Is there an easy way to allow multiple dirs in SH_CMDLIB_DIR ? In
Solaris /bin is a soft link to /usr/bin - but the builtin commands in
Solaris ksh93 only appear in /bin:
-- snip --
% builtin | /usr/bin/fgrep "/"
/bin/basename
/bin/cat
/bin/chmod
/bin/cmp
/bin/cut
/bin/dirname
/bin/head
/bin/logname
/bin/mkdir
/bin/uname
/bin/wc
-- snip --
... but Solaris scripts madly reference them with both
"/usr/bin/name_of_program" and "/bin/name_of_program" (or use something
like "PATH=/usr/bin:/bin" etc.), sometimes even within the same
script... ;-(
IMO both "/usr/bin/name_of_program" and "/bin/name_of_program" should be
listed by % builtin | /usr/bin/fgrep "/" # if /bin/ is a link to
/usr/bin/ ... or not ?

Comments/ideas/suggestions welcome...

Bye,
Roland
