Re: Really strange behaviour or even a bug in MKSH

[Carsten Peter]

It's getting even stranger ...

First, I definitly use MKSH as there's no other KSH version installed.

I modified my example script as follows:
------------------------------------------------------------
#! /bin/ksh

echo "******************************"
echo "${KSH_VERSION}"
echo "${.sh.version}"
echo "******************************"

. ./include.src

./exitcode1.sh

exit 0
------------------------------------------------------------

After executing that my terminal session still works fine (I typed 'lsx' after 
the script has finished to see what happens):
------------------------------------------------------------
Running myscript.sh
******************************
@(#)MIRBSD KSH R39 2009/08/01
./myscript.sh[7]: ${.sh.version}": bad substitution
#
# lsx
-bash: lsx: command not found
#
#
------------------------------------------------------------

(note that the second line of stars is not printed !)

I the commented out the 'echo' lines showing the KSH version:

------------------------------------------------------------
#! /bin/ksh

echo "Running myscript.sh"

#echo "******************************"
#echo "${KSH_VERSION}"
#echo "${.sh.version}"
#echo "******************************"

. ./include.src

./exitcode1.sh

exit 0
------------------------------------------------------------

Running this version of the script corrupts my terminal session again (again I 
typed 'lsx' but you don't see what I enter, only the error message is shown):

------------------------------------------------------------
# ./myscript.sh
Running myscript.sh
# # -bash: lsx: command not found
                                 # #
------------------------------------------------------------

I installed the RPM from the Oracle Linux 6.1 ISO image named 
mksh-39-5.el6.x86_64.rpm. I also tried to install a newer version of MKSH today 
(mksh-40i-0.fc18.20120630.x86_64.rpm) but this requires new versions of (at 
least) glic so I cancelled the installation as I don't want to screw up 
anything. ;-)
