Describe the bug

Most of the utilities I've tried give the following syntax error on this distro:

[gwatts@SurfacePhoto ~]$ wslfetch
/usr/bin/wslfetch: line 245: "15" / 8 : syntax error: operand expected (error token is ""15" / 8 ")
/usr/bin/wslsys: line 245: "15" / 8 : syntax error: operand expected (error token is ""15" / 8 ")
/usr/bin/wslsys: line 245: "15" / 8 : syntax error: operand expected (error token is ""15" / 8 ")
 /$$      /$$  /$$$$$$  /$$       Windows Subsystem for Linux (WSL)
| $$  /$ | $$ /$$__  $$| $$       gwatts@SurfacePhoto

| $$/$$ $$ $$|  $$$$$$ | $$       Branch: ni_release
| $$$$_  $$$$ \____  $$| $$       Release: CentOS Linux 7 (Core)
| $$$/ \  $$$ /$$  \ $$| $$       Kernel: Linux 5.15.90.1-microsoft-standard-WSL2
| $$/   \  $$|  $$$$$$/| $$$$$$$$ Uptime (Windows): 0d 1h 3m
|__/     \__/ \______/ |________/

It seems like it is still doing what it is supposed to be doing, however (opening a url, etc.).

Steps to Reproduce

sudo yum-config-manager --add-repo https://download.opensuse.org/repositories/home:/wslutilities/RHEL_7/home:wslutilities.repo
sudo yum install -y wslu
wslfetch

Expected behavior

THe output of wslfetch as shown above, but without the syntax errors.

Additional context

Many thanks for the utilities!!

can you show your bash version?

[gordonwatts]

Yep - that is it! On an old container where most of our work still continues in the experiment, and this bug shows up:

[gwatts@AMDOfficeCore ~]$ bash --version
GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)
Copyright (C) 2011 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

And on a new one that we will move to over the next 5 years (and where it works):

[gwatts@AMDOfficeCore ~]$ bash --version
GNU bash, version 5.1.8(1)-release (x86_64-redhat-linux-gnu)
Copyright (C) 2020 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

What is the limit of where it works?

This should be suggested to be used with bash 5
