How to append filename to rows in gzip stdout
Assume I have 2 gz files with 2 lines each as below
a.gz
Code:
a1,a
a2,a

b.gz
Code:
b1,b
b2,b

If I issue
Code:
gzip -d -c *.gz

I will get below in the stdout
Code:
a1,a
a2,a
b1,b
b2,b

What I need it the filename appended to each row either at the front or back.
Code:
a.gz,a1,a
a.gz,a2,a
b.gz,b1,b
b.gz,b2,b

Can the above be done with a single command and output to stdout?

do
    gzip -d -c $file | awk -v f=$file '{print f ","  $0}'
done
