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 know this is a total begginer question but what is wrong with this picture. My loop wont loop, it just drops me back to the prompt and gives the error "unary operator expected". Any help would be appreciated.

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

If I try:

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)
Hi everyone.
I am new to shell scripting and have been looking at quite a few web pages to try and figure this out, but to no avail.

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!

driftnet
DRIFTNET(1) General Commands Manual DRIFTNET(1)NAME
driftnet - capture images from network traffic and display them in an X window; optionally, capture audio streams and play them.
SYNOPSIS
driftnet [options] [filter code]
DESCRIPTION
Driftnet watches network traffic, and picks out and displays JPEG and GIF images for display. It is an horrific invasion of privacy and
shouldn't be used by anyone anywhere. It has been described as `a graphical tcpdump(8)', `EtherPeg for Unix', and called all sorts of nasty
names by people on Freshmeat. It is also possible to use driftnet to capture MPEG audio data from the network and play it through a player
such as mpg123(1).
Images may be saved by clicking on them.
OPTIONS -h Print a summary of usage.
-v Print additional details of packets captured to the terminal.
-b Beep when a new image is displayed.
-i interface
Listen to packets on interface. By default, driftnet will try to pick up traffic on all interfaces, but this does not work with all
versions of pcap(3); on such systems, an interface must be specified. On some systems, driftnet can only use promiscuous mode if an
interface is specified.
-f file
Instead of listening on an interface, read captured packets from a pcap(3); dump file; file can be a named pipe for use with Kismet
or similar.
-p Do not put the interface into promiscuous mode.
-a Operate in `adjunct mode', where driftnet gathers images for use by another program, such as Jamie Zawinski's webcollage. In this
mode, no window is displayed; images are captured and saved in a temporary directory, and their names written on standard output.
-m number
In adjunct mode, silently drop images if there are more than number in the temporary directory. It is assumed that another process
will delete images which it has processed.
-x prefix
The filename prefix to use when saving images, by default `driftnet-'.
-d directory
Use directory to store temporary files. Driftnet will clear this directory of its own temporary files on exit, but will not delete
the directory or any other files.
-s Attempt to capture streamed audio data from the network, and either play it or, in adjunct mode, save it in files. At present this
only works with MPEG data.
-S Capture streamed audio data only, ignoring images.
-M command
Use the named command to play MPEG audio data. The command, which is executed using the shell, should accept MPEG frames on standard
input. The default is `mpg123 -'.
filter code
Additional filter code to restrict the packets captured, in the libpcap syntax. User filter code is evaluated as `tcp and (filter
code)'.
