  • Command makes use of the Malware Hash Registry ( It parses the current directory and subdirectories and calculates the md5 hash of the files, then prints the name and sends the hash to the MHR for a lookup in their database. The 3rd value in the result is the detection percentage across a mix of AV packages. Show Sample Output

    IFS=$'\n' && for f in `find . -type f -exec md5sum "{}" \;`; do echo $f | sed -r 's/^[^ ]+/Checking:/'; echo $f | cut -f1 -d' ' | netcat 43 ; done

  • Test whether real-time virus detection is working by running this command and checking for in /tmp. Requires real-time scanning to be enabled and active on the /tmp directory. If scanning is active, the file should be quarantined/deleted (depending on your settings) moments after running this command. If not, the (harmless) test file should remain in your /tmp directory.

  • If this matches any files on your web server expect to find allot of malware spread throughout your server folders. Seems to target wordpress sites. Be sure to check your themes/theme-name/header.php files manually for various redirect scripting usually in the line right above the close head tag. Good luck! Show Sample Output

    find / -name \*.php -exec grep -Hn .1.=.......0.=.......3.=.......2.=.......5.= {} \;

Find the package that installed a command

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Mac OS-X-> copy and paste things to and from the clipboard from the shell
Copies whatever is piped to the pbcopy command to the clipboard. pbpaste ... well pastes whats on the clipboard.

Find common groups between two users

Create a script of the last executed command
Sometimes commands are long, but useful, so it's helpful to be able to make them permanent without having to retype them. An alternative could use the history command, and a cut/sed line that works on your platform. $history -1 | cut -c 7- >

Awk: Perform a rolling average on a column of data
Sometimes jittery data hides trends, performing a rolling average can give a clearer view.

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Partition a sequence of disk drives for LVM with fdisk
So, I'm using a CentOS VM in VirtualBox, and created four new disks in the SCSI controller. The VM created the folders: /dev/sda /dev/sdb /dev/sdc /dev/sdd Using a 'for loop' all disks are partitioned for LVM.

check open ports without netstat or lsof

Scan Subnet for IP and MAC addresses
