Homework and Emergencies Homework & Coursework Questions Help with shell scrip syntax errors Post 302983703 by RudiC on Saturday 15th of October 2016 09:01:38 AM

Hello Demas, welcome to unix.com!

In your school data the course number is missing. Please complete.

Please be aware that supplying sample data like channels.txt and registrations.txt usually helps, as does posting the syntax error messages.
On first sight, I see the following:
- missing double semicolons on a few of the cases.
- << opens a "here document", the syntax (and logics) for which you do not follow. It seems you would need an output redirection in those places.
- grep et al. don't need cat - they usually read the input files by themselves.

NAME

       afInitSampleFormat, afInitByteOrder, afInitChannels, afInitRate - initialize audio data format for a track in an audio file setup

SYNOPSIS

       #include <audiofile.h>

       void afInitSampleFormat(AFfilesetup setup, int track, int sampleFormat,
	   int sampleWidth);
       void afInitByteOrder(AFfilesetup setup, int track, int byteOrder);
       void afInitChannels(AFfilesetup setup, int track, int channels);
       void afInitRate(AFfilesetup setup, int track, double rate);

PARAMETERS

       setup is a valid file setup returned by afNewFileSetup(3).

       track specifies a track within the audio file setup. track is always AF_DEFAULT_TRACK for all currently supported file formats.

       sampleFormat is a symbolic constant specifying the sample format for the audio data in the track. sampleFormat must be one of
       AF_SAMPFMT_TWOSCOMP, AF_SAMPFMT_UNSIGNED, AF_SAMPFMT_FLOAT, or AF_SAMPFMT_DOUBLE.

       sampleWidth is a positive integer specifying the number of bits for each sample in the track.

       byteOrder is a symbolic constant specifying the byte order of the track. byteOrder must be one of AF_BYTEORDER_BIGENDIAN or
       AF_BYTEORDER_LITTLEENDIAN.

       channels is a positive integer specifying the number of channels in the track.

       rate is a positive double-precision floating-point number specifying the sample rate of the track.

DESCRIPTION

       afInitSampleFormat initializes the track to the specified sample format and sample width.

       afInitByteOrder initializes the track to the specified byte order.

       afInitChannels initializes the track to the specified number of channels.

       afInitRate initializes the track to the specified sample rate.

ERRORS

       afInitSampleFormat, afInitByteOrder, afInitChannels, and afInitRate can produce the following errors:

       AF_BAD_FILESETUP   setup represents an invalid file setup.

       AF_BAD_TRACK	  track represents an invalid track identifier.
