grep -f not working
Hello, I'm going crazy about this. I'm using grep to filter some values as in pas -ef | grep asterisk. When I use the same with -f somefile something weird happens, if somefile is created with vi it'll work, if somefile is created with vi but values are pasted from an Excell file it will not work. If somefile is created using a script that reads from a file and extracts 1 fiels using awk it will not work.
Any ideas why?

The excel file has ^M characters - DOS carriage control
Code:
dos2unix inputfile > newinputfile

yes, I changed the format to linux and still didn't work. I had to edit the file with vi, add and erase a blank line and now it works.
