I tried on Ubuntu 11.10 and got same error. Its working for me on Ubuntu 10.04 though the awk version seems same on 10.04 and 11.10

Below command should work for you.

ps -eo size,pid,user,command | sort -rn | head -5 | awk '{ hr[1024^2]="GB"; hr[1024]="MB"; for (x=1024^3; x>=1024; x/=1024) { if ($1>=x) { printf ("%-6.2f %s ", $1/x, hr[x]); break } } } { printf ("%-6s %-10s ", $2, $3) } { for ( x=4 ; x<=NF ; x++ ) { printf ("%s ",$x) } print ("\n") }'
