Data regarding sort command.

hi,

In UNIX I want a sort records in a file based on the certain position in the record as the key in the file.

Now if certain 2 records have the same record then the out file should have the records as the First in First out i.e. in the same order in which they occur in the input file.

Say for e.g.

There are records in the input file

12345555555555677689870987
12345
12343

And I sort it based on the the keys 1-4 so then as per the sort I need

Output file


1234555555555555555
12345
12343

but the output I get is something like this

12343
12345
12445555555555555

i.e. it gets soreted on the next one records also if the key is the same which I don't want it to happen.

Could someone please let me know if this is possible using the sort command in UNIX or any other way to do it.

Thanks
Aman.

NAME
sortbib - sort a bibliographic database SYNOPSIS
sortbib [-s KEYS] 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. The most common key-letters and their meanings are given below. %A Author's name %B Book containing article referenced %C City (place of publication) %D Date of publication %E Editor of book containing article referenced %F Footnote number or label (supplied by refer) %G Government order number %H Header commentary, printed before reference %I Issuer (publisher) %J Journal containing article %K Keywords to use in locating reference %L Label field used by -k option of refer %M Bell Labs Memorandum (undefined) %N Number within volume %O Other commentary, printed at end of reference %P Page number(s) %Q Corporate or Foreign Author (unreversed) %R Report, paper, or thesis (unpublished) %S Series title %T Title of article or book %V Volume number %X Abstract -- used by roffbib, not by refer %Y,Z Ignored by refer By default, sortbib alphabetizes by the first %A and the %D fields, which contain the senior author and date. 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 leading articles (like `A' or `The') when sorting by titles in the %T or %J fields; it will ignore articles of any modern European language. If a sort-significant field is absent from a record, sortbib places that record before other records containing that field. No more than 16 databases may be sorted together at one time. Records longer than 4096 characters will be truncated. OPTIONS
-sKEYS 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. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWdoc | +-----------------------------+-----------------------------+ SEE ALSO
addbib(1), indxbib(1), lookbib(1), refer(1), roffbib(1), attributes(5) BUGS
Records with missing author fields should probably be sorted by title. SunOS 5.10 14 Sep 1992 sortbib(1)
