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?
@borekb I assume these only work in an interactive shell
edit: yep: https://zsh.sourceforge.io/Doc/Release/Shell-Builtin-Commands.html
I tried the builtin fc
method mentioned above but it doesn't sort the output! So in the resulting history you get all of one file first then all of the other file. Apparently zsh doesn't care that the timestamps are out of order and doesn't sort them. But the awk solution worked great for me!
Thanks, I was getting error with merge_history.sh:
awk: towc: multibyte conversion failure on: '�`|:"' ()[]{}<>\t"'
builtin worked like a charm. Thanks
Thank you!
Thanks to both of u guys
thank you, nice!
zsh
can do this itself:
