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.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Recursive chmod all *.sh files within the current directory

This command is useful to recursively make executable all "*.sh" files in a folder. This command is useful to apply chmod recursively in a determined kind of file.

Get a list of the top 10 heaviest tables in your mysql database - useful for performance diagnostics

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

Short URL to commandlinefu.com commands

Obviously replace the relevant parts as required. The following also work: $ lynx cmdl.in/efu/by-marcel -or- $ lynx cmdl.in/efu/view-9058

this toggles mute on the Master channel of an alsa soundcard

Execute MySQL query send results from stdout to CSV

You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Download latest NVIDIA Geforce x64 Windows driver

Download latest NVIDIA Geforce x64 Windows7-8 driver from Nvidia's website. Pulls the latest download version (which includes beta). This is the "English" version. The following command includes a 'sed' line to replace "english" with "international" if needed. You can also replace the starting subdomain with "eu." "uk." and others. Enjoy this one liner! 1 character under the max :) $wget "us.download.nvidia.com$(wget -qO- "$(wget -qO- "nvidia.com/Download/processFind.aspx?psid=95&pfid=695&osid=19&lid=1&lang=en-us" | awk '/driverResults.aspx/ {print $4}' | cut -d "'" -f2 | head -n 1)" | awk '/url=/ {print $2}' | sed -e "s/english/international/" | cut -d '=' -f3 | cut -d '&' -f1)"

Interactively build regular expressions

txt2regex can be interactive or noninteractive and generates regular expressions for a variety of dialects based on user input. In interactive mode, the regex string builds as you select menu options. The sample output here is from noninteractive mode, try running it standalone and see for yourself. It's written in bash and is available as the 'txt2regex' package at least under debian/ubuntu.
