Hello!
Im trying to read file contents. Then, print out every line that has "/bens/here" in the file that was read.
cat /my/file.now | sed '/bens/here/p'
I keep getting the error asking if I need to predeclare sed?
What does predeclaring sed mean?
Thanks!

Hi guys.
I need a sed command to print like 10 lines after a regular expression is found in the log.
Can anyone help me out.
Thanks

Hi all,
This should be very easy but I can't figure it out...
I have a file that looks like this:

I have a very large results file, and a list of filters
grep -wf filterlist.txt datafile.txt > outfile.txt
The above line works but is very slow and I'm wondering how to make it faster.
The items in my filterlist are only relevant to the first column. I don't care if any item in the... (1 Reply)
I am trying to print those line which has no # in the begining of the line.
The sed I used for this purpose as shown below is not giving the required output.
echo 'PDE 5600' | sed -n 's/^\!#/&/p'
Where lies the problem:confused: (3 Replies)
HI All,
I am using grep command to serach a pattern in a list of files and storing the output in a variable. Then i am applying some logic on that variable to get the required output.
But Thing is that when the pattern is present mutiple times in a file, i am getting the output of grep in a... (3 Replies)
I am trying to extract a table of data (mysql query output) from a log file. I need to print everything below the header and not past the end of the table. I have spent many hours searching with little progress. I am matching the regexp +-\{99\} with no problem. I just can't figure out how to print... (5 Replies)

get-oui
GET-OUI(1) General Commands Manual GET-OUI(1)NAME
get-oui - Fetch the arp-scan OUI file from the IEEE website
SYNOPSIS
get-oui [options]
DESCRIPTION
get-oui fetches the Ethernet OUI file from the IEEE website, and saves it in the format used by arp-scan.
The OUI file contains all of the OUIs (Organizationally Unique Identifiers) that have been registered with IEEE. Each OUI entry in the
file specifies the first 24-bits of the 48-bit Ethernet hardware address, leaving the remaining 24-bits for use by the registering organi-
sation. For example the OUI entry "080020", registered to Sun Microsystems, applies to any Ethernet hardware address from
08:00:20:00:00:00 to 08:00:20:ff:ff:ff inclusive. Each OUI assignment represents a total of 2^24 (16,777,216) Ethernet addresses.
Every major Ethernet hardware vendor registers an OUI for their equipment, and larger vendors will need to register more than one. For
example, 3Com have a total of 37 OUI entries. Organisations that only produce a small number of Ethernet devices will often obtain an IAB
registration instead. See get-iab(1) for details.
This script can be used to update the arp-scan OUI file from the latest data on the IEEE website. Most of the Ethernet addresses in use
belong to an OUI registration, so this is the most important of the files that arp-scan uses to decode Ethernet hardware addresses. You
should therefore run get-oui occasionally to keep the arp-scan OUI file up to date.
The OUI data is fetched from the URL http://standards.ieee.org/regauth/oui/oui.txt and the output file is saved to the file ieee-oui.txt in
the current directory. The URL to fetch the data from can be changed with the -u option, and the output file name can be changed with the
-f option.
The ieee-oui.txt file that is produced by this script is used by arp-scan to determine the Ethernet card vendor from its hardware address.
The directory that arp-scan will look for the ieee-oui.txt file depends on the options used when it was built. If it was built using the
default options, then it will look in /usr/local/share/arp-scan.
OPTIONS -h Display a brief usage message and exit.
-f <fn>
Write the output to the specified file instead of the default ieee-oui.txt.
-u <URL>
Use the specified URL to fetch the raw OUI data from instead of the default http://standards.ieee.org/regauth/oui/oui.txt.
-v Display verbose progress messages.
FILES
ieee-oui.txt
The default output file.
EXAMPLES
$ get-oui -v

NOTES
get-oui is implemented in Perl, so you need to have the Perl interpreter installed on your system to use it.
get-oui uses the LWP::Simple Perl module to fetch the data from the IEEE website. You must have this module installed on your system for it
to work. This module is available on most distributions, often called libwww-perl. It is also available in source form from CPAN.
You can use a proxy server by defining the http_proxy environment variable.
