To use, first cd into the go_shell directory. Then run:

$ go run shell.go

You should see something like:

/path/to/directory/go_shell/ $

Type help to see a list of built in commands. Or run a program such as:

/path/to/directory/go_shell/ $ ping -c3 localhost

To run a list of commands and programs from a batchfile, first put them into a file, one per line and run as:

go run shell.go batchfile.gosh

You can even run several files sequentially.

go run shell.go batch1.gosh batch2.gosh
