== Description of categories ==

|| '''Category''' || ''Description'' ||
|| bdsh           || Shell built-in commands. Type `help commands` in the shell for a listing. ||
|| app            || Application category. Command-line driven or interactive commands. `ls /app` for a listing ||
|| srv            || Services category. They work in background and not all should be started by hand. `ls /srv` for a listing ||

== Default executable directories ==

If you type in a command in Bdsh without path will try to find a shell built-in, then it will look into `/app` and `/srv`. There are other executables in a HelenOS system, namely the DDF-based drivers under `/drv`. This directory is not searched as DDF drivers are started automatically by Devman and you never need to run them by hand (although it is possible).
