Each of the files consisted of 7 columns: the first three columns are the same in each file and the other 4 columns are the actual data (but we need to use only the last three of those). The merging would mean to keep the first three columns and then add the the last three columns of each file matched by the first column. For example, infile1 could be

Code:
a b c 1 2 3 4
d e f 5 6 7 8
g h j 9 10 11 12

infile2 could be:

Code:
a b c 11 3 4 5 
g h j 9 8 7 6
d e f 1 2 3 4

infile3 could be

Code:
d e f 2 3 4 5
a b c 5 6 7 8
g h j 9 10 11 12



then the after the merging step1, the outfile1 would look like like this:

Code:
a b c 1 2 3 4 3 4 5
d e f 5 6 7 8 2 3 4
g h j 9 10 11 12 8 7 6

then after adding infile3, the outfile2 would look like this:

Code:
a b c 1 2 3 4 3 4 5 6 7 8
d e f 5 6 7 8 2 3 4 3 4 5
g h j 9 10 11 12 8 7 6 10 11 12

I hope this clears things up.

Many thanks!

makecsd

MAKECSD(1)						  The Canonical Csound Reference						MAKECSD(1)

NAME

       makecsd - Creates a CSD file from the specified input files. .

DESCRIPTION

       Creates a CSD file from the specified input files. The first input file that has a .orc extension (case is not significant) is put to the
       <CsInstruments> section, and the first input file that has a .sco extension becomes <CsScore>. Any remaining files are Base64 encoded and
       added as <CsFileB> tags. An empty <CsOptions> section is always added.

       Some text filtering is performed on the orchestra and score file:

       o   newlines are converted to the native format of the system on which makecsd is being run.

       o   blank lines are removed from the beginning and end of files.

       o   any trailing whitespace is removed from the end of lines.

       o   optionally, tabs can be expanded to spaces with an user specified tabstop size.

SYNTAX

	   makecsd [OPTIONS ... ] infile1 [ infile2 [ ... ]]

INITIALIZATION

       Flags:

       o   - t n = expand tabs to spaces using tabstop size n (default: disabled). This applies only to the orchestra and score file.

       o   - w n = set Base64 line width to n (default: 72). Note: the orchestra and score are not wrapped.

       o   - o fname = output file name (default: stdout)

EXAMPLES

	       makecsd -t 6 -w 78 -o file.csd file.mid file.orc file.sco sample.aif

       This creates a CSD from file.orc and file.sco (tabs are expanded to spaces assuming a tabstop size of 6 characters), and file.mid and
       sample.aif are added as <CsFileB> tags containing Base64 encoded data with a line width of 78 characters. The output file is file.csd.
