the input of the file looks like below and the file type is .txt
first Line in the abcd.txt is as follows

FN|LN|DOB|ADDRESS|ZIP

The out put should be the same abcd.txt file and the first line should looks like below

20130807|abcd20130807.txtFN|LN|DOB|ADDRESS|ZIP

Thanks

Thanks Yoda for your reply,

But some how the script is throwing some exceptions.

I am trying to run this as a AWK script and it throws exceptions.

The file name I am getting is abcd.txt and I need to append the

20130807|abcd20130807.txtFN|LN|DOB|ADDRESS|ZIP

to the first line.. so I am running a awk script to do this...

I created a awk script like below

#!/usr/bin/awk -f
BEGIN {system("date '+%d%m%Y''|abcd.")system("date '+%d%m%Y'.txt");FS="|"; OFS="|"; } { print $1,$2,$3,$6,$5};

But the out put I am getting like below

07082013|abcd
07082013.txt
FN|LN|DOB|ADDRESS|ZIP

I just want to get this in a single line.

Thanks

Try this:

awk -v DT="$(date +%Y%m%d)" '{print DT,"abcd"DT".txt"$0}' OFS=\| abcd.txt

Output:

20130807|abcd20130807.txtFN|LN|DOB|ADDRESS|ZIP

I tried the code, it works, but it appends the syntax to all the lines. I just want to put this in the very first line.
May be some small changes needs to be done :slight_smile:
