@j0k4rX just take the command value into a bash file, make the file executable, and put the file into a directory inside your $PATH (so you can call it everywhere from your shell) or where ever you like, then change the command value to the path of your script.
For me, i created a bash script called getgithost and put it inside ~/.local/script, so my command variable look like this
command = "~/.local/script/getgithost"

@fitrh can you be more specific?

should i add this line in .bashrc
command = "~/.local/script/getgithost"

and the getgithost is the file name or getgithost.bashrc something like this under ~/.local/script

should i add this line in .bashrc
command = "~/.local/script/getgithost"

no, it's for your starship config

and the getgithost is the file name or getgithost.bashrc something like this under ~/.local/script

just the getgithost

replace this
