my-shell

Very simple shell implementation.

I wrote this project quickly to just learn how shells work at a basic level.

Once I learned what exec and fork were it was pretty obvious what the basic model of shells were.

I might add more features in the future but currently in my-shell you can:

run any command in your $PATH
use '.' as directories
exit with: exit, Exit, bye, or e
change directories with cd (including home using ~)
enter empty command
report return code of commad

Planned features:

time (maybe)
aliases
- format (for now?): 'alias>gstat>git diff'
- parsing steps:
  - check if first part of string is 'alias'
  - add gstat to global list (in memory) of aliases
- when the command is entered, first check if it matches any of the aliases, if not the run it as normal
- if it is in the list of aliases, convert that string the same we do of buf
sigint hanlder to exit gracefully
