Worldlist Clean up

Hello all, 

I been trying to figure this out for the last hour. I looked online but can't figure it out... I know it's going to be simple command ugh... I have a small file that I like to clean up that has hashes with password. The problem is that there's a space between the hash and password or it has ":" symbol. How do I remove the hash and keep the password. 

Here's an example 

10d21373467d23b7feeec8cfb4dac01a password1        < - no space

1b9c2625dc21ef0540wo4ddf47c5f203837aa32c:ilovelinux      < - has the : after password. 


Thanks, 


Other thing if you have any more command you like to share when cleaning up a wordlist please feel free to share it. 

thank's again.
