Hashcat SHA1 output "hash:plain" to plain

Hello everybody,

I had cracked a combo list 500MB with SHA1 hash, i forgot to select format to only plain.
How I can convert the output file from:

892fffd8cf61c65480a3d082c7e3e3d5e1e5daa6:epcc0589
.........
to

epcc0589
.........

I need only passwords, think there is any Linux command like SED or CUT.
Thanks for help and Good Night everyone !
