how to crack multiple hashtype in the same time

I see some can crack mutilple hashtype on hashcat by the same,can any one tell me how to do it?
I have see hashcat help,the parameter -m can only input one number,why can some crack mutilple hashtype?
There cracked output like these:
substr(sha1($pass)),0,32) --1
3d4f2bf07dc1be38b20cd6e469a107:111111
md5(md5(pass)) ouble md5 --1
928da4df568e076f6767582a0570c93a5e:N4B135

It can output the hashtypes and numbers of hash.
