Thank you Nik!,
Is there any difference to using?:
if [ "$(pidof twin)" ]; then echo "TDE RUNNING"; fi
It seems to work the same, but I ask ‘cause there a tons of hidden ‘gotchas’
that aren’t ever really documented.
Would one of the TDE dev’s be so kind as to point me in the right
direction on how to do that (the uninstall process runs as sudo)?
if [ ! -z "$(pidof twin)" ]; then echo "TDE RUNNING"; fi
Best,
Michael
