catch an scp error?

When scp tries to overwrite an existing file (without group write) I get permission denied, otherwise it sends it or rewrites it.


$ scp Test.zip linus@penisland.net:/path/to/dicks/Test.zip
linus@penisland.net's password:
scp: /path/to/dicks/Test.zip: Permission denied

How do I catch that permission denied error (no group write) so my script can try sending it again with a different name?

Would it be easier to detect the permissions ahead of time and sudo chmod accordingly?

The scp'd file's permissions are preserved. When I $touch the permissions are -rw-rw-r--.

thanks

Well done, you can identify /prog/ in-jokes. Next lesson in becoming a true /prog/dolyte: using sage
