- shells interpret '*' and other globs:
    * If programs does not interprets theses globs themselves, they cannot
      do additional checks, e.g. `rm` cannot check `*` to avoid potential
      dangerous actions.
    * If programs interprets these globs themselves, like `git` or `hg`,
      then shells' interpretation is redundant.

- Special characters like spaces, tabs, new lines are valid in file names,
  but shells are unhappy with them.

- Different UNIX ship different commands. Nowadays things are much better,
  but this problem still exist, mostly between bsd(darwin) and linux.

- Data passes through programs as strings. Sender need to encode and
  receiver need to decode. What makes things worse is there are no
  common standard strings format for interoperation.
