Debugging ksh scripts

[franl at damogran.prime.com]

Look for something like this:

  if [ $VAR ]
  then
    ...
  fi

which is testing (poorly) whether the value of the variable VAR is not
the null string.  When VAR is not set, it is interpreted as

  if [ ]		<=== here, "[" (aka "test") has no arguments!
  then
    ...
  fi
