Gosh!

Gosh is a simple shell written in Go.

Install

go install github.com/bfontaine/gosh

Dependencies

• Go 1.2 or higher
• Readline

Usage

gosh

You’ll get a prompt, from which you can execute commands like in every other shell. Use ^D or exit to exit it.

Features

Just a basic REPL, right now.

Gosh doesn’t support quotes, escaping and wildcards, nor any loop or conditional constructions.

Builtin commands

• alias L=V: add an alias L to V. V can be any command, even with spaces or weird characters. Aliases can’t be recursive.
• cd <path>: change the current directory (can contain spaces)
• echo ...: print stuff. You can insert environment variables with $var or ${var}
• quit, exit, ^D: exit the shell

~/.goshrc

If a ~/.goshrc file exists, Gosh reads it and executes it line-by-line as if it were given on the prompt.

You can use it for common aliases, e.g.:

alias ll=ls -l
alias la=ls -la

Options

Gosh currently supports the following options:

• -debug: show all errors
• -trace: show all lines are they are executed, both from the ~/.goshrc and the interactive session

Use gosh -h for more info.

Editor support

• Vim: vim-gosh
