Hello.
I have been trying to mix the features which allows me to de-duplicate and avoid excessive lines in my history, with the 'appendhistory' variable, which somehow seems to be incompatible.
I wanted to remove all the duplicated entries after the terminal closed, so it would be far easier to search and also to keep at hand the command i use the most.
After a lot of help from the people in #zsh , i encountered a way to do this, 'externally', with a script.
In my .zshrc i have added a 'trap my_script.sh EXIT' trap, which makes the script to be ran after i close the terminal.
The script in question has the following inside:
----
#!/usr/bin/env bash
#tac ~/.bash_history | awk '!x[$0]++' | tac > .bash_h
&& mv .bash_h .bash_history --> This one
saves the last occurence of the repeated lines(commented)
awk '!x[$0]++' ~/.bash_history > .bash_h && mv
.bash_h .bash_history --> this is what i am
using at the moment.
----
So, with the default values for share_history and appendhistory, and the following line also inside .zshrc:
setopt HIST_IGNORE_ALL_DUPS HIST_IGNORE_ALL_DUPS HIST_IGNORE_DUPS HIST_SAVE_NO_DUPS HIST_FIND_NO_DUPS
I have it working.
But an user of the #zsh channel told me that this kind of script would break multi-line lines saved in the history, and i also have noticed that after running this script, some special characters becomes 'weird' into the .bash_history viewing. With weird i mean things like ＃º and ＃º ,which fortunately are not present in the terminal history (the commands are properly shown in there).
Is there some way to improve this? to make it to not break multi-line history entries, to remove the 'weird characters' from the text file and also to know if this would break my history in a random moment.
This is my first message in here so i do not know if the order of exposing it was the correct.
