Which command can be used to check the current value of the PATH environment variable?

The command that can be used to check the current value of the PATH environment variable is the one that utilizes the echo command followed by the variable prefixed with a dollar sign. In this case, echo $PATH effectively outputs the value of the PATH variable to the terminal. The PATH variable is a crucial environment variable in Unix-like systems that specifies a colon-separated list of directories where executable files are located. By using echo $PATH, the user can quickly see which directories are included in their current PATH, enabling them to understand where the system looks for executable commands.

The other choices do not utilize the correct syntax or commands commonly used in a shell environment. For instance, both "print PATH" and "show PATH" do not follow the standard command conventions in Unix-like systems, while "display $PATH" is also not a recognized command for accessing environment variable values.
