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


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

v_date="$( date +%Y%m%d )"

while read line
        echo "${v_date}|${v_memb}${line}"
done < "$v_file"

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

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

I just want to get this in a single line.

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

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 Smilie
