Better. A few minor nits:
The new subroutine is only parsing/invoking a single command at a time
from the input line rather than multiple commands, so the name
parse_commands() is slightly misleading. Perhaps parse_command() would
be more appropriate.
Now that the functionality has been pushed into a subroutine, it does
not necessarily need to be accessing global @cmd. It might be
appropriate to pass @cmd as an argument to parse_command() (or not
depending upon your preference).
The "Unknown command. Aborting" case indicates a failure. It's pretty
typical for failures to return false rather than true. The resulting
conditional would then read a bit more idiomatically:
if (!parse_command(\@cmd)) {
last;
