This command uses nmap to perform reverse DNS lookups on a subnet. It produces a list of IP addresses with the corresponding PTR record for a given subnet. You can enter the subnet in CDIR notation (i.e. /24 for a Class C)). You could add "--dns-servers x.x.x.x" after the "-sL" if you need the lookups to be performed on a specific DNS server.

On some installations nmap needs sudo I believe. Also I hope awk is standard on most distros.

I find this format easier to read if your going through lots of files. This way you can open the file in any editor and easily review the file

grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)

'jot' does not come with most *nix distros, so we need to use seq to make it work. This version tested good on Fedora 11.

Debian: Mark all dependent packages as manually installed. So they are not automatically removed if you remove some meta package - like gnome-desktop-environment for example.

This is an extension of a previous command by satyavvd on 2009-07-23 12:04:02, but this one grabs the whole archive. Hard coded numbers in previous script capped number of commands that could be fetched. This one grabs them all regardless of how big the archive gets.

to download latest version of "util", maybe insert a sort if they wont be shown in right order.

curl lists all files on mirror, grep your util, tail -1 will gets the one lists on the bottom and get it with wget

This will allow you to watch as matches occur in real-time. To filter out only ACCEPT, DROP, LOG..etc, then run the following command: watch 'iptables -nvL | grep -v "0 0" && grep "ACCEPT"' The -v is used to do an inverted filter. ie. NOT "0 0"

You can tell GCC to automatically select optimization commands and produce optimized code for the local machine (the one compiling the code), but you can't normally see what switches have been selected and used unless you append a "-v" and pause compilation.

Character: "?" is the Byte Order Mark (BOM) of the Unicode Standard.

Specifically it is the hex bytes EF BB BF, which form the UTF-8 representation of the BOM,

misinterpreted as ISO 8859/1 text instead of UTF-8.
