Check These Out
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials
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
Play files in shuffle mode with bash and mpg123.
Why bother using big-as-hell stuff like mplayer? This will play all your music files contained in */* (in my case author/song.format) with bash and mplayer showing a nice output.
need package: pv
apt-get install pv
get the iso size in byte with
ls -l install-cd.iso
/dev/sdb is your USB Device (without partitionNr.)
#4345 also works under windows
create the function then run 'yt-chanrip username' to download that user's entire channel.
uses youtube-dl and the GData API. similar to http://www.commandlinefu.com/commands/view/3154/download-youtube-playlist
On the Mac, the format ifconfig puts out is little different from Linux: the IP address is space separated, instead of colon. That makes parsing the IP address easier. See releated command for Linux/Unix:

Runs an instance of screen with name of "name_me" and command of "echo "hi""
To reconnect to screen instance later use:

Create a encrypted tar.gz file from a directory on the fly. The encryption is done by GPG with a public key. The resulting filename is tagged with the date of creation. Very usefull for encrypted snapshots of folders.
