NAME
       which - locate a command and display its pathname or alias

SYNOPSIS
       which [name]...

DESCRIPTION
       which takes a list of names and determines which alias or utility would
       be executed had these names been given as commands.

       For each name operand, if it names an  alias  the  alias	 is  expanded.
       Otherwise the user's path is searched for a utility name matching name.
       Aliases are taken from the user's .cshrc file. path is taken  from  the
       current shell   execution environment.

OPERANDS
       The following operand is supported:

       name
	       The name of a command to be located.

EXIT STATUS
       The following exit values are returned:

       0
	      Successful completion.

       >0
	      One or more name operands were not located or an error occurred.

FILES
       ~/.cshrc
		   source of aliases and path values

SEE ALSO
       csh(1), attributes(5)

DIAGNOSTICS
       A diagnostic is given for names which are aliased to more than a single
       word, or if an executable file with the argument name was not found  in
       the path.

NOTES
       The which utility is not a shell built-in command.

BUGS
       To  compensate  for  ~/.cshrc  files  in	 which aliases depend upon the
       prompt variable being set, which sets this variable to  NULL.   If  the
       ~/.cshrc produces output or prompts for input when prompt is set, which
       can produce some strange results.
