Linux tips: see machine HW config

Virtual directory /proc holds virtual files :

version

mounts

modules

meminfo

filesystems

driver

devices

uptime

stat

scsi

etc...

... and virtual dirs per all running processes.

To see the values just "cut" the corresponding file, e.g.

$ cat /proc/version
