Спасибо, я как-то об этом не подумал. По мотивам получилось так:
#!/bin/bash
jTODAY=`date +%j`
YEAR=`date +%Y`
DAY=`date -d 20110101 +%Y-%m-%d`
jDAY=`date -d 20110101 +%j`
until [ "$jDAY" -gt "$jTODAY" ]
do
file="$YEAR"/"$jDAY".dat
[ ! -f $file ] && echo "File $file is absent"
DAY=`date -d "$DAY + 1 day" +%Y-%m-%d`
jDAY=`date -d $DAY +%j`
done
Вероятно можно ещё красивше сделать...
