wshhelp file:

(also take a look at 'help starting')

wsh gives you a unix like shell using mud securities.  You have access to
the following commands:

  all the programs in /bin
  cd:  changes directory.  With no argument will default to $HOME
  source and .:  sources a wsh file
  wsh:  spawn wsh again
  wsh -l:  login again
  acc:  show access tree (read and write)
  history:  print history (or set size with number argument)
  !<num>:  do <num> command from history
  !<str>:  do command that matches string in history
  set (or setenv):  show current environment
  set <var> <value>:  set variable (also setenv) (no unset implemented!)
  alias:  print aliases
  alias <name>: show alias <name>
  alias <name> <what>: alias <name> to <what>
  unalias <name>:  remove alias to <name>  ('unalias' cannot be aliased)
  help:  show this file
  help topics:  show help topics
  help starting:  some starting help info
  help wsh.man:  see the wsh man page
  exit and logout: quit wsh
  who:  shows a list of who's on
  chat <string>:  say something to everyone on
  tell <who> <string>:  tell something to someone specific
       !! Don't forget that the exclamation mark will be expanded
       !! as a history command if it is followed by: a number,
       !! a substring of characters, or another exclamation mark
  mesg [y|n]:  Lets you turn messages (chat and tell) on and off
  version:  Gives you the current version of wsh
  
  When started, wsh will source /.wshrc.global and $HOME/.wshrc
  If it is a login, it will also source /.login.global and $HOME/.login
  Shell escapes and environment variable and history expansion work.
  Wildcard expansion does not work yet.  (filenames with *)
  You can 'set prompt "<string>"', and %/ will be expanded to current path.
