Linux "top -c" to show full command

top per se doesn't support wrapping, if i am correct. One way is you can increase your terminal width as follows.

export COLUMNS=_NO_YOU_DESIRE_
top

** then set update interval with 's _REFRESH_INTERVAL_'
** turn on command line display with 'c'

htop shows the full command. You can scroll to the right to see it all.

You can also rearrange, add and remove the columns to just show the information you are interested in. Press h inside top for details (or man htop in the terminal).
