'/proc/uptime' asFileReference readStreamDo: [ :stream | stream contents ]. is better way. but you will still get an empty string because actually â/procâ does not contains real filesâ¦ so the file plugin does not applies there (and is another debate if it shouldâ¦) you should use OSProcess instead (installable from Configurations Browser) (PipeableOSProcess command: 'uptime') upToEndOfFile.
