You're not bothering me! I just don't understand what you're trying to do.

Please show us a sample of the output produced by the command:

Code:

sha256sum file

with file replaced by the name of one of the files you are processing.

If you sort the output of sha256sum file on the field that contains the checksum it produces, then lines in the output with the same checksum would presumably be copies of each other.

But, if you have several files with the same name with different checksums, the checksum will not tell you anything at all about which file contains the longest recording nor about which file has the highest quality audio.

Please just explain how your code is supposed to determine which file you want to end up in your destination directory if more than one pathname in your source file hierarchy has the same final component.

The only thing in your current code that copies files into your destination directory is the simple command:

Code:

cp -nr /home/directory/origin /home/directory/destination

which will search the file hierarchy rooted in /home/directory/origin and copy every non-directory file it finds to /home/directory/destination that doesn't already exist in that directory. If there is more than one file in the source hierarchy with the same name, the first one encountered will be copied (if there isn't already a file in that directory with that name before the cp was invoked). The order in which cp searches the source hierarchy is unspecified.

Assuming that the destination directory exists at the time you invoke the above cp command, nothing in the commands you have shown us (except that cp command), has any affect on copying files nor on selecting which files will be copied to the destination directory.

mkcfm

MKCFM(1)						      General Commands Manual							  MKCFM(1)

NAME

       mkcfm - create summaries of font metric files in CID font directories

SYNOPSIS

       mkcfm [CID-font-directory-name]

DESCRIPTION

       There  is  usually only one CID font directory on the X font path. It is usually called /usr/X11R6/lib/X11/fonts/CID. If you do not specify
       an argument, mkcfm will try to go through the subdirectories of that directory, and create one summary of font metric files for	each  CID-
       Font (character descriptions) file and each CMap (Character Maps) file it finds. The summaries of font metric files are put in the existing
       CFM subdirectory. The CFM subdirectories are created when CID-keyed fonts are installed.

       If you specify a CID font directory as an argument, mkcfm will try to go through the subdirectories of that directory, and create one  sum-
       mary  of  font metric files for each CIDFont file and each CMap file it finds.  mkcfm will calculate the summaries of the font metric files
       stored in AFM subdirectories of the CID font directory.

       Those summaries are needed by the rasterizer of CID-keyed fonts to speed up the response to X font calls. If those files do not exist,  CID
       rasterizer  will  have  to go through usually large font metric files, and calculate the summaries itself each time the font is called. You
       will notice a substantial wait on a call to a large CID-keyed font.

FILES

       .afm files     Each CID-keyed font file is supposed to have a font metric file (.afm file). mkcfm creates summary  files  (.cfm	files)	of
		      those  font metric files. mkcfm should be run whenever a change is made to the files stored in the subdirectories of the CID
		      font directory. For example, it should be run when new CID fonts are installed.

       .cfm files     Summaries of font metric (.afm) files created by mkcfm.

SEE ALSO

       The rasterizer for CID-keyed fonts in the directory xc/lib/font/Type1.
