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

NAME
evmsort - sort events SYNOPSIS
show_template]] sport_spec] [filename | DESCRIPTION
The command reads and sorts a stream of EVM events. By default, events are read from and are sorted into ascending timestamp order. Sorted events are written to the command's stream in the form of raw EVM events. The sort order can be specified by supplying a sort_spec, either through the option or by setting the environment variable to the required specification. The specification is a character string of the form: key_item[ The key_item is the name of any EVM standard data item and the character is optional. If the special key_item is specified, the event's data item is expanded as described in the evmshow(1) manpage, and the resulting string is used as the sort key. The optional trailing or character indicates ascending or descending sort. By default, items are sorted in ascending order. Multiple items in the string are separated by colon characters The left-most key_item in the specification is the most significant key. If a key_item that is included in the sort specification is not present in an event read from the input stream, the item is considered to have a low value for that event. For example, if input events are being sorted in ascending order according to their data items, and one event does not contain a name, that event appears first in the output stream. If the option is specified, automatically starts and pipes the sorted event stream into it, producing a sorted and formatted display of events. If a argument is also specified with the specified template string is passed to through its own option. See the evmshow(1) manpage for more information. Options Automatically starts to produce a formatted display of the sorted events. The specification to be used in sorting events. See the section for the syntax of the sort_spec, and for details of the default sort order. Template string to be passed to if the option is also specified. If the option is not specified, this argument is ignored. See the evmshow(1) manpage for a description of the template string. Operands filename Reads event sources from filename. If filename is omitted, or is specified as event sources are read from EXTERNAL INFLUENCES
Environment Variables The following environment variables affect the execution of This variable contains a string formatted as described for a sort_spec. If the option is omitted, the string is used as the sort_spec. RETURN VALUES
The following exit values are returned: Successful completion. An error occurred. EXAMPLES
o The following example retrieves all events with a priority of 300 or greater, sorts them into descending order of priority (most urgent event first) and then ascending order of time (oldest event first), and automatically runs to display them. o The following example yields a list of all events, sorted with the latest event first within o The following example yields a list of all events, sorted first in order of their formatted messages and then sorted in ascending order of time. Events are passed to for display and subsequently to the command for viewing. WARNINGS
The command rejects attempts to output raw events to a terminal device. SEE ALSO
