giosh (generic IO shell) is a multipurpose command line shell written in Go.

giosh is not:

* a POSIX compliant shell

* a shell language with multi-line lexical scope

* a virtual machine with a new (environmental) variable declaration mechanism

# Supported features

* Command invokation with PATH resolving

* pipe

# Usage

1. Simply invoke it. You can use giosh with interactive mode. 

```shell

$ giosh

@G[1]> ls -l | grep m | sed -r -e s/.+[[:blank:]]//g

README.md

cmd

main.go

```

2. Read giosh script 

```shell

$ giosh some_script

```

3. Read an oneliner from the standard input

   (Standard input for giosh must be an oneliner)

```shell

$ awesome_script | awesome_command | giosh

```

# Limitation

At now, giosh is released under limitations (really so limited in the function).

Following mechanisms are not supported:

* comment line

* escape character \\ 

* arrow keys and command history 

* redirection with file descriptor

* hear strings or hear document

* variable declaration

* variable reference (env value is not directly available)

* variable expansion and command replacement

* background jobs (&)

* builtin commands
