In Bash, how do you append text immediately after a variable's value without creating a second variable?

• A. name=\"Bob\"; echo $nameby
• B. name=\"Bob\"; echo ${name}by
• C. name=\"Bob\"; echo ${name} by
• D. name=Bob; echo ${name}by

Answer: (B)

When you want to print or use text right after a variable’s value, delimit the variable with braces and append the literal text after the closing brace. This makes it clear where the variable ends and avoids Bash trying to treat the following characters as part of the variable name.

Example: name="Bob"; echo ${name}by

This prints Bobby. The braces ensure Bash uses the value of name and then attaches the literal by immediately after it. If you wrote $nameby, Bash would look for a variable literally named nameby (likely empty). If you wrote ${name} by, you’d get Bob and then a separate word by (because of the space). Using a quoted value name="Bob" is good practice to handle future cases with spaces, and ${name}by keeps the appended text tightly attached to the value.
