Top Forums UNIX for Advanced & Expert Users Should I say "field 8" or "column 8" in this case? Post 302784433 by jim mcnamara on Friday 22nd of March 2013 07:43:52 AM

Good points, all.

I view fields as objects that are horizontally delimited and not in a fixed position, like drl.
I remember fields from FORTRAN and some versions of BASIC. Now the main driver seems to be portability of data files from UNIX into Excel.

UNIX uses field separators:
sort has a notion of fields delimited by -t [character].
from man sort for GNU sort
Code:
-t, --field-separator=SEP

awk has had FS from its inception.

NAME
cssort -- Czech sort FORMAT
cssort [ "-c"list | "-f"list ["-d"regexp]] [files ...] SYNOPSIS
cssort -c10-15,50-,25-45 < file cssort -f3,5-6 < file cssort -f3,5-6 -s: < file DESCRIPTION
Cssort is a utility that sorts input lines according to rules used in the Czech language. You can run it without any options, then it just uses whole lines for sorting. With the options, it's possible to specify parts of the lines to be used for comparison. list A comma-separated list of integer field numbers or field ranges. The are indexed from 1 and if a range is open (eg. "5-"), it means all remaining fields from the starting number. -c Stands for columns and the list that follows specifies byte ranges on the line. You will probably use this option to sort data with fixed width fields. -f Fields that will be used for sort. -d Delimiter that separates fields in the -f option. It is a Perl regular expression, the default is "[ ]+", which means any number of spaces or tabs in a row. The program assumes ISO-8859-2 encoding. Some way to specify another input encoding will come in the next versions. If you need to sort files with different encodings, you might want to check the cstocs conversion utility. SEE ALSO
