tail | grep
The program that is running on my machine generates log files. I want to be able to know the number of lines that contain "FT" in the most recent log file. I wrote the following, but it always returns zero. And I know the count is not zero. Any ideas?
ls -rt *.log | tail -n 1 | grep -c FT
