grep gives only 'file xx matches'
I try to find a certain error in a syslog with
grep panic /var/log/syslog
which works on several of my servers and shows the lines with panic, but not on one specific server (which is set up the same than the others). On this server I get only
Binary file /var/log/syslog matches
which is close to what I would get with the -l option. What can be wrong that I do not get the regular output, i.e. the lines which contain the word panic

thank you for the hint - forcing grep to take syslog as text file with the--textflag resolved the issue. I remain puzzled why syslog is considered a binary file on one of the servers but not on the others.

The command which worked - as hinted by melpomene - was
grep panic /var/log/syslog --text
to force grep to consider syslog a textfile, not a binary file.
