OK, trying to guess what you're after, and making some assumptions, how about
We assume a *number* file is always present, all files have a .txt suffix, and the order of entries being sorted by item is acceptable...

If $1 in file1 matches $2 in file2. Then the value in $2 of file2 is updated to $1"."$2 of file2. The awk seems to only match the two files but not update. Thank you :).

I am trying to match $1 in file1 with $2 in file2. If a match is found then $3 and $4 of file2 are copied to file1. Both files are tab-delimeted and I am getting a syntax error and would also like to update file1 in-place without creating a new file, but am not sure how. Thank you :).

In the bash below the unique headers of each vcf.gz are stored in a text file with the same name. That is if 16-0000-file.vcf.gz was used the header text file would be 16-0000-file_header.txt.
There can be multiple vcf.gz in a directory, usually 3, that I need to fix the header in each file before... (6 Replies)
I am trying to create a cronjob that will run on startup that will look at a list.txt file to see if there is a later version of a database using database.txt as the source. The matching lines are written to output.

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.
