variables work at the token level instead of line

[triorbonk]

I am working on parsing a syslog and trying to enter a variable for the date and time. The date format is "Mmm dd hh:mm:ss" the spaces in the date are split out as tokens then the tokens are replaced. This causes a problem when trying to replace the day "dd" as the pattern is to simple and replaces data I don't want to.
Can the variable functionality be applied before the line is tokenized?

command using
cat system.log | logmine -p'*' -v time:"/\d{2}:\d{2}:\d{2}/" month:"/Mar/" day:"/[1-3]?[0-9]/" -c

Hi there! This is not possible with the algorithm. However, you can preprocess your log before piping it to logmine. For example:

cat system.log | sed -En "s/Mar [[:digit:]]{2} [[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2}/<date-time>/p" | logmine

I got this output:

18 <date-time> xxx com.apple.xpc.launchd[1] (com.apple.mdworker.shared.0D000000-0700-0000-0000-000000000000[15944]): Service exited due to SIGKILL | sent by mds[92]
