Hi Experts,
I am facing issues in getting the correct regexp for this use-case. Sorry
for the 2nd question of the day :-(

pci@:5e:00.2
pci@:5e:00.3
pci@:d8:00.0
pci@:d8:00.1
I need to fetch ":19:00.0" through ":d8:00.1" in a string.. I

Want to search for a substring in a huge string ( output of a exec.command)
and get the index for every occurrence of that substring. I used Index and
LastIndex, both give first and last, but am looking for
cat`. The

command prompt:
Lang : GOLANG
OS : Linux/Centos
Problem : Using exec.command to get the output of a certain file
Error: Getting no such
