Further to post #5 , you'd need to read the file line-by-line, then sort the contents of the line. Also lose the "-s" switch to "tr".

Code:
cat filename.txt | while read line
do
        sorted=`echo "${line}" | tr " " "\n"| sort -n | tr "\n" " "`
        echo "${sorted}" | sed 's/ $//g'
done

./scriptname
1 2 3 4 5 6 7 8
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26
31 32 33 34 35 36 37 38

Script has a flaw because it introduces a trailing space character on each record, hence the sed to remove that character.


If you have a modern Shell, the newer syntax is preferred:
Code:
while read line
do
        sorted=$(echo "${line}" | tr " " "\n"| sort -n | tr "\n" " ")
        printf "${sorted}\n" | sed 's/ $//g'
done < filename.txt

fc-match

FC-MATCH(1)															       FC-MATCH(1)

NAME

       fc-match - match available fonts

SYNOPSIS

       fc-match [ -asvVh ] [ --all ] [ --sort ] [ --verbose ] [ -f format | --format format ] [ --version ] [ --help ]
	   [ pattern  [ element ... ]  ]

DESCRIPTION

       fc-match  matches pattern (empty pattern by default) using the normal fontconfig matching rules to find the best font available.  If --sort
       is given, the sorted list of best matching fonts is displayed.  The --all option works like --sort except that no pruning is  done  on  the
       list of fonts.

       If  any elements are specified, only those are printed.	Otherwise short file name, family, and style are printed, unless verbose output is
       requested.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.

       -a --all
	      Displays sorted list of best matching fonts, but do not do any pruning on the list.

       -s --sort
	      Displays sorted list of best matching fonts.

       -v --verbose
	      Print verbose output of the whole font pattern for each match, or elements if any is provided.

       -f --format format
	      Format output according to the format specifier format.

       -V --version
	      Show version of the program and exit.

       -h --help
	      Show summary of options.

       pattern
	      Displays fonts matching pattern (uses empty pattern by default).

       element
	      If set, the element property is displayed for matching fonts.
