Hi.

Utility msort allows alternate sequences:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate alternate collating sequence, msort.
# For msort, see your local repository or,
# http://www.billposer.org/Software/msort.html
# Verified: Wed Oct 21 11:02:51 CDT 2015

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
LC_ALL=C ; LANG=C ; export LC_ALL LANG
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C msort column

FILE=${1-data1}

pl " Input data file $FILE:"
cat $FILE

pl " Sort order file (columnized):"
column custom-1.txt

pl " Results:"
msort -q -j -l -n 1,1 -s "custom-1.txt" $FILE

exit 0

producing:
Code:
$ ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64

bash GNU bash 3.2.39
msort 8.44
column - ( /usr/bin/column, 2007-11-20 )

 Sort order file (columnized):
X	A	D	G	J	M	P	S	V

I have found msort in Debian, Ubuntu, Fedora, MiNT, OSX (port), etc. Otherwise see the link in the script comments.

Best wishes ... cheers, drl

rup

rup(1C) 						      Communication Commands							   rup(1C)

NAME

       rup - show host status of remote machines (RPC version)

SYNOPSIS

       rup [-hlt]

       rup [host]...

DESCRIPTION

       rup gives a status similar to uptime for remote machines. It broadcasts on the local network, and displays the responses it receives.

       Normally,  the  listing	is in the order that responses are received, but this order can be changed by specifying one of the options listed
       below.

       When host arguments are given, rather than broadcasting rup only queries the list of specified hosts.

       A remote host will only respond if it is running the rstatd daemon, which is normally started up from inetd(1M).

OPTIONS

       -h    Sort the display alphabetically by host name.

       -l    Sort the display by load average.

       -t    Sort the display by up time.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
