Re^2: can you autoflush a program in unix?

You could make the $FLUSH variable pull it's value from an environment variable like so:

$FLUSH = $ENV{FLUSH} || 1;

The 1 is a default, which you can change to 0. That lets the user call your script from the shell as:

bash# AUTOFLUSH=1 /path/to/script.pl

Aside from the discrepancy in your variable names, you seem to have missed this paragraph of the OP Now say for example that FLUSH is NOT set and I am unable to set FLUSH (for example if I don't have permission to modify to the program).	[reply]
