My understanding was that by using -nrk2,1 the fields would be sorted (reverse) numerically by field 2, then by field 1 (presumably alphabetically - which was wrong).
If you try
Then that's OK (numerically), but the rest (-nrk2,1) doesn't sort the first field after that as I thought.
Sort is a powerful command if you can master it - something I have neither the time nor inclination to do!
Given that the records are sorted reverse numerically in field 2 with "sort -nrk2"...
the awk says:
if I don't have a color (where $1 = purple, or whatever) in my array (C[purple]), then define something (anything) for purple (C[$1]=1) so that I do, and then print the line. If I do have something already defined, then do nothing (thus printing only the first line with each (sorted) color).

So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

sortbib
SORTBIB(1) General Commands Manual SORTBIB(1)NAME
sortbib - sort bibliographic database
SYNOPSIS
sortbib [ -sKEYS ] database ...
DESCRIPTION
Sortbib sorts files of records containing refer key-letters by user-specified keys. Records may be separated by blank lines, or by .[ and
.] delimiters, but the two styles may not be mixed together. This program reads through each database and pulls out key fields, which are
sorted separately. The sorted key fields contain the file pointer, byte offset, and length of corresponding records. These records are
delivered using disk seeks and reads, so sortbib may not be used in a pipeline to read standard input.
By default, sortbib alphabetizes by the first %A and the %D fields, which contain the senior author and date. The -s option is used to
specify new KEYS. For instance, -sATD will sort by author, title, and date, while -sA+D will sort by all authors, and date. Sort keys
past the fourth are not meaningful. No more than 16 databases may be sorted together at one time. Records longer than 4096 characters
will be truncated.
Sortbib sorts on the last word on the %A line, which is assumed to be the author's last name. A word in the final position, such as
``jr.'' or ``ed.'', will be ignored if the name beforehand ends with a comma. Authors with two-word last names or unusual constructions
can be sorted correctly by using the nroff convention `` '' in place of a blank. A %Q field is considered to be the same as %A, except
sorting begins with the first, not the last, word. Sortbib sorts on the last word of the %D line, usually the year. It also ignores lead-
ing articles (like ``A'' or ``The'') when sorting by titles in the %T or %J fields; it will ignore articles of any modern European lan-
guage. If a sort-significant field is absent from a record, sortbib places that record before other records containing that field.

BUGS
Records with missing author fields should probably be sorted by title.
