NAME
  which - Locates a program file including aliases and paths

SYNOPSIS
  which program...

DESCRIPTION
  The which command takes a list of program names and looks for the files
  that would be executed if these names were given as commands.

  Each program argument is expanded if it is aliased and searched for along
  your path.  Both the aliases and path are taken from your .cshrc file.  If
  you do not have a .cshrc file, the path is the current PATH from your
  environment.

  The which command is written in csh script language and only works in the C
  shell. The ksh program offers the built-in commands type and whence that
  perform the same function as which.  The sh built-in command type can also
  be used.

FILES
  $HOME/.cshrc
      Read at beginning of execution by each shell.

DIAGNOSTICS
  A diagnostic is given if an executable file with the argument name was not
  found in the path.
