Question

Each blank line below indicates a token. How does the bash shell interpret each token in proper Linux syntax? Use U for utility, F for file and A for argument:

 

The image appears to contain code-like expressions with blanks to be filled in, formatted as follows: A. `$______ ______ < ______ || ______ > ______ ; ______ | ______` B. `$______ | ______ && ______ ; ______ ' ______ | ______ ' || ______` C. `$______ ______ | ______ ; ______ ______ ' ______ ______ '` D. `$______ ______ | ______ $______ > ______ ; ______ ______ > ______` These expressions seem to represent conditional statements in a programming language, and the blanks are likely placeholders for variables, values, or operators to be filled in. Here is a brief explanation of the components: 1. **Operators:** - `<`, `>`, `&&`, `||`: Common logical and comparison operators used in programming. - `<` or `>`: Less than or greater than. - `&&`: Logical AND. - `||`: Logical OR. - `|`: Bitwise OR, also sometimes used for other operations in certain contexts. 2. **Symbols:** - `$`: Often denotes a variable or signifies the start of a variable name in many programming languages (e.g., PHP, shell scripting). - `'`: Typically used to denote strings or characters. 3. **Structure:** - Each line represents a logical expression or statement that might be part of a larger script or function in a programming or scripting language. - The use of `$`, `&&`, `||`, and other symbols indicates these are likely part of a conditional or logical check. These expressions are likely aimed at teaching logical constructs, conditional operations, or syntax in programming exercises.
