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

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.

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 empty lines in place with backup

-r : repeat mode

Print line immediately before a matching regex.

Use this if you don't have access to GNU grep's -B option.

The Hidden PS

While going through the source code for the well known ps command, I read about some interesting things.. Namely, that there are a bunch of different fields that ps can try and enumerate for you. These are fields I was not able to find in the man pages, documentation, only in the source. Here is a longer function that goes through each of the formats recognized by the ps on your machine, executes it, and then prompts you whether you would like to add it or not. Adding it simply adds it to an array that is then printed when you ctrl-c or at the end of the function run. This lets you save your favorite ones and then see the command to put in your .bash_profile like mine at : http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Note that I had to do the exec method below in order to pause with read. t () { local r l a P f=/tmp/ps c='command ps wwo pid:6,user:8,vsize:8,comm:20' IFS=' '; trap 'exec 66

Stream and copy a video from lan

Requires a listening port on HOST eg. "cat movie.mp4 | nc -l 1356 " (cat movie.mp4 | nc -l PORT) Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth. You can't seek (it'll crash and kill the stream) but you can pause it.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Recursive grep of all c++ source under the current directory

I like this better than some of the alternatives using -exec, because if I want to change the string, it's right there at the end of the command line. That means less editing effort and more time to drink coffee.

Convert deb to rpm

converts between Red Hat rpm, Debian deb, Stampede slp, Slackware tgz, and Solaris pkg file formats ... It also supports LSB packages.

Create arbitrary big file full of zeroes but done in a second

If you want to create fast a very big file for testing purposes and you do not care about its content, then you can use this command to create a file of arbitrary size within less than a second. Content of file will be all zero bytes. The trick is that the content is just not written to the disk, instead the space for it is somehow reserved on operating system level and file system level. It would be filled when first accessed/written (not sure about the mechanism that lies below, but it makes the file creation super fast). Instead of '1G' as in the example, you could use other modifiers like 200K for kilobytes (1024 bytes), 500M for megabytes (1024 * 1024 bytes), 20G for Gigabytes (1024*1024*1024 bytes), 30T for Terabytes (1024^4 bytes). Also P for Penta, etc... Command tested under Linux.
