Zsh’s history feature is a powerful tool for programmers and system administrators. It allows users to recall previously executed commands, saving time and reducing errors. This can be particularly useful in complex programming tasks or repetitive administrative duties.
The ‘history’ command displays the list of past commands, while ‘!n’ recalls the nth command. The ‘fc’ command lets you edit previous commands before executing them again.
For instance, if you’ve run a long script with multiple parameters, instead of retyping it, you can simply pull it from history. Similarly, if you’re troubleshooting an issue that requires running similar commands repeatedly, using history can speed up this process.
Moreover, Zsh supports shared history across all active shells. This means any command entered in one terminal will be immediately available in all other terminals. This is beneficial when working on multiple tasks simultaneously.
