On my system product_family would be the better choice.

chrko@ThinkPad-X230:~$ cat /sys/devices/virtual/dmi/id/product_name 2325CN3 cat /sys/devices/virtual/dmi/id/product_family ThinkPad X230

I used the same file used by applications like neofetch to show the host name. I tried with an MSI and a Mac Mini and product_name and the results are these:

cat /sys/devices/virtual/dmi/id/product_family PS cat /sys/devices/virtual/dmi/id/product_name PS63 Modern 8SC cat /sys/devices/virtual/dmi/id/product_family Macmini cat /sys/devices/virtual/dmi/id/product_name Macmini6,2

While on an Asus laptop the situation is as your:

cat /sys/devices/virtual/dmi/id/product_family VivoBook cat /sys/devices/virtual/dmi/id/product_name X510UQR

So, I thought that a possible solution could be if product_family is a substring of product_name then only the latter is shown, otherwise both the strings are displayed.

What do you think?

Yeah, try it.

Let me know if it works also in your system

It works.

Thank you very much, this is helpful! But what happens if you execute a program like neofetch on your NUC server? What is shown near host label?

yubiuser · 2022-10-21T14:06:27Z

Why don't we use the same logic as neofetch

Including the cleaning: https://github.com/dylanaraps/neofetch/blob/ccd5d9f52609bbdcd5d8fa78c4fdb0f12954125f/neofetch#L1361-L1374

yubiuser · 2022-10-21T14:18:25Z

That's interesting. Currently the ~~latest code (v7.1.0)~~ master looks like

            if [[ -d /system/app/ && -d /system/priv-app ]]; then
                model="$(getprop ro.product.brand) $(getprop ro.product.model)"

            elif [[ -f /sys/devices/virtual/dmi/id/board_vendor ||
                    -f /sys/devices/virtual/dmi/id/board_name ]]; then
                model=$(< /sys/devices/virtual/dmi/id/board_vendor)
                model+=" $(< /sys/devices/virtual/dmi/id/board_name)"

            elif [[ -f /sys/devices/virtual/dmi/id/product_name ||
                    -f /sys/devices/virtual/dmi/id/product_version ]]; then
                model=$(< /sys/devices/virtual/dmi/id/product_name)
                model+=" $(< /sys/devices/virtual/dmi/id/product_version)"

            elif [[ -f /sys/firmware/devicetree/base/model ]]; then
                model=$(< /sys/firmware/devicetree/base/model)

            elif [[ -f /tmp/sysinfo/model ]]; then
                model=$(< /tmp/sysinfo/model)
            fi

Producing LENOVO 2325CN3

Using the locally installed version (also v7.1.0) 2325CN3 ThinkPad X230

And the code looks like

            if [[ -d /system/app/ && -d /system/priv-app ]]; then
                model="$(getprop ro.product.brand) $(getprop ro.product.model)"

            elif [[ -f /sys/devices/virtual/dmi/id/product_name ||
                    -f /sys/devices/virtual/dmi/id/product_version ]]; then
                model=$(< /sys/devices/virtual/dmi/id/product_name)
                model+=" $(< /sys/devices/virtual/dmi/id/product_version)"

            elif [[ -f /sys/firmware/devicetree/base/model ]]; then
                model=$(< /sys/firmware/devicetree/base/model)

            elif [[ -f /tmp/sysinfo/model ]]; then
                model=$(< /tmp/sysinfo/model)
            fi

They added it here: dylanaraps/neofetch#1943

The old was more useful I think. We could simply change the order of if cases

FauFra · 2022-10-21T14:23:32Z

I noticed the same thing. If you download the last release code, it is different from the one in the repo.

However the same logic can be implemented without any problem, but that cleaning string way is not supported in sh. Is there any reason why sh is used instead of bash?

yubiuser · 2022-10-21T14:31:26Z

Is there any reason why sh is used instead of bash?

To increase POSIX compliance to make it more portable.

${name/foo/bar} -- you can use $(printf '%s\n' "$name" | sed 's/foo/bar/'), after changing shell patterns to regular expressions. This originated in ksh93 and is also present in mksh, and zsh, but variation in behaviour and glob pattern syntax between the three.

FauFra · 2022-10-21T14:34:21Z

Okay, thanks. I will try to implement the same logic and string cleaning then.

yubiuser · 2022-10-21T16:19:49Z

Works good for me. Maybe @DL6ER could test on his devices.

Stickler test (actually Shellcheck) is complaining here. It is asking to use this variable substituion ${variable//search/replace}, but I'm almost sure this is not POSIX.

You can try to use shell "pattern filtering":

Suggested change

sys_model=$(echo "$sys_model" | sed -e 's:To be filled by O.E.M.::g')

sys_model="${sys_model#"To be filled by O.E.M."}"

Thanks! This is a more elegant way to clean the string.

This only works if the searched string is on the beginning of $sys_model. If you need to remove from the end, use ${sys_model%"To be filled by O.E.M."}

Okay, so for each string there must be two filters, one for the beginning and one for the end since there might be the possibility that the value of sys_model is To be filled by O.E.M. To be filled by O.E.M., as shown by @DL6ER

There is one more test failing (if you click on "Details" on the failing test you will be able to see it).

There are trailing spaces here.

Oh, thanks. Now it should be fixed.
