I ran this command

history | cut -c 8-

It listed all the history commands as expected without line numbers.

I'm wondering if there is a way to list only unique one.

I've tried

history | cut -c 8- | sort -u

doesn't seem to work.

To get the names of the commands only, you can use this:

history | cut -f4 -d | sort -u

Or for better results, you can use this:

history | sort -u -b -k2,2
