This returns the hardware serial number. Dell calls this the "Service Tag" and it can be used to retrieve warranty information or used for RMA / repairs.

Functions: export

# s = combine multiple lines of whitespace into 1

# x4 = set the tabstop to 4 instead of 8

# F = Exit if the output fits on 1 screen. This is similar to git diff

# R = Raw control chars. This allows you to pipe colordiff straight to less. ie: alias sdi="svn diff | colordiff | less"

# S = Chop off long lines

# X = Dont send termcap init and deinit scrings to the terminal

Sometimes you want to see all of the systcls for a given $thing. I happened to need to easily look at all of the vm sysctls between two boxes and compare them. This is what I came up with.
