NAME

       which - locate a command

SYNOPSIS

       which [-a] filename ...

DESCRIPTION

       which returns the pathnames of the files (or links) which would be executed in the current
       environment, had its arguments been given  as  commands  in  a  strictly  POSIX-conformant
       shell.   It does this by searching the PATH for executable files matching the names of the
       arguments.  It does not canonicalize path names.

OPTIONS

       -a     print all matching pathnames of each argument

EXIT STATUS

       0      if all specified commands are found and executable

       1      if one or more specified commands is nonexistent or not executable

       2      if an invalid option is specified
