'==' is bashism, '=' needs to be used for comparison.
With this fix script can work on systems where the default shell is
dash, busybox ash or any other strictly POSIX compatible shell.
While at it, also improve:
* remove "x" in the comparison (not needed for decades)
* use $# for checking number of arguments
* cleanup whitespace
