simple nbtstat -a equivalent/alias for linux (uses nmblookup)

it's a mixed environment where I work, and since we still use WINS services, this is often a quick and dirty way for me to obtain a mac-address for a hostname. please note that nmblookup is part of the samba suite. Just another one of those nearly useless commands that is super cool when and only when you need it. Show Sample Output

```
$ nbtstat bradyr
querying bradyr on x.x.x.x
y.y.y.y bradyr<00>
Looking up status of y.y.y.y

Makes you look busy

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) ) This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.
This is sample output - yours may be different.
0

alias busy='rnd_file=$(find /usr/include -type f -size +5k | sort -R | head -n 1) && vim +$((RANDOM%$(wc -l $rnd_file | cut -f1 -d" "))) $rnd_file'

Clear scrollback on all participating terminals.

Syntax outside of an alias would be printf %b \\033c. This clears the screen and removes scrollback. Works on gnome-terminal and the XFCE's Terminal, and XTerm. It does clear the screen in Konsole and the Mac Terminal, but does not clear scrollback.

Play flash video in the cache (loaded) with mplayer

Alias to play flash videos with mplayer. You can replace mplayer with your favorite video player. This alias supports Chrome & Firefox's way of handling the flash plugin. It will play all the videos in the cache. Note that certain videos might never make it to the cache, if the publisher ask for them not to: they will just be loaded in RAM. A variant if you're just interested in playing the audio, for example for a music : alias flashmusic="mplayer -vo null \$(find /proc/\$(pgrep -f 'libgcfl|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"

private mode for (bash) shell

same as "unset HISTFILE" - but the advantage is that you can "tab-complete" it and when you do, you won't mistype it (which could lead to not unsetting the HISTFILE). put the alias in the ~/.bash_profile or ~/.bashrc file in your users home directory, respawn, enjoy! :) Show Sample Output

Remove ( color / special / escape / ANSI ) codes, from text, with sed

Remove ( color / special / escape / ANSI ) codes, from text, with sed Credit to the original folks who I've copied this command from. The diff here is: Theirs: [m|K] Theirs is supposed to remove \E[NUMBERS;NUMBERS[m OR K] This statement is incorrect in 2 ways. 1. The letters m and K are two of more than 20+ possible letters that can end these sequences. 2. Inside []'s , OR is already assumed, so they are also looking for sequences ending with | which is not correct. This : [a-zA-Z] This resolves the "OR" issue noted above, and takes care of all sequences, as they all end with a lower or upper cased letter. This ensures 100% of any escape code 'mess' is removed.
