During script execution, an administrator needs to ensure a command is executed only when a certain variable holds the exact word 'config'. Which syntax will correctly verify this within an if statement?
[[ $VARNAME -eq 'config' ]]
[[ $VARNAME == 'config' ]]
[[ $VARNAME != 'config' ]]
[ $VARNAME == 'config' ]
The conditional test using == is the correct answer because in shell scripting, this operator is used to compare two strings for equality. The single [ and double [[ are both used for the test construct, but the double bracket [[ is a newer Bash construct that offers additional functionality, such as regex matching and doesn't require quotes around the variable. The other answers are incorrect because -eq is used for arithmetic comparison, and using != would check for inequality, which is not the desired operation.
