This would be append: 3: export TMPDIR=/var/tmp:$TMPDIR This is how I understand it; if a matching path is found, it is considered for the task at hand. So prepend (front) would mean "I want this to be considered before everything else", whereas append (back) would mean "I want this to be considered when everything else fails". The easiest example to see it in action is the PATH variable. Does that make sense? -- Suvayu Open source is the future.
