This prints out time (in s since 1970) and line number+content to aid in profiling a bash script. Taken from: http://stackoverflow.com/questions/4336035/performance-profiling-tools-for-shell-scripts Note, that sometimes the first digit gets chopped off the date :/
PS4='$(date "+%s.%N ($LINENO) + ")' bash -x scriptname

Prints out event content during path run (like edmDumpEventContent)
process.eca= cms.EDAnalyzer("EventContentAnalyzer"
#getData = cms.untracked.bool(True),
#listContent = cms.untracked.bool(False)
)
then later on
process.p = cms.Path( ... + process.eca + ... )
