Merge two zsh history files

thanks!

zsh can do this itself:

    builtin fc -R -I "$hist_file"
    builtin fc -R -I "$another_hist_file"

    # write the loaded history to HISTFILE
    builtin fc -W "$HISTFILE"

This was exactly what I needed. Thanks for sharing!

Sweet! Thanks to both of you for providing options. I went with the builtin solution and it worked great.

@NightMachinery This is great and works when I paste it to a terminal manually, however, it doesn't work for me when I create a script like merge-zhs-histories.sh. I tried this:

#!/usr/bin/env zsh

hist_file_1="/Users/borekb/.zsh_history"
hist_file_2="/Users/borekb/.zsh_history (1)"
hist_file_merged="/Users/borekb/.zsh_history-MERGED"

builtin fc -R -I "$hist_file_1"
builtin fc -R -I "$hist_file_2"

builtin fc -W "$hist_file_merged"

The .zsh_history-MERGED file is not created for me (but it is created when I copy/paste the code to my terminal).

Is that something specific about builtin fc? Or am I making some obvious mistake?
