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


SYNOPSIS
      which [ filename ... ]
 


DESCRIPTION
      which takes a list of names and looks for  the  files  which
      would  be  executed  had these names been given as commands.
      Each argument is expanded if it is aliased, and searched for
      along  the user's path. Both aliases and path are taken from
      the user's .cshrc file.
 


FILES
      ~/.cshrc
            source of aliases and path values
 
      /usr/bin/which

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


NOTES
      which is not a shell built-in command; it is the  UNIX  com-
      mand, /usr/bin/which
 
 BUGS
      Only aliases and paths from  ~/.cshrc  are  used;  importing
      from  the current environment is not attempted. Must be exe-
      cuted by csh(1), since only csh knows about aliases.
 
      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 may produce some strange
      results.
