.

wget https://gist.githubusercontent.com/aksuited/96ea6144d9b62befbce23fd62b3b7b4d/raw/e31a74da9d7eaa6004969716f49c08e8d0a4de62/optimize_jpegs.pl

give the script permissions...

chmod 755 optimize_jpegs.pl

execute script...

optimize_jpegs.pl /path/to/jpegs

Sample Output:

# ./optimize_jpegs.pl /
