[GRASS-dev] Return value from g.copy is one when --overwrite - bug or feature?

[Rainer M Krug]

When copying via g.copy and specifying --overwrite and the target object
already exists, the return value is 1 but no error message is returned:

,----
| simASM:grassAnalysis> g.copy --overwrite region=region1,region2
| simASM:grassAnalysis> echo $?
| 1
| simASM:grassAnalysis>  g.version
| GRASS 7.0.1 (2015)
| simASM:grassAnalysis>
`----

From http://tldp.org/LDP/abs/html/exit-status.html:

,----
| A successful command returns a 0, while an unsuccessful one returns a
| non-zero value that usually can be interpreted as an error code.
`----

So shouldn't the return value be 0 in this case, as the command did what
it was told?

Cheers,

Rainer
