hi ddreggors/jim

i tried this - and it fails with the below error

sed -i '1 i \HeaderText' ExtractDataFile.txt
sed: illegal option -- i

The system is a SunOS ussun1l 5.8 Generic_117350-60 sun4u sparc SUNW,Sun-Fire-15000

the perl option is out for me as the client may not want to install any piece of software without business cause, however as long as the tmp file is created in the /tmp space and not my file-dir i think i'm ok - any more ideas anyone?
