egrep -f

Hi,
i am using egrep -f. The file with the expressions is very big and if i make the file a lot smaller, it works fine. Only if i use the original file, witch has about 20.000 lines it doesn't seem to work. Is the file to big, or do i need more patience??

my command is:
egrep -f studenten.uid hsa.csv > studentMail.csv

I don't know what the exact limits might be, but I've heard grep can handle a file of about 400 lines, and higher in some instances, but 20000 is almost certainly too many. When you made the file smaller and it worked correctly, how many lines were in the file?
