change order of fields in header record
Hello,
after 9 months of archiving 1000 files, now, i need to change the order of fields in the header record. some very large, space padded files. HEADERCAS05212008D0210DOMEST01(spacepadded to record length 210) must now be 05212008HEADERCASD0210DOMEST01(spacepadded to record length 210) Does anyone know a way to manipulate the first record only and resave the file? I appreciate your time and expertise Thanks

An example how you can achieve that:
Code:
awk 'NR==1{print substr($0,10,8) substr($0,1,9) substr($0,18);next}1' file > file_temp
mv file_temp file
