Filter the output of a file continously using tail and grep

tail -f $FILENAME | grep --line-buffered $PATTERN
The OPs solution will work, however on some systems (bsd), grep will not filter the data, unless the --line-buffered option is enabled.

What Others Think

Using this simple command, one can continuously filter the output of the file utilizing only grep and tail. I am so thankful to you for creating this remarkable command for us. Other than your source, I have taken some additional help from the article to improve the learning experience of my students. Hopefully, my students would be able to easily remember it.
