Welcome to the Robert-Martin Simple Shell Project this shell can be compiled and run from the command line, it includes basic features, as well as some advanced features found in most shell programs.
The prototype of our main function is as follows:
int main(int argc __attribute__((unused)), char **argv, char **env);The header file is called holberton.h where all the function prototypes, structures and libraries used in our shell are referenced.
- git clone this repository to your local machine.
$ git clone https://github.com/sebascastel/simple_shellcdintosimple_shell/directory.
$ cd simple_shell/- Compile the program.
$ gcc -Wall -Werror -Wextra -pedantic *.c -o hshor
$ make - Execute the Shell's Bells !
$ ./hshNote: Shell's Bells can also be run in non-interactive mode:
$ echo "/bin/ls" | ./hshThis Shell, has a familiar syntax when running commands, as other common Shells:
†Shell's Bells† <command> <flags>- non-interactive mode:
$ echo "<command>" | ./hshinteractive mode
lscommand:
†Shell's Bells† ls -1pwdcommand:
†Shell's Bells† pwdcdcommand:
†Shell's Bells† cd ..helpcommand:
†Shell's Bells† help <builtin command># comments
†Shell's Bells† echo Hello # World

exit - exits the Shell
env - prints the environment variables.
setenv - sets an environment variable.
unsetenv - unsets an environment variable.
