linux - Edit field with date in .csv -


i have .csv file lines this:

xxxx,xxxxxx,sep  1, 2015 21:32:15.xxxxxxxxx west xxxx,xxxxxx,sep 28, 2015 23:46:16.xxxxxxxxx west xxxx,xxxxxx,sep 30, 2015 21:23:17.xxxxxxxxx west

and need change date , time this:

xxxx,xxxxxx,2015-09-01,21:32:15 xxxx,xxxxxx,2015-09-28,23:46:16 xxxx,xxxxxx,2015-09-30,21:23:17

i think it's possible using awk , date until nothing worked.

some perl:

perl -mtime::piece -f, -lape '   ($d2, $d1) = (pop(@f), pop(@f));   $d2 =~ s/\..*//;   push @f, time::piece->strptime($d1.$d2, "%b %e %y %t")->strftime("%y-%m-%d,%t");   $_ = join ",", @f; ' file

that removes last 2 comma-separated fields each line, deletes fractional time , timezone, reformats time , prints.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
