grep gives only 'file xx matches'












0















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






grep

    Hint: Read the first word of grep's output.

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