How to remove an entry from the history in ZSH

Question

Let's say I ran a command using a zsh

echo "mysecret" > file

I can easily print the history including the entry numbers using the command fc -l:

1  echo "mysecret" >| file 

But how can I easily delete an entry from the history?

I cannot find a corresponding paragraph in man zshbuiltins.

*BSD/Darwin (macOS):

LC_ALL=C sed -i '' '/porn/d' $HISTFILE 

Linux (GNU sed):

LC_ALL=C sed -i '/porn/d' $HISTFILE 

This will remove all lines matching "porn" from your $HISTFILE.

With setopt HIST_IGNORE_SPACE, you can prepend the above command with a space character to prevent it from being written to $HISTFILE.

As Tim pointed out in his comment below, the prefix LC_ALL=C prevents 'illegal byte sequence' failure.
