Bad substitution error :chomp:

Hello all,

I'm using Korn shell and can execute this line with no problem at the command line.


newtest=${gorseve_file//.csv/_log.txt }


gorseve_file = gorseve_8762.csv ( what the var. was)

echo $newtest

gorseve_8762_log.txt

In my script however, I receive a bad substitution error?

This is driving me crazy, been searching around for solution,

Is there another way to set a variable = to a substring

or

I think its some error with the brackets and korn shell??

thx in advance

Two things:
If you show the code that fails it is much easier to spot problems.
What you show has errors

There is a space before the = and after it, for example. But I can't tell if that is in the script.
