Hi Andreas,
Sure, the variables explicitly assigned to get exported, that is the
expected behavior.
But there is nothing which explains why the variable COLUMNS becomes an
environment variable.
Run “ps ax” twice and the results of the second execution is different from
the first if and only if “set -a” was called fiirst. This is NOT an expected
behavior.
Do the following and you won’t get a problem:
set -a
var1=xx
var2=xx
set +a
All is fine, but do the following and COLUMNS gets exported:
set -a
echo $PATH | grep xxx/scripts || PATH=${PATH}:/newdir
ps ax is now truncated, definitely NOT expected
Regards,
Alain

Why do you think this is a bug in bash? You are telling the shell to export any
