Convert a VMWare screencast into a flv file

First, we convert the VMware avi (VMnc format) to the Microsoft avi format. Next, we convert the Microsoft avi format to FLV format. You can play around with the -r switch (rate per second) and the -b switch (bitrate). But, if those get larger, so does your FLV file.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

list with full path

Extract title from HTML files

previous version leaves lots of blank lines

Quick plotting of a function

The arguments of "seq" indicate the starting value, step size, and the end value of the x-range. "awk" outputs (x, f(x)) pairs and pipes them to "graph", which is part of the "plotutils" package.

Safe Delete

remove file that has sensitive info safely. Overwrites it 33 times with zeros

Show apps that use internet connection at the moment. (Multi-Language)

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")

Top 30 History

Top 30 History Command line with histogram display

continuously print string as if being entered from the keyboard

Cycles continuously through a string printing each character with a random delay less than 1 second. First parameter is min, 2nd is max. Example: 1 3 means sleep random .1 to .3. Experiment with different values. The 3rd parameter is the string. The sleep will help with battery life/power consumption. $ cycle 1 3 $(openssl rand 100 | xxd -p) Fans of "The Shining" might get a kick out of this: $ cycle 1 4 ' All work and no play makes Jack a dull boy.'

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Text graphing ping output filter

Nasty perl one-liner that provides a sparkline of ping times. If you want a different history than the last 30, just put that value in. It (ab)uses unicode to draw the bars, inspired by https://github.com/joemiller/spark-ping . It's not the most bug-free piece of code, but what it lacks in robustness it makes up for in capability. :) If anyone has any ideas on how to make it more compact or better, I'd love to hear them. I included a ping to google in the command just as an example (and burned up 10 chars doing it!). You should use it with: $ ping example.com | $SPARKLINE_PING_COMMAND

Serial console to a Vmware VM

Create a serial console with "socket (named pipe)" of "/tmp/socket", "from:server, to:virtual machine" in vmware player, etc.. gui. Run the above command after you have booted the guest OS (which should also be configured for serial console).
