I don’t understand why people think this is such a useful thing. Sure it has some good summaries but you can’t find all info there whereas man pages should have everything. It’s also good that tldr has examples but I think it’s something man should more often have too. So why would people rather use this than man?
For example I often forget the order of pattern and file in grep. I can look it up easily in both man and tldr. I also forget what was the short option for recursion. Was it -r, -R or either or something else entirely? I can easily do a search on my pager to find the option in man but there’s only long option available in tldr. That’s Too Long Don’t Want to Type.
Would you agree that man page with good example section of common use cases would better serve the purpose or do you think there has to be separate tool to show only a short summary of the manual?
