 ====== BASH - Files - Read a file - Input source selection ======
+Usually read has a filename as its input.
+To instead use the contents of a variable/parameter as the file to read:
+<code bash>
+while IFS= read -r line; do
+  printf '%s\n' "$line"
+done <<< "$var"
+</code>
+----
+The same can be done in any Bourne-type shell by using a "here document" (although read -r is POSIX, not Bourne):
+<code bash>
+while IFS= read -r line; do
+  printf '%s\n' "$line"
+done <<EOF
+$var
+EOF
+</code>
