Your colleague told you nonsense!
Code:
du -sk *

does the same as
Code:
du -sk ./*

but reports the plain file names instead of prefixing them with ./.
And tell him you are running du -sk ././* for double safetySmilie

Some variation using awk
Code:
du -sk * | sort -rn | awk '{if ($1>1048576) {$1=$1/1048576;t="GB"} else if ($1>1024) {$1=$1/1024;t="MB"} else {t="KB"}} NR < 11 {printf "% 10s %s %s\n",$1,t,$2}'

Code:
du -sk * | sort -rn | awk '{
	if ($1>1048576) {$1=$1/1048576;t="GB"} 
	else if ($1>1024) {$1=$1/1024;t="MB"} 
	else {t="KB"}
	} 
	NR < 11 {printf "% 10s %s %s\n",$1,t,$2}'

With two efficiency tricks and extended range it becomes
Code:
du -sk * | sort -rnk1 | awk '
NR>10 {exit}
{
  if ($1>1073741824) {$1=$1/1073741824; t="TB"}
  else if ($1>1048576) {$1=$1/1048576; t="GB"}
  else if ($1>1024) {$1=$1/1024; t="MB"}
  else {t="KB"}
}
{printf "%10s %s %s\n",$1,t,$2}
