Enhanced Bash Conditional Expressions
The update clarifies that the -v operator in Bash conditional expressions operates using the variable name directly, not the variable's value. This clears up any ambiguity for developers and improves the comprehensibility of the code.
Added Instructional Note
A newly added note provides guidance that using ${varname} in these instances would yield false as opposed to carrying out the required evaluation. This guidance prevents potential code errors and fosters better coding practices.
