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.
