How do I "read" a variable on a while loop

bash, variables, while-loop

Solution

You can write:

while IFS= read -r line
do
    echo "$line"
done <<< "$the_list"

See §3.6.7 "Here Strings" in the Bash Reference Manual.

(I've also taken the liberty of adding some double-quotes, and adding `-r` and `IFS=` to `read`, to avoid too much mucking around with the contents of your variables.)

Problem

How can I read from variable with `while read line`? For example: ``` the_list=$(..code..) while read line do echo $line done < $the_list ``` using the code above gives me error: ``` ./copy.sh: line 25: $the_list: ambiguous redirect ```
