how to sort lines in the string
Hi guys,
I am trying to sort numbers in the string in descending order but for some reason sort fails.

Code:
n129$ echo "81 240" | sort -r
81 240
n129$

I am not sure what am I doing wrong. Is there a 100% reliable way to make sure that sort will always work. I mean on SUNS and IBM machines.
Thanks a lot.

Sort works when numbers are seperated by newline so u can try something like below..

Code:
 echo "81 240" |tr ' ' '\n'|sort|tr '\n' ' '

try this as you want in descending order..Smilie

Code:
$ echo "81 240 21 365 20 1 25 95 32" | tr ' ' '\n'| sort -nrk1 | tr '\n' ' '
365 240 95 81 32 25 21 20 1

Since you aren't using sort's -n option, you're also performing a sort using string comparisons rather than numeric comparisons.
