No, it isn't.

Hi,
Does anyone know a simple way to check if a Linux process exists/runs
(child or not) *without* running an OS command via TProcess (or other)?
Thanks.

How do you want to identify this process? By name, by pid, ...?

You can read all the /proc/%d/cmdline files to search for a specific process.

How do you want to identify this process? By name, by pid, .
While scanning /proc may not be portable, the question asked is about checking
for a running Linux process. The only way I know is scanning all directories
within /proc (which as you all know are the id's of the running processes)
and checking for the process file name and the process command li

Shucks :-) I remember that JPI v1 had what they called "virtual
