Thank you for sharing this script. It is an interesting approach to the problem.

Personally I would avoid letting the Shell see the funny filenames by avoiding the use of Shell Environment Variables and using temporary files instead. Similarly if I really need to use "sed" (not "tr") then I'd compose the "sed" commands in a "sed" file where Shell can't see them.

I have a local problem with commercial software which can create files with any name - including screen control escape sequences and absolutely anything a user can type on a keyboard.
The script to deal with this rationalises the filename before any "old files" cleanup sees the file. It also "corrects" any filenames starting with a hyphen character (for obvious reasons) and deletes any file consisting totally of garbage characters and/or space characters.
The reasoning behind the script is to stop the "old files" cleanup failing or executing dubious "rm" statements by renaming or removing files with dodgy names before running the cleanup.

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
