Merging multiple log files by date including multilines

Question

I have several logs containing lines all starting with a timestamp, so that the following works as expected to merge them:

cat myLog1.txt myLog2.txt | sort -n &g         


        

Answer 1

The open source tool (Java GitHub) lets you combine log files with different formats including multilines into a merged file.

The tool allows to shift the time of records in a log file. It can be useful when files come from different time zones.

It also allows to generate additional information to a merged file, for example applications names or timestamps in a uniform format, see the example.

The tool can be used as a command line tool or Java library. Note: I'm the author.
