Which command checks if "$a" ends with the string "find me"?

• A. $a -eq "find me"
• B. $a -contains "find me"
• C. $a -like "*find me"
• D. $a -match "find me$"

Answer: (C)

The command that checks if the variable "$a" ends with the string "find me" is indeed utilizing the pattern-matching capabilities of the language, which is represented by the command using the wildcard syntax. The wildcard character "*" is employed here to match any sequence of characters that may precede "find me" at the end of the string stored in "$a". In this context, the asterisk "*" signifies that there can be any characters of any length before "find me". Hence, the command effectively checks for the presence of "find me" specifically at the end of the string contained in "$a". This is a standard way of performing such checks in pattern matching scenarios, allowing for flexible string evaluations. The other options do not accomplish the task of verifying if "$a" ends with "find me". For instance, using equality checks or the "contains" command does not support substring position checking as required in this situation. The "match" command, while it could potentially work with regular expressions, does not specify that "find me" must be at the end of the string without additional syntax indicating that constraint. Therefore, the wildcard syntax in the choice provided is the most accurate method to check the specified condition.
