Shell Script Dependency/Tracer
Hello All,

We have a very old system at hand in which there are hundreds of shell scripts that use other shell scripts, all on the same server. There are several that are not used at all as well. In short, it's an unmanaged system thats been lying around for many years, and it needs to be cleaned up.

One of the ways I've been thinking of is to build a script that shows the plan of execution, given a seed script. For example, if a script A calls B and C and B calls M and N, then the given a seed of A, the script produces something like:

A
++B
++++M
++++N
++C

The intent of course is to identify which scripts are in use, and which ones are not.

Alternatively, I have considered checking the access timestamp using the -a option of ls to identify the script not being used for a long time. However, it does not give me the results I need.

Of course, I welcome other solutions to this problem and your experience if you've faced similar situations.

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.

KEYWORDS

       operating system, cpu architecture, platform, architecture
