When I use grep -o to search in multiple files, it outputs each result prefixed with the file name. How can I prevent this prefix? I want the results without the file names.
Get `grep` to not output file name
grep
Use option -h. -h, --no-filename          Suppress the prefixing of file names on  output.   This  is  the          default  when there is only one file (or only standard input) to          search.
