This is a simple Shell based on the Sh Linux shell. It executes commands given by the user or from a file.
You can compile the source files using $ gcc -Wall -Werror -Wextra -pedantic -std=c90 *.c -o hsh
The shell can operate in two modes, interactive and non-interactive.
In the interactive mode, you run it by typing ./hsh and then typing your command when the prompt appears, finishing with the enter key. To exit the console in this mode, you can use the exit command or hit control + D.
In the non-interactive mode you can use a pipe to make the shell execute just one command, for example: echo ls | ./hsh will make the shell execute the ls command and go back to your current shell.
Also, you can use ./hsh file To execute a set of instructions from file.
