Hi, Mandar,

I think your ksh is not Version 93. Here's from UWin (Korn shell for Windows, www.research.att.com/sw/tools/uwin/):

$ var=tester
$ echo $var

tester
$ echo ${var//e/o}

tostor

Unfortunately, it's not easy to get ksh93 on a UNIX box due to (I believe) licensing issues.

Q24. How do I do global substitutions on the contents of shell variables? A24. Use // instead of / for global substitution, ${var//aa/bb} will expand to the value of with each "aa" replace by "bb".

so i tried
$ var=tester
$ echo $var

tester
$ echo ${var//e/o}

bad substitution
$

anyone out there :)
