The thing is - I don't want to go to some website or pour through pages and pages of documentation when I want to do one specific thing. I want to do something and move on with my life. My job isn't learning every command line switch under the job.
man man | grep -A 10 EXAMPLES
man tar | awk -F , '/-v,/ {print $2}'
I'm happy TLDR fits your needs. I was just demonstrating how I use manpages effectively in hopes it might assist you.
