linux - Grepping and grouping for errors in log files -


i'm on linux (and on aix) , have bunch of log files in folder. have grep command filter out of errors in format follows.

createorder_hostname_tee.log:2015-09-29 15:42:06,715:error  :thread-26_createorder: [1443555726715] error1  [system]: class1 createorder_hostname_tee.log:2015-09-29 15:42:06,715:error  :thread-15_createorder: [1443555726715] error1  [system]: class1 createorder_hostname_tee.log:2015-09-29 15:42:06,715:error  :thread-28_createorder: [1443555726715] error2  [system]: class2 scheduleorder_hostname_tee.log:2015-09-30 03:55:05,011:error  :thread-5_scheduleorder: [1443599705009] error3  [system]: class3

is possible using combination of grep/awk/sed above data in format this?

api: error: count createorder: error1: 50 createorder: error2: 50 scheduleorder: error3: 50

if not, possible format this? use wc or similar count distinct errors.

api: date: error createorder: 2015-09-29 15:42:06,715: error1 createorder: 2015-09-29 15:42:06,715: error2 scheduleorder: 2015-09-29 15:42:06,715: error3

edit 1:

the error string (including spaces). basically, in between brackets below should displayed.

[1443555726715] error1: error description.  [system]: class1 

input=$(your grep command) formatted=$(   echo "$input" |     sed 's/^\([^_]*\).*[0-9]*\] \([^[]*[^\[ ]\).*/\1: \2/' ) kinds=$(echo "$formatted" | sort -u) while ifs= read kind   count=$(echo "$formatted" | grep "$kind" | wc -l)   echo "$kind: $count" done <<< "$kinds"

for input given in question, gives output:

createorder: error1: 2 createorder: error2: 1 scheduleorder: error3: 1

everything done in memory, might not feasible large data structures (dozens or hundreds of megabytes). in these cases can use temporary files instead of shell variables (e. g. echo "$input" | sed … > formatted.tmp , sort -u formatted.tmp > kinds.tmp etc.).

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

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...
