ZSH iterm2 increase number of lines history

Question

Not sure if this is zsh, iterm2 or the interaction between them. Trying to change the number of recallable lines in the terminal - not the command history, the output history.

Answer 1

It's not immediately obvious in the iTerm2 documentation on how to change it.

• open the iTerm2 preferences ⌘ + ,
• select the Profiles tab
• then select the Terminal subtab
• Beware, changes to the Scrollback lines value take effect immediately so check Unlimited scrollback now if you don't want to delete your current buffer(s)
• change the value of the Scrollback Lines to whatever you'd like
• Uncheck the Unlimited scrollback option if you'd like to use your Scrollback lines value
