Approach on Header record

view full story

http://www.unix.com – All, I currently have a requirement to fetch a Date value from a table. And then insert a Header record into a file along with that date value. ex: echo "HDR"" "`date +%Y%j` `date +%Y%m%d` In the above example I used julian date and standard date using Current Date. But the requirement here is to use a Date value fetched from a database table. Kindly help me please. (HowTos)
