Jonathan, Okay, here ya go: # mount -o remount,ro /d2 # env -i strace -o /tmp/dash-test-w-directory.strace -f -s 128 /bin/dash -c '[ ! -w /d2 ] && echo "Not Writeable"' # env -i strace -o /tmp/dash-test-w-file.strace -f -s 128 /bin/dash -c '[ ! -w /d2/foompy ] && echo "Not Writeable"' Not Writeable # env -i ltrace -o /tmp/dash-test-w-directory.ltrace -f -s 128 /bin/dash -c '[ ! -w /d2 ] && echo "Not Writeable"' # env -i ltrace -o /tmp/dash-test-w-file.ltrace -f -s 128 /bin/dash -c '[ ! -w /d2/foompy ] && echo "Not Writeable"' Not Writeable Let me know if you need the output from doing this with 'bash' for comparison. (I'm not doing it until you ask, 'cause i'm lazy, too ;) ) thanks, --stephen -- Stephen Dowdy - Systems Administrator - NCAR/RAL 303.497.2869 - sdo...@ucar.edu - http://www.ral.ucar.edu/~sdowdy/
