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.

nmap -sP 10.0.0.0/8 | grep -v "Host" | tail -n +3 | tr '\n' ' ' | sed 's|Nmap|\nNmap|g' | grep "MAC Address" | cut -d " " -f5,8-15

In the field, I needed to script a process to scan a specific vendor devices in the network. With the help of nmap, I got all the devices of that particular vendor, and started a scripted netcat session to download configuration files from a tftp server.

This is the nmap loop (part of the script). You can however, add another pipe with grep to filter the vendor/manufacturer devices only. If want to check the whole script, check in http://pastebin.com/ju7h4Xf4

Problem: I wanted to backup user data individually, using and incremental method. In this example, all user data is located in "/mnt/storage/profiles", and about 25 folders inside, each with a username ( /mnt/storage/profiles/mike; /mnt/storage/profiles/lucy ...)

I need each individual folder backed up, not the whole "/mnt/storage/profiles". So, using find while excluding directories depth and creating two variables (tarfile=username & desdir=destination), tar will create a .tgz file for each folder, resulting in a "mike_2013-12-05.tgz" and "lucy_2013-12-05.tgz".

find /mnt/storage/profiles/ -maxdepth 1 -mindepth 1 -type d | while read d; do tarfile=`echo "$d" | cut -d "/" -f5`; destdir="/local/backupdir/"; tar -czf $destdir/"$tarfile"_full.tgz -P $d; done

Renames files eliminating suffix, in this case everything after "-" is cutted. Just change "-" with the character you need.

Clears the "arp" table, without entering manually addresses (tested in Ubuntu).
