run.net.sh won't work in cron

I can manually run script run.net.sh but script won't work in cron.
I got "DotNet required, but it's not installed" error.
Any idea how to fix this?
Maybe to put absolute path to dotnet in run sh.script?

After that I have this error:
* You intended to execute a .NET program:
The application '/mnt/usb/webgrab/.wg++/run.net.sh' does not exist.
* You intended to execute a .NET SDK command:
It was not possible to find any installed .NET SDKs

My dotnet --info:

Host (useful for support):
Version: 5.0.17
Commit: 6a98414363

.NET SDKs installed:
No SDKs were found.

.NET runtimes installed:
Microsoft.NETCore.App 5.0.17 [/root/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET runtimes or SDKs:

i did a few tests and i think u installed dotnet manually.
when u do this u must add dotnet to your $PATH variable,see the dotnet install docs.

create a new sh script(dotnet.sh for example) and put this inside,edit the paths to your dotnet,webgrab dll and config folder.
on my nas i use custom paths for everything,its how i run it.

#!/bin/sh

export DOTNET_ROOT=/opt/dotnet
export PATH=$PATH:$DOTNET_ROOT

dotnet /raiddata/0/NAS_WebGrab/dotnet/WebGrab+Plus.dll /raiddata/0/NAS_WebGrab

exit

run this sh file in crond.

I was installing dotnet manually.

I was trynig your script but I still have error:
* You intended to execute a .NET program:
The application '/mnt/usb/webgrab/.wg++/run.net.sh' does not exist.
* You intended to execute a .NET SDK command:
It was not possible to find any installed .NET SDKs.
Install a .NET SDK from:
https://aka.ms/dotnet-download

Do I need to install .NET SDK?

nope.just the runtime is all you need which u have installed.
the DOTNET_ROOT path above is the path to the dotnet folder only not the path to the dotnet binary itself.

also in terminal if you enter these lines(one at a time,make sure your path to your dotnet folder is correct)

export DOTNET_ROOT=/opt/dotnet
export PATH=$PATH:$DOTNET_ROOT

then
echo $PATH

you should see the path to your dotnet folder listed.

which dotnet

this should return the same path

run.net.sh should work now as it uses the which command to check it dotnet is installed.

/root/dotnet
this is the correct path

/root/dotnet/dotnet
this is the path to the binary itself which is incorrect

you can fix this manually,i dont know where your $PATH variable is stored(it depends on what linux distro you use)

for ubuntu its /etc/environment
edit this file and remove the /root/dotnet/dotnet path
i dont know how linux knowledged you are put the paths are separated by a :
you should be able to figure it out how to fix it.

it should look like this
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/dotnet

edit your run.net.sh file and before the which dotnet command add

export DOTNET_ROOT=/root/dotnet
export PATH=$PATH:$DOTNET_ROOT

are u running your crond as root or a user(i already asked this)
since dotnet is installed in /root users may not have permission to access this

in your crond try
* * * * * root /path/to/run.net.sh
edit the * * * * * to whatever u want

I think that is the solution:

**********
edit your run.net.sh file and before the which dotnet command add

export DOTNET_ROOT=/root/dotnet
export PATH=$PATH:$DOTNET_ROOT
**********

Now cron job is working ok.

Thank you for helping me to resolve this problem.
