Oh is a new Unix shell written in Go that reimagines shell design with a Scheme-inspired language featuring first-class channels, pipes, environments, and functions. It aims to fix historical flaws in traditional Unix shells while respecting established shell conventions.

Use cases

• replace bash with a modern shell language
• write shell scripts with lists and rich return values
• use a shell with lexical scope and exceptions
• script with first-class channels and concurrency
• define new shell language constructs with fexprs

When to choose

• you want a more regular, powerful shell language than POSIX shells
• you need lists, lexical scope, and rich return values in shell scripts
• you like Scheme-style languages for scripting

When to avoid

• you need full POSIX/bash compatibility for existing scripts
• you need a shell with a large community and ecosystem
• you want a shell that is actively and rapidly developed
