External Email - Use Caution        

The output shows the command running on Ubuntu 18 linux and getting an error 
from the shell for a bad file descriptor (fd),Linux holowach 5.3.0-53-generic 
#47~18.04.1-ubuntu SMP Thu May 7 13:10:50 UTC 2020 x86_64 x85_64 x86_64 
GNU/Linuxsh: 1: Syntax error: Bad fd numberThat could be an issue with the 
shell on Ubuntu.   On Ubuntu the default “sh” in PATH,
$ which sh/bin/sh
- is usually a soft link to the minimal “dash” shell and not a more complete 
shell like the “bash” shell.
$ ls -l /bin/shlrwxrwxrwx 1 root root 4 Jan 
3  2020 /bin/sh -> dash*

I would try using the bash shell, e.g., type “bash” in your terminal window and 
then run the command that produced the error,
$ bashyourhostname[0]:~$… run your command ...
If that fixes the issue, you might consider changing the /bin/sh link to point 
to bash instead of dash.  But you will need sudo/root privileges to do 
that, e.g.,
$ cd /bin$ sudo rm sh$ sudo ln -s bash sh
- R.
