DEMO TO MULTIPLE TERMINALS
Ever want to show multiple
people what you are doing in
a shell.
In the shell doing the demo
type:
% csh -i |& tee /tmp/demo
or
$ csh -i 2>&1 | tee /tmp/demo
In the other shells that are
going to watch the demo type:
% tail -f /tmp/demo
That's it!

Unix Tip: CUT FROM STANDARD COMMANDS

UNIX HOT TIP
Unix Tip 3491 - August 30, 2012
http://www.ugu.com/sui/ugu/show?tip.today
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
CUT FROM STANDARD COMMANDS
To properly cut the output of
unix standard commands; such
as ls, ps; and properly handle
them without all the extra
spaces, use this:
% ls -lt| tr -s " " | cut -f6-10
% ls -lt| tr -s " " | < --do what ever-- >
tr -s " " ==> here tr in
effect removes all the extra
formatting extra spaces
introduced by unix shell,
for display, and translates
in to format easy to work
with.
If we dont use this tr, then
the -c option of cut will be
unreliable because of varying
size field lengths in the
output and also -f option
will be unreliable because of
extra formatting delimiters.
ls -lt | tr -s " "
ps -ef | tr -s " "
gives us proper output to
properly extract data or
columns.

PROTCOLS WITH NETSTAT
Use the command:
% netstat -an
It will show you what ports
are in use on the local and
foreign machines as well as
the protocol running over that
port for that connection and
IP address information. It
also displays the state of
the socket being used.
Using the above tip user can
identify the port to which he
wants to send data is busy
or free.

Unix Tip: GEEK DECODER RING

UNIX HOT TIP
Unix Tip 3486 - August 25, 2012

GEEK DECODER RING
Ever want to sneek some not
quite politically correct
witticism or other thought
past the "non-technical"?
Or maybe you just want to
un[en|de]code bits, hex or
uu text (boring, but more
practical).
Here's some simple perl
code you can use for a
geek/nerd/dweeb "decoder
ring":
ENCODE INTO BITS, HEX, UU:
perl -ne'$b=unpack("b*",$_);@l=$b=~/.{0,56}/g;
print(join("\n",@l))' <<RM
Tron rules!
RM
Just change the "b*" to "h*"
for hexidecimal or "u*" for
uuencoding.
DECODE FROM BITS, HEX, UU:
perl -ne'chomp;$a.=pack"b*",$_;END{print"\n$a\n\n"}'<<RM
00101010010011101111011001110110000001000100111010101110
00110110101001101100111010000100
RM
I include my favorite
messages that I otherwise
might not write out in clear
text in my signature file along
with the decoder code. It's
enough to scare away most. But,
I've found those technically
superior types get more of a
kick out of "decoding" (cut
and paste to UNIX/LINUX
command line) the message
during their more productive
moments. ;-)
