User Commands                                            which(1)

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.
