How to get all tables of hbase in linux shell script and operate on each table？
Now I can do it with this code, but is there a better way to do this?
output=`echo "list" | hbase shell`
output=`echo ${output} | cut -d'[' -f 2 | cut -d']' -f 1`
IFS=',' read -ra tables <<< "$output"
for tb in "${tables[@]}"; do
echo "${tb}n"
done
I thought it is not that graceful to parse the output and wonder if there is a better way to do this.

You could simplify that a bit more as shown here. This involves no intermediate variable declaration, hope it helps you.
echo 'list' | hbase shell | sed -e '1,/TABLE/d' -e '/seconds/,$d' |
while IFS='' read -r line || [[ -n "$line" ]]; do
echo "$line"
done
