Column to row with delimiter
Hi, i have data in a file f1.txt
a
b
c
d

and i want to print the above column values in single line with a delimiter, say ','
The output should look like:
a,b,c,d

I could find rows to columns help online but not vice versa

Thanks,

Thanks balajesuri, i tried that except that it puts a delimiter after the last value too,
Is there a simple way to eliminate that?
Thanks,
