I can never remember any of these commands.  I know that you flip flop waring, bearded, leather patch wallahs can but heres a list they is very useful.
vmstat n – To show Virtual Machine, Disk I/O, Swap etc use.  The n makes it refresh every n seconds
/etc/sysconfig/network-scripts/ifcfg-eth1 – Use to set static interface on most Linux’s
Contents something like:
# Description of type
DEVICE=eth1
BOOTPROTO=static
IPADDR=x.x.x.x
NETMASK=x.x.x.x
ONBOOT=yes
TYPE=Ethernet

Remember to use /etc/sysconfig/network for your default gateway

NETWORKING=yes
HOSTNAME=”hostname.linux.org”
GATEWAY=”10.164.234.1″
GATEWAYDEV=”eth0″
FORWARD_IPV4=”yes”

TAR – Use extracting/imploding files to one file – does not compress
tar cvf nameoftarfile.tar -I textfile.txt – takes the contents of the text file and adds to tar
tar xcvf nameoftarfile.tar – extract and verify
Solaris and 802.1q tagged interfaces
Interfaces are usually called hostname.ceVLANID000
Adding Interfaces to Solaris – making sure they work on boot
vi /etc/netmasks – add the subnet to this
vi /etc/hosts – add the interface and VLAN
create a hostname.ceVLANID000 file
manually plumb:
  plumb eth1 (bring up L1)
  ifconfig add inet x.x.x.x netmask x.x.x.x broadcast x.x.x.x
  ifconfig eth1 up
Ill keep adding as I think of them
