HelenOS Command Reference

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).
