Thanks. I'm not that familiar with awk functions, simply because I came
of age after perl existed, and using perl tends to be more portable and
powerful (if you can assume it's available). But this is simple enough
that it should be OK.
Replacing it with:
"$TAR" tvf "$1" |
awk '{
split($4, date, "-")
print $3 " " date[1]
}'
seems to work.
