You're sections headers will be used to reference location of destination.
The goal of this project is to create a simple shell. Will be your own little bash or zsh. You are going to learn a lot about processes and file descriptors.
- Find and launch the appropriate executable.
- Builtins:
- echo (-n flag included)
- cd (with absolute and relative path)
- pwd
- export
- unset
- env
- exit
- ; will have to separate the commands on the command line.
- Redirects >, “>>” y < should work as in bash, except in fd aggregations.
- Environment variables ($ followed by characters) should work like in bash.
- Pipes | should work like in bash.
- $? it should work like in bash.
- ctrl-C, ctrl-D y ctrl-\ should show the same result as in the bash.- malloc
- free
- write
- open
- read
- close
- fork = Creates a child process.
- wait, waitpid = Stops the parent process until the child process exit.
- wait3, wait4 = Are similar to waitpid, but additionally return resource usage information about the child.
- signal = Sets a function to handle a signal.
- kill = Sends a signal to a process or a group of processes.
- exit = Terminates a process immediately, special handle for child processes.
- getcwd = Saves the pathname of your current working directory in a string.
- chdir = Changes your current working directory.
- stat, lstat, fstat = Returns information about a file.
- stat = Standar.
- lstat = For symbolic links.
- fstat = Gets the file from a file descriptor.
- execve = Executes a program referred by a variable.
- dup = Creates a copy of a file descriptor using the lowest numbereded unused descriptor.
- dup2 = Creates a copy of a file descriptor using the descriptor number given by the user.
- pipe = It's used to create inter-process communication.
- opendir = Opens a directory stream.
- readdir = Returns a pointer to a dirent structure representing the next directory entry in the directory stream.
- closedir = Closes the directory stream.
- strerror = Returns an error message.
- errno = Number of last error, its a variable.
