Diff btw EXPORT, ENV and SET

[lokem]

Hi all,

Anyone knows the difference btw the EXPORT, ENV and SET commands?

TIA.

Now I'm just being picky - they're not commands . Commands are written in lower case. The differences vary a bit, it depends on the shell. export doesn't display anything if you don't put any parameters but env shows the current environment.
In sh shell, export and set are the same command.
