Output qgis_process Command Line Results on the Terminal

[Dan-Eli]

QGIS 3.14 comes with a very interesting new features qgis_process which is a new standalone console tool for running processing algorithms.

I tested this new tool, it's working well but the first time I used it, I tought it was not working as it displayed nothing on the screen. Only after I requested to redirect the output: StdOut and StdErr to a file that I was able to see the results by printing the content of the files.

qgis_process list >stdout.txt 2>stderr.txt

qgis_process will be used a lot by organizations that need to automate and batch geo spatial processing. It would be very useful that output (stdout and stderr) are sent directly on the terminal.

Note: This behaviour was tested on Windows 10, I do not know if it's the same on Mac or Linux

@Dan-Eli, I think this is a bug on Windows OS.
On GNU/Linux (Ubuntu 20.04) the output of e.g. qgis_process list is directly displayed in the terminal window, while I can confirm that it is not displayed on Windows 10 using the OSGeo4W Shell as you already reported.

It's also the same thing for qgis command line which I understand is not used very often

C:\OSGeo4W64\bin\qgis-bin.exe --version

Nothing is displayed on the screen

C:\OSGeo4W64\bin\qgis-bin.exe --help

Will pop up a new window on the screen

This is true also for prior to QGIS 3.14 and on Windows

@Dan-Eli maybe because is a brand new functionality :)

@gioman, In my last post I was not talking about the new qgis_process tool but I was talking about C:\OSGeo4W64\bin\qgis-bin.exe, the QGIS command line which is there since a very long time but not use very often in command line mode
