Not getting the proper response from docker command about cliwrap HOT 5 CLOSED

...>createdbtestDump.sql is shell syntax, not a command line argument. You'd have to do Cli.Wrap(...) | PipeTarget.ToFile("createdbtestDump.sql") to achieve equivalent behavior.

Edit: sorry, didn't notice you were running exec, which I assume would probably allocate a shell under the hood.

To answer your questions:

Does it do this because the docker command returns an error, which in reality I would want to see, and

If there's an error (non-zero exit code), you'll get an exception using the code in your sample. If you don't get an exception, the process exited with 0.

Since you're running ExecuteAsync(), there is no stderr in the exception message. You're responsible for handling it yourself. However, you can replace it with ExecuteBufferedAsync() (which sounds like what you really want, based on your sample), and that will add the stderr data in your exception. That should help in debugging.

Is it that for whatever reason, it's not waiting for the docker command to finish before moving on to the next line in the batch file?

Not impossible. You could remove lines and isolate one command in your bat file to test.

You were absolutely correct, it was the ExecuteBufferedAsync() that I needed and I got the expected output.

Then I tried to do it in a real case, and I'm having trouble with the final parameters.

It can't seem to figure out the "createdbtest>createdbtestDump.sql" part. Output is: "Unknown database 'createdbtest > createdbtestdump.sql'" when selecting the database

However, if I just give it the dbname(createdbtest), it does dump it right into the console. Not where I want it, which is in the docker container.

It doesn't like redirecting the output to a file, is there something I'm missing, i.e. how to add the parameters correctly?

Additional note: This is likely where using a batch file works best.

I used a batch file and everything works as it should!

Well, it does really seem like whatever docker exec is using doesn't recognize the > operator. Note that > should not be part of the command line passed to the process. It should be parsed by the shell as instructions on how to deal with the output. In CliWrap's case, CliWrap is essentially the shell and the pipes are expressed differently -- i.e., through objects instead of strings.

The correct solution depends on what you're trying to achieve. If you want to pipe the output to a local file, then use PipeTarget.ToFile(...) like I explained in the previous comment (the part that is strikethrough-ed). If you want to pipe the output to a file inside the container, then you should probably do something like dotnet exec /bin/bash -c ... so that the underlying shell (bash in this case) can parse your input and execute it properly.

Exactly, but it works a treat when I use a .bat file, and I'm sure a .sh file on linux.

Thanks a LOT!
