To get the value of environment variable called PATH, use the following expression:

'${PATH}'

	Important
	Use single quotes when referring to path environment variables, especially on Windows. This is necessary to avoid conflicts between double quotes delimiting the string value of the variable, and possible double quotes contained within the value itself.

To get the value of a variable whose name contains dots (e.g, java.io.tmpdir), replace each dot with underscore character and type:

'${java_io_tmpdir} '

Note that the terminal single quote must be preceded by a white space since java.io.tmpdir itself ends with a backslash and we do not want to get an escape sequence (\'). With this white space we will get \ ' at the end.

	Important
	Use single quotes to avoid escape sequences in Windows paths.
