Hi Stewart, you could just |watch| the file listing (adjusting n seconds to whatever is suitable)

I hadn't heard of watch before, so thanks! watch *started* to work really well, but then went into a terminal sulk after the FS disappeared during a scan, and refused to show any updates. It's also an interactive program, so doesn't pipe or notify changes in any useful way.
I suspect I'll just have to go with William Park's suggestion of using rsync to a local folder that I have more control over. I still have to correct for the scanner FS's wandering clock, but that's less important.
Here's a quick and dirty bash script similar to the watch command; adjust to taste. :-) [- watchdir.sh snippet starts -] #!/usr/bin/env bash # # USAGE # watchdir.sh <rate> <path> # # Determine our sampling rate WATCHRATE=${1} if [[ "" = "${WATCHRATE}" ]]; then WATCHRATE=10 fi # Determine our watch directory WATCHDIR=${2} if [[ "" = "${WATCHDIR}" ]]; then WATCHDIR="." fi # Describe what we're doing echo "Watching ${WATCHDIR} every ${WATCHRATE}s:" # Render a side-by-side comparison with last snapshot of our directory # note: assumes at least one snapshot already exists function sample_watchdir { cp .current .previous date > .current ls -l ${WATCHDIR} >> .current echo "" diff -y .current .previous } # Begin watching date > .current ls -l ${WATCHDIR} >> .current sample_watchdir # Every WATCHRATE seconds, make the current file listing our previous # listing, take a fresh look at WATCHDIR and compare the changes while sleep ${WATCHRATE}; do sample_watchdir done [- watchdir.sh snippet ends -] -- Scott Elcomb @psema4 http://www.pirateparty.ca/
