Thanks. What i am trying to say is that data of 1st row in file 1 needs to be compared with data of 5th row.(this is just an example as data in the files are in different sort order)
In a nutshell, User should be prompt to provide the common key (means the user will be entering the column number.) Based on common key the data should be compared.
So considering the same example as above
File1
1|check|test|plan|672
4|checked|this|plan|610
3|just|no|plan|612
File2
1|chck|test|plan|670
3|jst|no|pln|400
4|checked|ok|plan|610
User will provide the common key (let's say the user has provided 1, it means first column in each file is the primary key to identify records)
Output should be in tabular form
Difference
Row ColumnNumber Value in File1 Value in File2
1 2 check chck
1 5 672 670
2 3 this ok
3 2 just jst
3 4 plan pln
3 5 612 400
*Row - Here row should row number of first file and also if possible we can display the primary key also
One more thing here is user can provide the combination of keys also.
Hope i have cleared my question now.

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