Fixed length fields
HPUX and posix shell

Hi all.

I have a record with fixed length fields....I would like to reorder the fields and preserver the fixed lengths....

cat test
Code:
4 960025460           Dept of Music                                           
8 960025248           Dept of Music 12-08

cat newtest
Code:
960025460            4 Dept of Music                                           
960025248            8 Dept of Music 12-08

I can get it done with this awk line, but I need to preserve the field lengths....this command will not.
Code:
awk 'begin{fieldwidths = "1 51 49"}; {print $2 $1 $3}' test > newtest

Anyone have a sed line or a better awk line?

TIA!!!!

A bit verbose, but....
Code:
gawk 'BEGIN{FIELDWIDTHS="1 51 49";orderN=split("2 1 3", orderA)}; {for(i=1;i in orderA;i++)printf("%*s%c",FIELDWIDTH[i],$orderA[i],(i==orderN)?ORS:"") }' myFile
