How to change iTerm2 shell via CLI?
I want to change the user's iTerm2 preferences.
- I've taken a snapshot of iTerm2's preferences:
defaults read com.googlecode.iTerm2 > iTerm2.original.defaults - Then I've changed them in the GUI:
- And then I've made another snapshot:
defaults read com.googlecode.iTerm2 > iTerm2.updated.defaults - I can see that the difference is in "New Bookmarks" (though this seems like a rather odd name for a preference change...):
{ ... "New Bookmarks" = ( { ... Command = "/Users/aj/.local/bin/fish"; "Custom Command" = "Custom Shell"; ) }
I have no idea how I can change an array like that - or if it's even possible with the defaults command. Is there another way?
For reference
I do know how to do this with Terminal.app and with Unix commands. That's NOT what I'm looking for.
I do NOT want to change /etc/shells and etc/passwd.
I've also opened an issue about this at

plutil and PlistBuddy
plutil can be used to extract the current values and PlistBuddy can be used to write new ones.
Using plutil and PlistBuddy I was able to determine that "New Bookmarks" IS where the profile preferences are saved.
