The documentation for my version of GNU sort (textutils 2.0) states: The `-b' option may be independently attached to either or both of the `+POS' and `-POS' parts of a field specification, and if it is inherited from the global options it will be attached to both. However, when I specify the `-b' option globally, then it is not attached to both parts of the field specification. For example, given this text file: date: 05/Jun/2001 date: 30/May/2001 The following commands act differently: $ sort -b -k2.4,2.6M test date: 05/Jun/2001 date: 30/May/2001 $ sort -k2.4b,2.6Mb test date: 30/May/2001 date: 05/Jun/2001 Let me know if you need more information. I am running this on the current "unstable" version of Debian GNU/Linux, which I believe is called "sid".
