I think it's a fine idea to write the program to C++. Yes, a C++ program doing the same logic as a perl program will be faster. But I agree there may be a bottleneck in the perl program that could be fixed.

Normally, I do a short task using bash. But once it gets to a certain level of complexity, I move to C. It runs faster, but that's not the main point. It's so much easier to maintain a complex program in C than a complex program in a scripting language. The same logic applies to perl, which is kind of infamous for somehow leading to undecipherable code. On the other hand, there are large applications written in perl.

A C++ program would have to be rebuilt to move it to a
different machine architecture and might need to be rebuilt to move
it to a different operating system even if they both run on the same hardware.
For the most part, I disagree with this assertion. If there is a graphic front end, it is often tricky writing multi-platform code. But for processing a log file, the program should compile on any platform, assuming the programmer is competent.

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.
