Question about Shell Programming
Post 18049 by rwb1959 on Friday 22nd of March 2002 02:28:09 PM

It has been my experience, that true "shell programming"
is in fact "programming". I have seen, used and even written
some very complex and highly functional shell programs.
There are some however that do feel this is NOT "real"
programming. I would venture to say that these folks
either have never written anything in a "shell language"
or have simply just "dabled" in small scripts from time to time.
So I guess it's all a matter of opinion and degree
As far as cleanup goes, most often this refers to the use
of temporary files and such when writing shell programs.
In which case, you should "clean up" after using them meaning,
remove them. In the case of other programming languages it
may also apply to closing network and/or DB connections and
such.

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 platform::shell 1.1.4 platform::shell(n)
