Top Forums Shell Programming and Scripting To make my script multi-os compatible Post 302843061 by wisecracker on Monday 12th of August 2013 03:10:51 AM

The code is not there so a few pointers...

1) Never make assumtions without quoting them and/or investigating them.
2) Do NOT take directory/folder/drawer trees as being identical on all the platforms.
3) Obtain units with default installs of the OSes you want to test with.
4) Check that the shell you want to use exists. Most Linux installs and the Macbook Pro default to bash.
5) Try to make your code backwards compatible - seriously difficult in Python.
6) If you are doing something odd inside the Terminal, (colours for example), ensure that the Terminals can handle them.
7) Ensure that any _commands_ you use exist and have the arguments you need; for example "stat -c ........" does not work on this Macbook Pro as the -c argument does not exist.
8) If you are not sure ask a Forum like this one to try out a command with the arguments you need on their platform of choice. There are people willing to help as it is a learning curve for them too.
9) Can't think of anything else at the moment. ;o)
10) Oh, and I am an amateur coder, I code to work first not work to code, but once working I will ask for help in speeding up any routines...

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.
