Weird issues with grep over logs
Weird issue I’ve never seen before
cat /var/log/logfile.log | grep "magic" Binary file (standard input) matches
So let’s check the file datatype:
file /var/log/logifle.log data
What is happening?
So, somehow, a text based log file is identified as binary? It’s apparently caused by a NULL character spilled to the log
Solution is to filter out the NULL character first.
cat /var/log/logfile.log |tr -d '\000'| grep "magic" magic
