How to specify a multi-line shell variable?
bash, shell
Solution
Use `read` with a heredoc as shown below:
read -d '' sql << EOF
select c1, c2 from foo
where c1='something'
EOF
echo "$sql"
Problem
I have written a query: ``` function print_ui_hosts { local sql = "select ........." print_sql "$ sql" } ``` local sql - a very long string. Query is not formatted. How can I split a string into multiple lines?
