Top Forums Shell Programming and Scripting The Start Of A Simple Audio Scope Shell Script... Post 302781419 by wisecracker on Saturday 16th of March 2013 01:11:23 PM

Well this script code is now taking shape...

Apologies for any typos...

It has some _command_line_ stuff to alter certain parameters and a few status line updates.

The _commands_ are not case sensitive and there is a starter help window built in also.

HELP and some other commands will auto switch from capture mode to rerun mode displaying the last capture taken. READ THE CODE for more information...

There is a commented out section that would, if edited according to the instructions in the code, generate another shell script and run it in a separate terminal. This will generate an 8 second burst of 1KHz sinewave and as long as the window is the active one just press ENTER to keep rerunning or Ctrl-C to quit the script and close down the terminal...

Connecting the output of the signal to the mic input and adjusting the audio system's gain controls will display a nice sinewave within the limits of standard text mode...

If you edit and run the generator script then SOX must be installed...

I hope this will become a practical kids learning tool along with some simple HW construction in the not too distant future...

As you will see almost EVERYTHING that is needed for testing, calibration running and the like will be generated from this one script only...

Enjoy...

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
