How to remove trailing new line

say, my file name emp.txt contains the following :



sriram

rajesh

khanna

raghu

sekhar

teja



I want to remove the new line after every name and write them in a csv format :



awk '{print $1}' /tmp/my | tr '\n' ',' will give us comma seperated output :



sriram,rajesh,khanna,raghu,sekhar,teja
