$ tldr --help
tldr - Simplified and community-driven man pages

Usage: tldr [-v|--version] ((-u|--update) | [-p|--platform PLATFORM]
            [-L|--language LOCALE] COMMAND | (-a|--about))
  tldr Client program

Available options:
  -h,--help                Show this help text
  -v,--version             Show version
  -u,--update              Update offline cache of tldr pages
  -p,--platform PLATFORM   Prioritize a specific platform while searching. Valid
                           values include linux, osx, windows, sunos
  -L,--language LOCALE     Preferred language for the page returned
  COMMAND                  name of the command
  -a,--about               About this program
  --auto-update-interval DAYS
                           Perform an automatic update if the cache is older
                           than DAYS

Or a much better example of the usage:

$ tldr tldr
Simplified man pages. More information:

 - Get typical usages of a command (hint: this is how you got here!):
   tldr {{command}}

 - Show the tar tldr page for linux:
   tldr -p {{linux}} {{tar}}

 - Get help for a git subcommand:
   tldr {{git checkout}}

Offline caching

On the first run, this program caches all available tldr pages. Since the number of available tldr pages rises quickly, it is recommended to regularly update the cache. Such an update can be run manually with:

$ tldr --update

Starting with version 0.9.0, users of this client can enable automatic updates by running it with the option --auto-update-interval DAYS specified. The client will then check whether the cached version of the tldr pages is older than DAYS days and perform an update in that case. To enable this functionality permanently, users can put the line alias tldr="tldr --auto-update-interval DAYS" in their shell configuration file (e.g. .bashrc, .zshrc) with the desired update interval specified.
