BShell: the Bard Shell
BShell is a simple implementation of a Unix shell program. This was originally a lab project for my Computing Systems class at Bard college that I've continued working on for fun.
Currently implemented features:
- ls, cd
- jobs
- kill (with or without signals)
- '&' to run tasks in the background
exitto exit the shell (SIGINT (Ctrl-C) is caught and does not terminate the shell)- all shell commands that run native executables (e.g. cat, grep, tar, etc)
Features to be implemented next:
- wildcard (
*) expansion, e.g.mv *.txt .. - I/O redirection (
>and<), e.g.cat file1 file2 > file3 - piping (
|), e.g.cat example.txt | grep “keyword” - tab completion
- history
(Note this code will only run in Unix environments)
