–> execute tar on remote host sarah and send tarball to standard output,

which becomes standard input for tar xvf – and the file gets dumped locally,

in this case on crawl. you have to cd to dir before tar or else you

while [ $x -gt 0 ]





–> Something very important to remember about partitions

It is important to note that Cylinder 0 contains the disklabel, which

contains the partition table. A normal filesystem can be placed

starting at Cylinder 0, since it will not touch the disklabel.

If you lay down a raw device, for a database, over Cylinder 0,

then you will completely lose all your partitions. You will then

have to restore the disklabel, and backup from tape if you happen to do this.

–> move a partition

ndd /dev/tcp \?

ndd /dev/udp \?

ifconfig pe0 netmask up

route add default 1

verify the routing table: netstat –rn

add resolv.conf entry: domain nameserver

edit /etc/nsswitch.conf change hosts to files, dns

lesson here is to unplumb interface, and let ifconfig setup the routing.

if you specify an ip address and a netmask it will manage

the routing and the broadcasting.

–> find all, files associated with PID 22240

/usr/proc/bin/pfiles 22240

find file based on inode

find –i number

“ncheck –i number

–> good redirection example

synchronizing database dump files, binary files, etc. This is definitely a powerful tool.

–> Example Awk Script

# run with awk -f/tmp/1.awk /etc/group

{ print $1 | &#8221;sort&#8221; }

{ nlines++ }

END { print nlines }

–> awk example.

awk &#8217;/#/ {print &#8221;Got a comment&#8221;}&#8217; /etc/hosts

–> delete every 2nd field in file

awk '{$2= &#8221;&#8221;; print}&#8217; datafile >

–> awk average/standard deviation program

x2 += $1*$1


x1 = x1/NR

x2 = x2/NR

sigma = sqrt(x2 – x1*x1)

if (NR > 1) std_err = sigma/sqrt(NR – 1)

print &#8221;Number of points = &#8221; NR

print &#8221;Mean = &#8221; x1

print &#8221;Standard Deviation = &#8221; sigma

print &#8221;Standard Error = &#8221; std_err
