sed problem
I am a newbie in unix scripting so sorry if this is a dumb question. I am trying to reverse the order of first and last names if a file using sed. Here is a sample line:
Tommy Savage:408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200 Please help have no idea how to start this.

Code:
cat /var/tmp/asb.txt
Tommy Savage:408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200
sed -e 's/ /+/' /var/tmp/asb.txt
Tommy+Savage:408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200
sed -e 's/ /+/' -e 's/:/+/' /var/tmp/asb.txt
Tommy+Savage+408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200
sed -e 's/ /+/' -e 's/:/+/' /var/tmp/asb.txt |awk -F"+" '{print $2" "$1":"$3}'
Savage Tommy:408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200

To use sed we have to pattern exactness there. We have to change the pattern with replacement there.
In your example, Tommy Savage:408-724-0140:1222 Oxbow Court, Sunnyvale, CA 94087:5/19/66:34200 we knew Tommy Savage, Oxbow Court are to be changed there. But relative pattern to idenitfy them are not there. For example, if we have + symbol there then we can do sed there with identification of + there. But the symbol + must not be with other strings there. So simply to do this, sed "s/Tommy Savage/Savage Tommy/g;s/Oxbow Court/Court Oxbow/g" <inputfile> HTH.

if you try to change: aaa bbb:ccccc and more to bbb aaa:ccccc and more then note you have 2 points the space between 'b a' and the : between 'a:c' IF THEY ARE CONSTANT, the way in sed is: s/^\(.*\)\( [ ]*\)\(.*\):\(.*\)/\3\2\1:\4/ NOTE the spaces. Muthukumar_K: try to be a little more abstract
