I am totally incapable of understanding this code snippet. Before comma I can see splitting, substring but , ++CNT[TMP]
May you please help?

shtool-fixperm

SHTOOL-FIXPERM.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-FIXPERM.TMP(1)

NAME

       shtool-fixperm - GNU shtool file permission fixing command

SYNOPSIS

       shtool fixperm [-v|--verbose] [-t|--trace] path [path ...]

DESCRIPTION

       shtool fixperm fixes file permissions inside a source tree under path by cleaning up the permission bits. It determines the cleaned up
       permission from the already set bits. It is intended to be run before a tarball is rolled (usually with shtool tarball) out of a source
       tree. The trick is that this is more convenient than having to set the permissions manually or by using a large file list.

OPTIONS

       The following command line options are available.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

EXAMPLE

	#   Makefile.in
	dist:
	    shtool fixperm -v *
	    ...

HISTORY

       The GNU shtool fixperm command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1996 for OSSP eperl.  It was later
       taken over into GNU shtool.

SEE ALSO

       shtool(1), chmod(1).
