Top Forums Shell Programming and Scripting sort file specifying record length Post 302563277 by alister on Monday 10th of October 2011 04:32:25 PM

There's nothing you can tell sort that would make the situation workable. The problem is that sort is a line-oriented tool. If there is a newline-valued byte in the binary data, sort will treat the binary data before and after that byte as individual lines.

You are going to need some way to pre-process the input before feeding it to sort, so that it can do its job properly.

If you'd like further help, we'll need to know as much as possible about the characteristics of the input data (including the always annoying-when-not-mentioned special cases).

Regards and welcome to the forum,

NAME
sort - sort a file of ASCII lines SYNOPSIS
sort [-bcdfimnru] [-tc] [-o name] [+pos1] [-pos2] file ... OPTIONS
-b Skip leading blanks when making comparisons -c Check to see if a file is sorted -d Dictionary order: ignore punctuation -f Fold upper case onto lower case -i Ignore nonASCII characters -m Merge presorted files -n Numeric sort order -o Next argument is output file -r Reverse the sort order -t Following character is field separator -u Unique mode (delete duplicate lines) EXAMPLES
sort -nr file # Sort keys numerically, reversed sort +2 -4 file # Sort using fields 2 and 3 as key sort +2 -t: -o out # Field separator is : sort +.3 -.6 # Characters 3 through 5 form the key DESCRIPTION
Sort sorts one or more files. If no files are specified, stdin is sorted. Output is written on standard output, unless -o is specified. The options +pos1 -pos2 use only fields pos1 up to but not including pos2 as the sort key, where a field is a string of characters delim- ited by spaces and tabs, unless a different field delimiter is specified with -t. Both pos1 and pos2 have the form m.n where m tells the number of fields and n tells the number of characters. Either m or n may be omitted. SEE ALSO
comm(1), grep(1), uniq(1). SORT(1)
