Chapter 9. Package And Driver Changes

forces them to be matched literally. This is consistent with how the == pattern matching operater treats

quoted portions of its pattern argument.

Since the treatment of quoted string arguments was changed, several issues have arisen, chief among

them the problem of white space in pattern arguments and the differing treatment of quoted strings

between bash 3.1 and bash 3.2. Both problems may be solved by using a shell variable to hold the

pattern. Since word splitting is not performed when expanding shell variables in all operands of the

[[ command, this provides the ability to quote patterns as you wish when assigning the variable, then

expand the values to a single string that may contain whitespace. The first problem may be solved by

using backslashes or any other quoting mechanism to escape the white space in the patterns.

Bash 4.0 introduces the concept of a compatibility level, controlled by several options to the shopt

builtin. If the compat31 option is enabled, bash will revert to the 3.1 behavior with respect to quoting

the right-hand side of the =~ operator.
