Output including non succeeded hashes?

[Perileos]

Hello,

So I'm wondering if it would be possible to have the output look like this:
e99a18c428cb38d5f260853678922e03
8f036369a5cd26454949e594fb9e0a2d
hello123
b8f8312b939f00abb38eeafd4fd107f3

Etc. Would this be possible?
If so, what code do I need to use?

Kind regards.

Couldn't you just use --remove and then merge your input and output file?

[atom]

you can simply use --show and --left and append them to each other

Issue is that if I merge them together, they're not on their original lines anymore.

[atom]

it depends! if you sort -u the original list before you can do the same with the merged file afterwards and in that case the sort -u original and merged list line positions are the same
