Group commands to run in background

[Kumarappan Arumugam]

Is there a way to call a group of commands to execute in the background like a sub-shell?

For example:

@sh(_bg=True)
def build():
    sh.rm('something')
    try:
        sh.yarn.build() # long running process
    except:
        sh.yarn.build_without_cache() # long running process
    sh.mkdir('something')
    sh.find('something')

procs = []
for dir in all_dirs:
    procs.append(build()) # parallel
[p.wait() for p in procs]

I know I can manually fork another child process, but was trying to figure out if I can do something with the existing functions in the sh.py.

There isn't, no. It is an interesting idea, but to do what your code snippet suggests would require implementing some kind of process-coordinator that is outside of the scope of sh.
