I want to
mv files and not overwrite duplicates. The
-b switch only makes a single backup file, whereas I may have many.
According to the
mv man page:
The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the --backup option or through the VERSION_CONTROL environment variable. Here are the values:
never make backups (even if --backup is given)
make numbered backups
numbered if numbered backups exist, simple otherwise
always make simple backups
I think I want to use the 'existing, nil' option... but I can't figure out how to call that.
If my command is:
mv $src $dest
How can I implement the 'existing, nil' option?
