In trying to find the Korn version, I tried these 2 ways found in another thread. Both didn't give me an answer.
>print ${.sh.version}
ksh: ${.sh.version}: 0403-011 The specified substitution is not valid for this command.
>what /bin/ksh | grep Version
>

At logon time I get this as the possible O/S version ?
* Operating system ..: AIX (64Bit)
* Version / release .: 5.2

Accessing the manual on anything is not helpfull as nothing seams to be defined in 'man'.
>man ksh
Manual entry for ksh not found or not installed.
>man ls
Manual entry for ls not found or not installed.
>man ps
Manual entry for ps not found or not installed.
>man cd
Manual entry for cd not found or not installed.
>man
Usage: man [[[-ct] [section]] | [-f | -k]] [-M path] [-r] name...


If I do like you said, I get an error :

>. MyAlias.sh
ksh: MyAlias.sh: not found


I found another script who's first line is '#/bin/ksh' and not '#!/bin/ksh' but using either method simply doesn't work with my script :
>./MyAlias.sh
>ll
ksh: ll: not found
>. MyAlias.sh
ksh: MyAlias.sh: not found

That other script I mentioned actualy works as I ran it last week. Could it be that the problem is isolated to the ALIAS command in scripts ?


In finding other shells I have access to :
>ls /bin/*sh*
...
/bin/bsh
/bin/chsh
/bin/csh
/bin/ksh
/bin/ksh93
...

in /etc/passwd, my ID is there with '/usr/bin/ksh' at the end. So I assume, at logon, I fall into Korn shell ?


Assuming the problem is isolated to ALIAS commands in a shell script, I modified my script to :
#!/bin/ksh
#set -x

echo "before alias"
alias goto_ae='cd /usr/local/Tivoli/custom/policy'
alias ll='ls -al'
echo "after alias"

>./MyAlias.sh
before alias
after alias


I executed it and got the echo printouts. So there is a problem with the ALIAS but why ?

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.
