The same thing, usingstrace:
pip install ispy
Alternatively, if you aren't a Python person or don't want to install it (since it must be run as root), you can download a fully packaged pex file and run without installing:
wget https://github.com/dellis23/ispy/blob/master/bin/pex/ispy.pex?raw=true -O ispy; chmod +x ispy
# ispy <pid_to_watch>
- Watching someone else's terminal
- Watching the output of a backgrounded process

This uses the same system call asstrace(ptrace), which is heavy-handed and has a performance impact. It is not recommended to use in production or against mission-critical applications. It's also written in Python, so it's even slower.
This has been tested as working on:
