Sorry, my earlier description was a bit unclear—my apologies. I accidentally left out the ‘$’ before INT_MAX when copying it over, but I did include the ‘$’ in my actual testing.
As for `IGNOREEOF=127`, I expected it to let me press C-d over a hundred times without exiting bash, and in my testing, this actually worked. With `IGNOREEOF=$INT_MAX`, I expected it would let me press (INT_MAX-1) times, but when I tested it, pressing C-d just once caused bash to exit immediately. It’s clear that INT_MAX really is the largest value bash allows for arithmetic operations (you can check how it’s calculated, or verify if it overflows by running `echo $[INT_MAX+1] $[INT_MAX] $[INT_MAX-1]`), but IGNOREEOF doesn’t seem to follow this limit. I think this might be a bug. If it’s not a bug, then IGNOREEOF must have its own maximum value. I’m curious: what’s the largest integer value that’s safe, valid, and effective to use in various places in bash?
