Shell Programming and Scripting

Is it possible to do this with sed?

Go from this:
958211 XXYYXXYYXX file1 file2 file3
958897 XXYYXXYYXX file1 file2

To this:
file1 file2 file3 XXYYXXYYXX 958211
file1 file2 XXYYXXYYXX 958897

The only thing consistant is XXYYXXYYXX. The numbers and files vary in length. I have seen I can reverse letters but this is a different story. If not sed any other thoughts? If I knew enough I could write a C program, but I do not.

One more in awk,

Code:

awk '{for(i=NF;--i>0;) if($i=="XXYYXXYYXX"){printf $i FS} else{ printf $i FS} print ""}' file

with awk,

Code:

awk -v FS="XXYYXXYYXX" '{print $2,FS,$1}' file

Another way without a pattern, to move the 1st column to the end and the 2nd column before the 1st column:

Code:

sed 's/\([^ ]*\) \([^ ]*\) \(.*\)/\3 \2 \1/' file

Wow, you all are amazing. Thanks!
