Check These Out

find all active IP addresses in a network
I just added the args [arp-scan --localnet] which works for Debian users, because the package 'arp' has name 'arp-scan', and it doesn't works with the argument 'arp'.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Analyse an Apache access log for the most common IP addresses
This uses awk to grab the IP address from each request and then sorts and summarises the top 10.

Find all files containing a word
This command will find all files recursively containing the phrase entered, represented here by "searchphrase". This particular command searches in all php files, but you could change that to just be html files or just log files etc.

Create a backup of the file.
It will create a backup of the filename. The advantage is that if you list the folder the backups will be sorted by date. The command works on any unix in bash.

List only executables installed by a debian package
Maybe not clean with big package and too long argument. But return every file who can be executed.

Quick key/value display within /proc or /sys
Within /proc and /sys there are a lot of subdirectories, which carry pseudofiles with only one value as content. Instead of cat-ing all single files (which takes quite a time) or do a "cat *" (which makes it hard to find the filename/content relation), just grep recursively for . or use "grep . /blabla/*" (star instead of -r flag). For better readability you might also want to pipe the output to "column -t -s : ".

Collect a lot of icons from /usr/share/icons (may overwrite some, and complain a bit)
Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.

Convert wmv into avi

Simple way to envoke a secure vnc session through ssh enabled router.
The ip address is of the remote machine running the vncserver. Must log in first to the router then the VNC session. Very nice if you have open-wrt or dd-wrt on your router.
