trace-cmd-split - split a trace.dat file into smaller files
trace-cmd split [OPTIONS] [start-time [end-time]]
The trace-cmd(1) split is used to break up a trace.dat into small files. The start-time specifies where the new file will start at. Using trace-cmd-report(1) and copying the time stamp given at a particular event, can be used as input for either start-time or end-time. The split will stop creating files when it reaches an event after end-time. If only the end-time is needed, use 0.0 as the start-time.
If start-time is left out, then the split will start at the beginning of the file. If end-time is left out, then split will continue to the end unless it meets one of the requirements specified by the options.
This option will change the name of the base file used.
-o file will create file.1, file.2, etc.
Note: only one of *-p*, *-e*, *-u*, *-m*, *-s* may be specified at a time.
If *-p* is specified, then *-c* is automatically set.
trace-cmd split -r -e 10000
This will break up trace.dat into several smaller files, each with at most 10,000 events in it.
trace-cmd split -c -p 10
This will create a file that has 10 pages per each CPU from the input.
trace-cmd split -C 1
This will split out all the events for cpu 1 in the file.
