NAME
rank - Rank lines of text
VERSION
This document describes version 0.004 of rank (from Perl distribution App-rank), released on 2018-04-25.
SYNOPSIS
rank [OPTION]... [FILE]...
DESCRIPTION
rank
ranks lines of text, by default using the first field as the sort key (can be changed with --sort-field
option). When there are multiple lines that have the same sort key, rank
will assign the same rank to the lines. Finally, the lines will be displayed with the ranks, starting from the highest ranked (1).
Sample input:
21 ujang
30 budi
50 atang
75 robi
89 parjiyem
77 nono
75 tedi
Sample output using rank -n
:
1 89 parjiyem
2 77 nono
3 75 robi
3 75 tedi
5 30 budi
6 21 ujang
Sample output using rank -np
:
1 100.000 89 parjiyem
2 85.714 77 nono
3 71.429 75 robi
3 71.429 75 tedi
5 42.857 30 budi
6 14.286 21 ujang
EXIT CODES
0 on success.

OPTIONS
--action=s (default: rank)
Valid values:
rank
,calc-percentile
--calc-percentile=f, ...
Imply
--action=calc-percentile
. Calculate specific percentile(s). Will use linear interpolation to get the percentile values.--reverse, -r
--ignore-leading-blanks, -b
--ignore-case, -i
--field-separator, -f (default: Tab)
--sort=s
--numeric-sort, -n
--sort-field=i (default: 0)
rank=s (default: default)
Change ranking system. The default is to have all lines that have the same sort keys to be ranked the same, but the next ranking will skip numbers:
1 89 parjiyem 2 77 nono 3 75 robi 3 75 tedi 5 30 budi 6 21 ujang
The
no-skip
ranking system will not do these skips:1 89 parjiyem 2 77 nono 3 75 robi 3 75 tedi 4 30 budi 5 21 ujang
The
no-same
ranking system will assign different ranks to lines that have the same sort key:1 89 parjiyem 2 77 nono 3 75 robi 4 75 tedi 5 30 budi 6 21 ujang
--no-show-rank
--show-percentile, -p
