Pattern: Use of read without -r
Issue: -
By default, read will interpret backslashes before spaces and line feeds, and otherwise strip them. This is rarely expected or desired.
Normally you just want to read data, which is what read -r does. You should always use -r unless you have a good reason not to.
Note that read -r will still strip leading and trailing spaces. IFS="" read -r prevents this.
Example of incorrect code:
echo "Enter name:"
read nameExample of correct code:
echo "Enter name:"
read -r name
