ZSH alias for grep'ing the history command easily

gistfile1.txt

# in your .zshrc add:
alias HG='history | grep '
 
# reload ZSH (using my default location as an example)
. ~/.zshrc 
 
# Now run: ``HG something_of_interest`` and your history is grepped for said interesting something.

Thanks. I was trying like history | grep "$1". But your method is simpler
