You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds.

Someone better at awk could probably reduce this down a lot.

Output is from Debian Lenny

This is how I typically grep. -R recurse into subdirectories, -n show line numbers of matches, -i ignore case, -s suppress "doesn't exist" and "can't read" messages, -I ignore binary files (technically, process them as having no matches, important for showing inverted results with -v)

I have grep aliased to "grep --color=auto" as well, but that's a matter of formatting not function.

Searches all files,dirs (also hidden) recursively

shorter typing with no need to use xargs.

List all text files in the current directory.

After executing this, click on a window you want to track X Window events in.

Explaination: "xev will track events in the window with the following -id, which we get by greping window information obtained by xwininfo"

Show apps that use internet connection at the moment.

Can be used to discover what programms create internet traffic. Skip the part after awk to get more details, though it will not work showing only unique processes.

This version will work with other languages such as Spanish and Portuguese, if the word for "ESTABLISHED" still contain the fragment "STAB"(e.g. "ESTABELECIDO")

This corrects duplicate output from the previous command.

Has anyone an idea why the uniq doesn't work propperly here (see sample output)?

This is just for fun.

This obey that you don't match any broadcast or network addresses and stay between 1.1.1.1 - 254.254.254.254

regex to match an ip

Not as far off as you thought, now is it?

Define a function

Use it to print some column headers

This helped me find a botnet that had made into my system. Of course, this is not a foolproof or guarantied way to find all of them or even most of them. But it helped me find it.

OS: Debian based (or those that use dpkg)

Equivalent to doing a dpkg -S on each file in $PATH, but way faster.

May report files generated though postinstall scripts and such. For example . It will report /usr/bin/vim .. which is not not a file installed directly by dpkg, but a link generated by alternatives hooks

Connect to a machine running ssh using mac address by using the "arp" command

alias ps?='psg' for maximum hawtness. Works in bash or zsh.

If you still connect to your wireless access point manually and need to use wpa_supplicant, the above fu will grep all of the known SSID from your wpa_supplicant.conf file, present it in a Zenity list and return the SSID name you choose. I've wrapped this command in to a bash script that then up's the interface, associates and autenticates. Saves me from using NetworkManager ;)

Make sure that find does not touch anything other than regular files, and handles non-standard characters in filenames while passing to xargs.
