Counting
In the beginning I used TOTAL=`ls /d2lmig/*/*/bak/*/* | wc -l` to get a total count. All was good. Until at around 55,000 files I got: -bash: /bin/ls: Argument list too long.

Bb 9 is NextGen?
UPDATE: Have another source who disagrees with Badge who made the claim below. ——— Hopefully this is true. I’d hate to be spreading a false rumor. Anyone willing to confirm? 😀 According to J. L. Badge, Blackboard 9 will be the “NextGen” product we are… *cough* eagerly… *ahem* waiting to see. John Fontaine was in…
