How do I connect a found hash to plain:hash?

[LackuJacku]

My question is how do I connect a found hash:

8743b52063cd84097a65d1633f5c74f5:test1

with a plain:hash that it originally came from:

blahblah:8743b52063cd84097a65d1633f5c74f5

to make:

blahblah:8743b52063cd84097a65d1633f5c74f5 + 8743b52063cd84097a65d1633f5c74f5:test1 = blahblah:test1

basically matching the hashes together...

I remember vaguely there was a command to do something like this, but I honestly don't know. Can anyone help me?

hashcat -m [hashmode] --potfile-path [pot.pot] --show --username --outfile-format=2 [input]

hashcat -m [hashmode] --potfile-path [pot.pot] --show --username --outfile-format=2 [input]

Bro thank you so much I have been searching forever!
