<p style="color: grey"> Bash recipe 580801 by <a href="/recipes/users/4177147/">Barry Walker</a> (<a href="/recipes/tags/alarm/">alarm</a>, <a href="/recipes/tags/apple/">apple</a>, <a href="/recipes/tags/audio/">audio</a>, <a href="/recipes/tags/baby_alarm/">baby_alarm</a>, <a href="/recipes/tags/cygwin/">cygwin</a>, <a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/noise/">noise</a>, <a href="/recipes/tags/sleep/">sleep</a>, <a href="/recipes/tags/sound/">sound</a>, <a href="/recipes/tags/whitenoise/">whitenoise</a>). </p> <p>This is a simple BASH, DASH and SH script to sooth a newborn baby to sleep for a laptop with a builtin mic. Develeoped around an Apple MacBook Pro.</p> <p>Usage:- [./]shush.sh &lt;time in seconds from 18 to 2700&gt; [sensitivity [Hh|Mm|Ll]]&lt;CR&gt;</p> <p>If time is omitted it defaults to 2 bursts of 9 seconds each and if sensitivity is omitted defaults to [M]edium.</p> <p>It uses Quicktime Player for Apple OSX 10.12.4 minimum /dev/dsp for CygWin and some Linux flavours and arecored for Linux ALSA machines for baby awake detector.</p> <p>Upon the two arguments the white noise generator runs for approximately the time given in $1 in bursts of 9 seconds until the time limit is reached. $2 is used to detect of baby is awake and reruns the noise generator again with a new noise waveform.</p> <p>Enjoy...</p>

This is a little tongue-in-cheek but an enjoyable bit of fun.</p> <p>It took around 11 seconds to prove 90000000000 had a perfect square of 300000...</p> <p>It is a stand alone program and has a degree of INPUT error correction...</p> <p>It was done on a MacBook Pro, OSX 10.7.5, default bash terminal and should work on Linux flavours but it is untested...</p> <p>Enjoy finding simple solutions to often very difficult problems...</p> <p>Bazza...</p>

Revision 2. </p> <p>This bash script is a taster for a kids level, audio, text mode, sweep generator. The code just creates a single cycle of a quantised sine curve inside an 80 x 24 bash terminal. This will be the calculator for a sinewave sweep generator from about 50Hz the 12KHz... The code tells you more and the display is in comments at the end...</p>

Next the Python terminal window is written to for the 5 seconds of delay; see code. And finally the Title Bar is restored to normal...</p> <p>A snapshot image can be seen here:-</p> <p><a href="http://wisecracker.host22.com/public/Title_Bar.jpg" rel="nofollow">http://wisecracker.host22.com/public/Title_Bar.jpg</a></p> <p>Bazza...</p>
