Generate a truly random password using noise from your microphone to seed the RNG. This will spit out 12 password with 12 characters each, but you can save this into a bash script and replace 'pwgen -ys 12 12' with 'pwgen $@' so you can pass any paramters to pwgen as you would normally do. Show Sample Output
1TMPFILE="/tmp/$RANDOM$RANDOM$RANDOM$RANDOM$RANDOM" && arecord -d 1 -t raw -f cd -q | base64 > $TMPFILE && pwgen -ys 12 12 -H $TMPFILE $@ && rm $TMPFILE -

This function is used to sort selected lines of a text file to the end of that file. Especially useful in cases where human intervention is necessary to sort out parts of a file. Let's say that you have a text file which contains the words rough slimy red fluff dough For whatever reason, you want to sort all words rhyming with 'tough' to the bottom of the file, and all words denoting colors to the top, while keeping the order of the rest of the file intact. '$EDITOR' will open, showing all of the lines in the given file, numbered with '0' padding. Adding a '~' to the beginning of the line will cause the line to sort to the end of the file, adding '!' will cause it to sort to the beginning. Show Sample Output
02end () ( export LC_ALL=C; nl -n rz $1 > $1.tmp; ${EDITOR:-vi} $1.tmp; sort $1.tmp | sed -r 's/^.*[0-9]+\t+//' > $1; rm $1.tmp; ) -
