An EXTREMELY powerful fork bomb. You have been warned.

A normal fork bomb looks something like this: _(){ _|_& };_ If you really felt like it, you could even create a devastating little script like this: #!/bin/bash _(){ _|_&&_& };_;:(){ :|:&&:& };:;.(){ .|.&&.& };. Please, for the love of resources, do not run this on a company, school, public, etc machine. Show Sample Output

Throttling Bandwidth On A Mac

sudo ipfw pipe 1 config bw 50KByte/s Set the bandwidth (bw) limit to any number you want. For example you could have a 15kb pipe for X application and then a 100kb pipe for another application and attach things to those pipes. If a port isn’t attached to a pipe, it runs at full speed. Change the number (in this case 1) to a different number for a different pipe. The next step is to attach your port. sudo ipfw add 1 pipe 1 src-port 80 In this case anything on port 80 (http) will be set to a limit of 50Kbyte/s. If you want to attach a second port to this pipe, repeat the command but change the port number at the end. src : http://www.mactricksandtips.com/2008/12/throttling-bandwidth-on-a-mac.html

List only hidden files

You can omit the -d to see what's inside directories. In that case, you may want -a to see dotfiles inside those directories. (Otherwise you don't need -a since you're explicitly looking at them.)

Get size of terminal

Exclude svn directories with grep

fix flash video (flv) file (ffmpeg)

Rebuild flv files that are broken (can't seek). This method probably works for other video/audio formats that can become broken in the same way.

Encode/Decode text to/from Base64 on a Mac w/out Mac Ports

I have a mac, and do not want to install mac ports to get the base64 binary. Using openssl will do the trick just fine. Note, to decode base64, specify a '-d' after 'base64' in the command. Note also the files base64.decoded.txt and base64.encoded.txt are text files.
