Command output isn't shown in terminal after execution #16

Closed 29jm closed 3 years ago

29jm commented 3 years ago

Steps to reproduce:

in the terminal app, enter ls
the terminal shows a new prompt but no output from the above command

The output is only accessible via the log command within SnowflakeOS, or via the serial.log file on the host machine.

This requires changes to the way programs are executed from other programs, i.e. the exec system call, to fix this properly. I haven't thought about it long enough yet, discussion appreciated!

Closed by f426ba00fc5905b0c91e28b8edfaef6c78f52cfd. A fair bit of cleanup to do, notably making pipes a proper concept, usable from userspace, and having a way for the program that calls execs to wait termination, while printing output. Right now programs started from the terminal have a behavior similar to those started as prog& in a bash shell for instance.
