The reason why these mustn't be identical (apart from different behaviour for --help and --version) should be clear from the following example: if test -z $MYVAR; then .. fi vs. if [ -z $MYVAR; then .. fi The first is valid, the second is not and *must* fail. HTH, Stefan. You’ll find the answer in coreutils test.c, which gets compiled twice.

The reason why these mustn’t be identical (apart from different behaviour for –help and –version) should be clear from the following example:

if test -z $MYVAR; then
..
fi

vs.

if [ -z $MYVAR; then
..
fi

The first is valid, the second is not and *must* fail.

HTH,
Stefan.
