Description Hemant Shah 1999-11-17 14:23:41 EST
I recently bought RedHat 6.1 Professional version.
Yesterday I upgraded my system to redhat Linux 6.1. Many of my shell
scripts stopped working because they contained "typeset -r"
commands.

Example:
---------------------------------------------------------------
#!/bin/ksh

typeset -r ExeName=${0##*/}
typeset -r NiceOpt=""
print $ExeName
date
---------------------------------------------------------------

When I execute above script I get following message:

/tmp/tst.ksh[3] ExeName: is read only
/tmp/tst.ksh[4] NiceOpt: is read only

As you can see ExeName is not set.

Here is the output of uname -a before upgrade:
Linux lidp14 2.0.34 #21 Thu Apr 29 12:22:41 CDT 1999 i586 unknown

Here is th output of uname -a after upgrade:
Linux lidp14 2.2.12-20 #1 Mon Sep 27 10:25:54 EDT 1999 i586 unknown

Please respond ASAP, all my administrative scripts are not working.

Thanks.

I don't think you can assign at the same time you set the "-r" attribute - do it
like this instead:

ExeName=${0##*/}
NiceOpt=""
typeset -r ExeName
typeset -r NiceOpt
print $ExeName
