It'd be easier if you threw in a *little* bit of perl:
perl -lne 'print $1 if /WARNING: (NS_ENSURE.*)/' | sort | uniq -c |
sort -nr
If you're going to use perl, you might as well use perl:
perl -e 'my %hits;
while () { $hits{$1}++ if /WARNING: (NS_ENSURE.*)/ }
printf(%d\t%s\n, $hits{$_}, $_)
for sort { $hits{$b} = $hits{$a} } keys %hits;'
Untested but, I believe, equivalent. Could perhaps be further optimized by
use of each() instead of keys() but I have forgotten too much to do it myself.

Thank you for the suggestions.
My original intent was to avoid script programming as much as possible
and yet gain reasonably good summary.
I guess the time is over for a simple shell scripting to
produce a meaningful summary from ever evolving log record.
(Yes, my script goes over the log many times and in that sense it is not
very efficient, but
it can handle 100+MiB |mach mochitest-plain| of debug build of FF in several
seconds on my local PC and not too bad for my purpose of obtaining a
meaningful summary without investing too much in programming.)
When I have a time to re-engineer my script, I will post a prototype for
review by people who may be interested in such a script.
TIA

Removing [PID] prefix from |make mozmill| warning/error/assertion lines?
Hi, I have been analyzing warning/error/assertion lines produced by full debug version of TB (comm-central). To facilitate the analysis I created a few scripts to process the error statistically. Staring 1Q of 2014, I think such lines are prefixed with [pid] . Now that probably is very good, but unfortunately, this makes it very difficult to use a simple-minded script to gather statistical information from the log. Does anyone know how to disable this prefixing short of modifying the source code? I have found that |mach| has a command for disabling timestamp (not tested yet) --log-no-timestamp. If |make mozmill| has a similar run-time option to suppress [pid' prefix, that is great. TIA PS: the lines look as follows. Note [pid] Random sampling.
