Dears, I need to report a bug in the manpage for 'sort'. I did consult the texinfo documentation, but it was identical to the manpage. The bug: it is not explained sufficiently how to specify fields and where the sorting options for the fields should be. An example: Using ':' as a field separator I want to sort lines in such a way that the following order results: 30:2 20:10 3:10 The options are: (1) the second field takes precedence over the first and (2) the second field is sorted numerically, the first alphanumerically. Does one specify sort -t : +1 -n +0 or sort -t : -n +1 +0 or sort -t : +1 -n -2 +0 -1 ? In fact I have tried more variants than you can immagine and none of them has the desired effect. I therefore conclude that the manpage needs an example and that I cannot supply one, because, I'm sorry, I don't get it. Please can someone help me and then update the manpage? Or let me update the manpage. Glad to. But I need the syntax explained first. Mark Roberts P.S. I haven't looked at the source yet. It's an idea though. And I havn't tried finding documentation for other 'sort'-programs which would be compatible (DEC UNIX sort, for instance). But using 'TeX', 'sort', 'gawk' and 'make' my document has an always up to date index, which is lovely. 'GNU-make' is the best program ever.
