PR Summary

• 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.
