A simple UNIX command interpreter that reads commands from standard input and executes them.
Use,
gcc @flags *.c -o hsh
to compile all .c files in the repository and,
./hsh
to run the resulting executable.
hsh can be invoked non-interactively. If hsh is invoked with standard input not connected to a terminal, it reads and executes received commands in order.
Example:
$ echo "/bin/ls" | ./hsh
hsh main.c shell.c test_ls_2
$
$ cat test_ls_2
/bin/ls
/bin/ls
$
$ cat test_ls_2 | ./hsh
hsh main.c shell.c test_ls_2
hsh main.c shell.c test_ls_2
$If hsh is invoked with standard input connected to a terminal (determined by isatty(3)), an interactive shell is opened. When executing interactively, hsh displays the prompt $ when it is ready to read a command.
$ ./hsh
($) /bin/ls
hsh main.c shell.c
($)
($) exit
