I should clarify a couple of points.
the missing backslashes cause the script to prompt me to enter a
password. These scripts are usually run with the password embedded as "
:some_password \" and the results are the same. I don't buy the changed
script argument because I have many frozen copies to compare with.
However, noglob suggestion is good. It's possible that this distro
upgrade changed the shell configuration from previous. I will follow
this lead. Thanks.
