Unable to get exit code on cp/rsync

[zzzbatmand]

I want to see if a cp/rsync fails, but when I try to use $? after the command has failed (sys.exit(2)) then I just get a 0.

OS: Windows WSL

me@PC:/mnt/c/Users/me/Documents/TMP/fw# rshell -p /dev/ttyS7 cp -r ./Pycom/* /flash
Using buffer-size of 32

Sidenote:
The way I tested this, was by disconnecting the serial wires doing upload.
Sometimes this caused the program to just hit an infinite loop.

Same on Ubuntu – this is a major bummer for me because I use this in scripts with set -o errexit and wrongly assumed the whole thing was successful when rshell cp had actually failed somewhere further up in the script.

Thanks for bring this up. This isn't a path I had considered. I'll see what I can do to fix this.

I think I've fixed it so that if that if you do rshell some-command and some-command encounters an error then the exit code will be non-zero (in version 0.0.36)

Thank you! I'll be working with this in the upcoming week and will report back!
