What is the bash `posix mode'?
Although bash is an implementation of the POSIX.2 shell
specification, there are areas where the bash default behavior
differs from that spec. The bash `posix mode' changes the bash
behavior in these areas so that it obeys the spec more closely.
Posix mode is entered by starting bash with the --posix option or
executing `set -o posix' after bash is running.
The specific aspects of bash which change when posix mode is
active are listed in the file CWRU/POSIX.NOTES in the bash
distribution. They are also listed in a section in the Bash
Reference Manual.
