WHICH(1CSH)             COMMAND REFERENCE             WHICH(1CSH)



NAME
     which - report command interpretation (csh built-in)

SYNOPSIS
     which [ -a ] command...

DESCRIPTION
     The command which reports the interpretation of the given
     commands.  If the command is an alias, the text ``command is
     an alias for'' followed by the alias expansion, is printed.
     If the command is a built-in, the text ``command is a
     builtin command'' is printed.  Otherwise, the execution path
     is searched for command. If the command is in the path, the
     text ``command is pathname'' is printed.  If the command can
     not be found, the text ``command is not a command'' is
     printed.

OPTIONS
     -a Print all interpretations of the command instead of just
        the one that would be executed.

EXAMPLES
     Assume that the alias `echo' exists and is set to `cat \!*',
     and that the command /bin/echo exists, and that /bin is in
     the user's execution path.  Also, assume that there is no
     alias or command in the execution path called `goober'.  In
     this case, the command:

          which -a echo goober

     would print:

          echo is an alias for cat \!*
          echo is a builtin command
          echo is /bin/echo
          goober is not a command


RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [1]            An error of the type described in the message
                    occurred.

CAVEATS
     This command has a different use than pathof(1), and is not
     intended as a replacement.

     The execution path hashing is not taken into account during
     path searches, so it is possible for which to report a
     pathname which is not the same one used by csh(1csh).
