Apropos ksh93 sleep and floating point parsing (and locales): % echo $SHELL /bin/tcsh % locale LANG=de_DE.ISO8859-1 LC_CTYPE=de_DE.ISO8859-1 LC_NUMERIC=de_DE.ISO8859-1 LC_TIME=de_DE.ISO8859-1 LC_COLLATE=de_DE.ISO8859-1 LC_MONETARY=de_DE.ISO8859-1 LC_MESSAGES=de_DE.ISO8859-1 LC_ALL= % time sleep 1.5 0.00u 0.00s 0:15.01 0.0% This surprises me a bit, it sleeps 10x longer than expected. % time sleep 1,5 0.00u 0.00s 0:01.51 0.0% Hmm, so sleep behaviour now depends on locale settings? How do we write portable shell scripts? % time env LC_NUMERIC=C sleep 1.5 0.00u 0.00s 0:15.01 0.0% I'd have assumed that the floating point parser obeys the LC_NUMERIC setting, but it seems to ignore it... % time env LC_ALL=C sleep 1.5 0.00u 0.00s 0:01.51 0.0% ... but LC_ALL works? Why not LC_NUMERIC? Btw. on Linux & gnu coreutils sleep the floating point parser seems to ignore the LC_* settings... In another environment with slightly different locale settings (LANG / LC_MESSAGES): > echo $SHELL /bin/tcsh > locale LANG= LC_CTYPE=de_DE.ISO8859-1 LC_NUMERIC=de_DE.ISO8859-1 LC_TIME=de_DE.ISO8859-1 LC_COLLATE=de_DE.ISO8859-1 LC_MONETARY=de_DE.ISO8859-1 LC_MESSAGES=de LC_ALL= > time sleep 1.5 0.00u 0.00s 0:15.02 0.0% > time sleep 1,5 0.00u 0.00s 0:01.52 0.0% > time env LC_NUMERIC=C sleep 1,5 Usage: sleep [ options ] seconds 0.00u 0.00s 0:00.01 0.0% We get a usage message when it can't parse the floating point value? > time env LC_NUMERIC=C sleep 1.5 0.00u 0.00s 0:01.52 0.0% % ksh93 j...@moritz:~$ locale LANG=de_DE.ISO8859-1 LC_CTYPE=de_DE.ISO8859-1 LC_NUMERIC=de_DE.ISO8859-1 LC_TIME=de_DE.ISO8859-1 LC_COLLATE=de_DE.ISO8859-1 LC_MONETARY=de_DE.ISO8859-1 LC_MESSAGES=de_DE.ISO8859-1 LC_ALL= j...@moritz:~$ time sleep 1.5 real 0m15,13s user 0m0,00s sys 0m0,00s j...@moritz:~$ time sleep 1,5 real 0m1,55s user 0m0,00s sys 0m0,00s j...@moritz:~$ time env LC_NUMERIC=C sleep 1.5 real 0m1,52s user 0m0,00s sys 0m0,00s j...@moritz:~$ time env LC_ALL=C sleep 1.5 real 0m1,58s user 0m0,00s sys 0m0,00s -- This message posted from opensolaris.org _______________________________________________ tools-discuss mailing list tools-discuss@opensolaris.org
