Hello. My name is Alister and I have a sickness. Sometimes I can't help but revisit inconsequential, properly functioning commands to make them a tiny bit shorter.
Code:
awk '{while ($1>=t*w) t++; A[t]++} END {for (i=1;i<=t;i++) print i*w"\t"(A[i]+0)}' w=10000 data
As a bonus, the interval's width can be easily modified on the command line.
