You could consider using an alias, e.g.:
alias ddusb "dd bs=4096 conv=fsync"
You could add this to your shell startup files, e.g., the ~/.bashrc file.
Some GNU/Linux distributions read the file ~/.bash_aliases if it exists,
with the intent to place alias definitions there.
This is a good suggestion. I would like to add, however, that an alias
(or function) in $BASH_ENV instead of ~/.bashrc has an added benefit
of being available for other programs when the shell is not interactive
(as with vim's command line, for example).
