| This is a very brain dead shell. It needs some love, coffee or perhaps beer. |
| Currently, you can't even really call it a shell, its more of a CLI that |
| offers some shell like creature comforts. |
| |
| This was written in a hurry to provide some means of testing persistent file |
| systems in HelenOS. It does its job, its nowhere near complete but it is |
| actively developed. If your reading this, its likely that you're looking for |
| some functionality that is not yet present. Prior to filing a bug report, |
| please make sure that what you want is not on the list below. |
| |
| A list of things to do: |
| ----------------------- |
| |
| * cmds/modules : ls_scope and rm_scope are basically carbon copies of each |
| other, put this in util.c and make it a shared function. |
| |
| * rm: add support for recursively removing directories and files therein |
| |
| * Better sanity checking in modules that take multiple arguments |
| |
| * Port an editor (vim?) |
| |
| * Finish cat |
| |
| * Feed task_spawn absolute paths if path doesn't begin with / |
| |
| * Some getopt / getopt_long implementation |
| |
| * Support basic redirection (i.e ls > foo.txt) |
| |
| * Expand wildcards (i.e. *.txt), don't worry about variables for now |
| |
| * Basic scripting |
| |
| * Hash previously found commands |
| |
| * Improve input, add history / etc (port libedit?) |
| |
| * Add wrappers for signal, sigaction to make ports to modules easier |
| |
| * Add 'echo' and 'printf' modules. |
| |
| Regarding POSIX: |
| ---------------- |
| POSIX is a standard for Unix-like operating systems. HelenOS is (mostly) just |
| a kernel at this point with a few userspace programs that facilitate testing |
| of the kernel and file systems. |
| |
| HelenOS is not a Unix-like operating system. HelenOS is its own thing, a modern |
| microkernel OS and many directions are not yet set. |
| |
| Please do not e-mail me to point out that modular implementations that resemble |
| typical core utilities do not conform to some POSIX standard, these are temporary |
| and serve the useful purpose of testing persistent file systems. |
