echo "abc def ghi" | sed 's/\([a-z]* \)\([a-z]* \)/\2\1/'
But Perderabo, in that case, script will fail, if there is any leading space in the string, but for this particular problem, it'll work. Thanks.

sed is good but here awk is better:

Code:
$ echo "abc def ghi" | awk '{X=$1; $1=$2; $2=X; print}'
def abc ghi

or even
Code:
$ echo "abc def ghi" | awk '{print $2, $1, $3}'
def abc ghi
