Lua: specify file name with variables

I'd like to specify a filename based on a different id number. How can I set different a file name according to a different id value?

id = args.bdp_id
filename = "./temp/vtx_vel%d.dat", id
print (filename)

See string.format if you want to use sprintf style substitutions: 

filename = string.format("./temp/vtx_vel%d.dat", id)
