My first post here....
I have a few years exp with linux distros and some very basic Python..Ive been intent on learning shell scripting the last few weeks. Please excuse my crude efforts.
I am running a program that takes network data containing US city names in plain text. I am TRYING to write a shell scripts that will filter at the nic for specific cities (using tcpdump) and alert both on the monitor and with audio ( and eventually a text message)
Tcpdump and the filters work well however I cant figure out how to accurately display on the monitor and play the wav when a select city is found. (My audio script works well on its own).
This works for me so far...
But when I try to add an audio alert with a loop...
The above script comes back comes back positive with every pass of the loop and just prints "found at"
Can anyone give me some direction?
Thanks
Dave (hmm my indents didnt take here. I believe that all my indents are correct. Its the script that is incorrect)

I see your point. I figured that I was probably over complicating things.
Tried your suggestion exactly and the filter works well printing the city names however the "'found at' $date" does not display nor does the sound play. (Sound works fine when run independently). For whatever reason, that "then" statement does not complete??
Thanks
Dave
The returned code is the one of the last command. Maybe here it's of the 'true' at the beginning of the while loop.
Not sure that you can just grep the output of tcpdump to capture the city names.
I'm not familiar with tcpdump, but i think you should look at its manual to find another way.
Hi,
I have a variable called result that get the the below value i.e two lines assigned../logs/mymac/myserver.log:####<Jun 7, 2015 12:56:54 PM EDT> <myserver.my.bank.com> <mymac> < ExecuteThread: '5' for queue:\

This should be extremely simple and someone will probably answer it in .5 seconds. I need to know what:
VARIABLE=${0##*/}
does? I do not have a shell handy to just try it in. I am reading through some scripts and need to understand this line. Any help is appreciated.
Many thanks!

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)
Assume $x equals "".
If I try:
if test -n $x
I get the "Expression syntax" error.
It works in Linux but not in unix bash. In unix bourne I get "test: argument expected" (4 Replies)
This is probably a really simple problem, but goes easy on me I'm still a newb. The problem I have is that a script (we'll call it script.script) I edited won't run for some reason, I get the error "ksh: script.script: not found"
The location of my script is as follows: /home/users/arkitech
