[SOLVED] BSD grep does not stop after executing

Issue

I am using BSD grep! (Different from UNIX grep) grep -e '22T1[2-4]' nagoya_all.csv -> nagoya12_14.csv

When I execute this command, nagoya12_14.csv is successfully created. However, on terminal is doesn't prompt me for a new command.

Why does this happen? How can i check if this command is still running?

Solution

Take out the - in front the redirect sign > and you should be good. When you have - at the end of a grep command, it will try to read from stdin, which waits for user input.
