bash - How to run sctipt b based on script a result -


i've got 2 working sctipts: a.sh, b.sh.

i create 1 script following: 1. run a.sh 2. running b.sh dependant on output of a.sh wait string a.sh standatd output saying 'a.sh launched' run b.sh if trickyto implement perhaps wait 2 minutes before running second script.

what best way acheiving this?

continuously reads output of a.sh , when encounters "a.sh launched" launches b.sh.

./a.sh | while read line;     echo $line      # if want see output of a.sh     [ "$line" == "a.sh launched" ] && ./b.sh & done

if want match

a.sh lounched @ `date`

use advanced bash comparsion

[[ "$line" =~ "a.sh lounched".* ]]

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...
