On Windows, in the Task Manager it is possible to see the command line of each processes but it is truncated.
How can I see the complete command line of each running process?
In cmd, run the following:
wmic process get processid,commandline
To filter for a particular program:
wmic process where "name like '%chrome%'" get processid,commandline
The other properties that you can query for processes are:
Open the properties dialog of the process in order to view the command line. In the case of Process Hacker, you can even add a column for the command line so that you don't have to open the properties dialogue box.
