Hello,
Seems in going to sh-utils 2.0 the default behavior of "who" when invoked
as "who am i" has changed and this breaks many people's scripts.
In particular, a common way in ~/.profile & ~/.cshrc to set the DISPLAY
for remote logins is to run "who am i" and extract the (hostname)
or (:0.0) that comes from the last field. who in sh-utils 2.0 no
longer does this (see below). It appears the "-l" or "--lookup" option
does provide this info, so that could be used as a workaround, however
for an inhomogenous environment where a user's ~/.profile is shared
for many flavors of Unix this doesn't work either.
Is it that important to have "-l" be completely orthogonal from
everything else so as to break many people's scripts using "who am i"?
Were it up to me, "who am i" for GNU who would imply -l. Even
a WHO_OPTS environment variable would be nice...
Thanks,
Karl Runge
