Hi
Well as the title says -- is it?!?
...and more to the point HOW 
tried:
· if RunCommand('mount',['/proc'],aResult) then ...
· if RunCommand('/bin/sh',['mount','/proc'],aResult) then ...

Both to no avail... 
N.b.: Yes I'm running the app as root ~ su
TIA
Regards Benny

There no path then have use full path mount. also have one parameter
(have need 2) ? https://www.geeksforgeeks.org/linux-unix/how-to-mount-
and-unmount-drives-on-linux/

Quote· if RunCommand('/bin/sh',['mount','/proc'],aResult) then ...
man sh

Have option -c, then have single parameter but have combine all
argument for -c.

Have look aResult and have error.

PS: https://wiki.freepascal.org/Executing_External_Programs#(Process.)
RunCommand example first, make replace bash and have use sh (and mount
and no echo but echo good for test)

I suppose you don’t just want to mount /proc and that’s your entire
program. You probably want to access some files. Beside the issue that
a plain mount /proc refers to /etc/fstab (which may or may not contain
an appropriate entry), have you looked into whether e. g. the baseUNIX
unit already contains a function exposing the information you seek in
a structured format? This would eliminate the design flaw that your
program needs elevated/mount privileges (unless you’re doing other
root stuff, too).

Are you on an (linux) OS that does not automatically mount /proc ?  I
have not come across one to be honest.

Hmm, PC Linux ....

Hi Davo
We've had a slight /glitch/ in 'grub2' that managed to somehow
suddenly 'unmount /proc', so we've had to step back a version of
'grub2'...

But it's a lengthy process to debug / test an app, when you don't know
when the condition that should trigger it, actually happens  ...if it
does happen at all 

Happy holidays mate, to you and you family \o/
