Once upon a time there were Bell Labs...

Today is another step closer to the end of an era for the old AT&T Bell Labs (now called AT&T Labs). Our valued colleague David Korn (inventor of the famous Korn Shell - ksh) is leaving the labs, and he sent us the following farewell message in a form of (what else?) a Korn Shell script:

cd /tmp
if [[ $(print hello) != hello ]] 2> /dev/null
then echo 'You should use ksh'
 alias print=echo
trap 'rm mvs2*' EXIT
trap 'print "$year: dgk raptured to dgk@xxxxxxxxx"' TERM
for x in 76 78 80 81 83 86 87 88 89 90 91 93 95 99 100 103 107 108 110 112 113
do case $((year=1900+x)) in
 1976) print "$year: Hello Bell Telephone Labs, Holmdel; Goodbye NYU";;
