WHICH(1)                    General Commands Manual                   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 exe-
       cuted 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

SEE ALSO
       csh(1)

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.

BUGS
       Only aliases and paths from ~/.cshrc are used; importing from the  cur-
       rent  environment  is not attempted.  Must be executed 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.  If the ~/.cshrc
       produces output or prompts for input when prompt is set, which may pro-
       duce some strange results.
