Thanks for the reply. If it works for you, doesn't work on my home or
work computer & upgrading doesn't fix it ... it's probably something I
did. Which it was - I had this bit in my c:\cygwin\cygwin.bat file:
@rem set LANG envar for proper display
@rem ref: http://cygwin.com/cygwin-ug-net/setup-locale.html
set LANG=en_US.UTF-8
Comment out the 'set LANG=" and gsub works fine:
$ echo $LANG
C.UTF-8
$ sh /tmp/test.awk
s= ::S0:: should = ::S0::
$ export LANG=en_US.UTF-8
$ sh /tmp/test.awk
s= ::0:: should = ::S0::
So awk gsub works for me again - thank you!
Just out of curiosity, why would setting LANG to en_US break
case-sensitivity in gsub?
Regards,
Lee
