Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

cat /dev/urandom|od -t x1|awk 'NR > line { pos=int(rand()*15)+2;printf("%s",$pos);line=NR+(rand()*1000);digits = digits+2 } digits == 64 { print("\n");exit }'

Use this the next time you need to come up with a reasonably random bitstring, like for a WPA/WPA2 PSK or something. Takes a continuous stream of bytes coming from /dev/urandom, runs it through od(1), picking a random field ($0 and $1 excluded) from a random line and then prints it.

echo -n "text" | od -A n -t x1 |sed 's/ /\\x/g'

If you're going to use od, here's how to suppress the labels at the beginning. Also, it doesn't output the \x, hence the sed command at the end. Remove it for space separated hex values instead

od -c <FILE> | grep --color '\\.'

For fancier and cleaner output, try the following snippet :

showendlines(){ while read i; do od --address-radix=n --width=$(wc -c <<< "$i") -c <<< "$i" | perl -pe 's/.\K\s{2,3}//g'; done < $1 | grep --color '\\.'; }

Now you can run that with :

showendlines <FILE>

Thanks to prince_jammys to "debug" my English ;)

n=$RANDOM$RANDOM$RANDOM; let "n %= 10000000000"; echo $n
echo $RANDOM$RANDOM$RANDOM |cut -c3-12
head -c4 /dev/urandom | od -N4 -tu4 | sed -ne '1s/.* //p'
(Command too long..See sample Output..)

curl doesn't provide url-encoding for 'GET' data, it have an option '--data-urlencode', but its only for 'POST' data. Thats why I need to write down this commandline. With 'perl', 'php' and 'python', this is one liner, but just I wrote it for fun. Works in Ubuntu, will work in all linux varients(I hope it will work in unix varients also).
