Linux: Jpeg Image Optimization / Compress Command

last updated in Categories , ,

I know how to optimize and compress png images using optipng command. line tool. I have lots of images in JPEG format. How do I compress and optimize JPEG images on my amazon cloud account so that I can save bandwidth on cloudfront cdn account? How do I use an image compressor to create lossless compression on JPEG files, with no effect on image quality in bulk using Linux?

I am using CentOS 5 on my laptop. If I open gnome-terminal by right clicking the desktop, I am getting an error that read as follows:

There was an error creating the child process for this terminal

How do I fix this problem and open a terminal by right clicking the Debian / Ubuntu / CentOS / Fedora / RHEL / Red hat Enterprise Linux 5.x desktop system?
